Optimization of concurrent production of xylanolytic and pectinolytic enzymes by Bacillus safensis M35 and Bacillus altitudinis J208 using agro-industrial biomass through Response Surface Methodology
Authors: Thite Vihang S. , Nerurkar Anuradha S. , Baxi Nandita N.
Published: March 2020

Application of crude xylanolytic and pectinolytic enzymes in diverse industrial processes make these enzymes commercially valuable and demand their production process to be cost-effective. Out of four different agrowaste biomass, wheat bran (WB) and citrus peel (CP), when amended as fermentation substrates, respectively induced the highest xylanolytic enzymes and pectinolytic enzymes from both, B. safensis M35 and B. altitudinis J208. Further, the simultaneous amendment of WB and CP yielded concurrent production of these cellulase free xylanolytic and pectinolytic enzymes. Hence, the quadratic model was developed using the Central Composite Design of Response Surface Method (CCD-RSM). The model gave the concentration values for WB and CP substrates to be amended in one single production medium for obtaining two optimized predicted response values of xylanase activity and pectinase activity units, which were further practically validated for the xylanase and pectinase production responses from the optimized production medium (OPM). These practically obtained response values from OPM were found to be in accordance with a range of 95% predicted intervals (PI) values. These observations verified the validity of the predicted quadratic model from RSM and suggested that both xylanase and pectinase enzymes can be induced concurrently from both of the bacterial strains.
Audience spontaneous entrainment during the collective enjoyment of live performances: physiological and behavioral measurements
Authors: Ardizzi Martina , Calbi Marta , Tavaglione Simona , Umiltà Maria Alessandra , Gallese Vittorio
Published: March 2020

Cardiac synchrony is a crucial component of shared experiences, considered as an objective measure of emotional processes accompanying empathic interactions. No study has investigated whether cardiac synchrony among people engaged in collective situations links to the individual emotional evaluation of the shared experience. We investigated theatrical live performances as collective experiences evoking strong emotional engagement in the audience. Cross Recurrence Quantification Analysis was applied to obtain the cardiac synchrony of twelve spectators’ quartets attending to two live acting performances. This physiological measure was then correlated with spectators’ emotional intensity ratings. Results showed an expected increment in synchrony among people belonging to the same quartet during both performances attendance and rest periods. Furthermore, participants’ cardiac synchrony was found to be correlated with audience’s convergence in the explicit emotional evaluation of the performances they attended to. These findings demonstrate that the mere co-presence of other people sharing a common experience is enough for cardiac synchrony to occur spontaneously and that it increases in function of a shared and coherent explicit emotional experience.

Gas accretion damped by dust back-reaction at the snow line
Authors: Gárate Matías , Birnstiel Til , Dra̧żkowska Joanna , Stammler Sebastian Markus
Published: March 2020

Context. The water snow line divides dry and icy solid material in protoplanetary disks. It has been thought to significantly affect planet formation at all stages. If dry particles break up more easily than icy ones, then the snow line causes a traffic jam because small grains drift inward at lower speeds than larger pebbles.

Aims. We aim to evaluate the effect of high dust concentrations around the snow line onto the gas dynamics.

Methods. Using numerical simulations, we modeled the global radial evolution of an axisymmetric protoplanetary disk. Our model includes particle growth, the evaporation and recondensation of water, and the back-reaction of dust onto the gas. The model takes into account the vertical distribution of dust particles.

Results. We find that the dust back-reaction can stop and even reverse the net flux of gas outside the snow line, decreasing the gas accretion rate onto the star to under 50% of its initial value. At the same time, the dust accumulates at the snow line, reaching dust-to-gas ratios of ɛ ≳ 0.8, and it delivers large amounts of water vapor towards the inner disk as the icy particles cross the snowline. However, the accumulation of dust at the snow line and the decrease in the gas accretion rate only take place if the global dust-to-gas ratio is high (ε0 ≳ 0.03), the viscous turbulence is low (αν ≲ 10−3), the disk is large enough (rc ≳ 100 au), and only during the early phases of the disk evolution (t ≲ 1 Myr). Otherwise the dust back-reaction fails to perturb the gas motion.
Null-controllability of perturbed porous medium gas flow
Authors: Geshkovski Borjan
Published: March 2020

In this work, we investigate the null-controllability of a nonlinear degenerate parabolic equation, which is the equation satisfied by a perturbation around the self-similar solution of the porous medium equation in Lagrangian-like coordinates. We prove a local null-controllability result for a regularized version of the nonlinear problem, in which singular terms have been removed from the nonlinearity. We use spectral techniques and the source-term method to deal with the linearized problem and the conclusion follows by virtue of a Banach fixed-point argument. The spectral techniques are also used to prove a null-controllability result for the linearized thin-film equation, a degenerate fourth order analog of the problem under consideration.
Evaluation of the properties of plastic-metal interfaces directly bonded via injection molding
Authors: Horiuchi Shin , Terasaki Nao , Itabashi Masami
Published: March 2020

Plastic and metal can be directly bonded via insert injection molding by creating surface porous structures with 30–50 nm sizes on metal surface. Molten polymers can be penetrated into the small pores created on metal surface in the short molding process, and strong joint can be obtained. The bonding mechanism of aluminum alloy (Al5052) and polyphenylene sulfide (PPS) with two different surface features of Al5052 was studied. Scanning transmission electron microscopy (STEM) was performed to investigate the interfacial structures in terms of elemental distributions and three-dimensional (3D) inter-connectivity of the pores on the Al5052, and the chemical reaction which takes place during the joint process was investigated by X-ray photon spectroscopy (XPS). The properties of the joint interfaces were evaluated to discuss the effect of interfacial structures on the joint properties.
A probabilistic approach to quasilinear parabolic PDEs with obstacle and Neumann problems
Authors: Xiao Lishun , Fan Shengjun , Tian Dejian
Published: March 2020

In this paper, by a probabilistic approach we prove that there exists a unique viscosity solution to obstacle problems of quasilinear parabolic PDEs combined with Neumann boundary conditions and algebra equations. The existence and uniqueness for adapted solutions of fully coupled forward-backward stochastic differential equations with reflections play a crucial role. Compared with existing works, in our result the spatial variable of solutions of PDEs lives in a region without convexity constraints, the second order coefficient of PDEs depends on the gradient of the solution, and the required conditions for the coefficients are weaker.
Uniform LSI for the canonical ensemble on the 1D-lattice with strong, finite-range interaction
Authors: Kwon Younghak , Menz Georg
Published: March 2020

We consider a one-dimensional lattice system of unbounded, real-valued spins with arbitrary strong, quadratic, finite-range interaction. We show that the canonical ensemble (ce) satisfies a uniform logarithmic Sobolev inequality (LSI). The LSI constant is uniform in the boundary data, the external field and scales optimally in the system size. This extends a classical result of H.T. Yau from discrete to unbounded, real-valued spins. It also extends prior results of Landim et al. or Menz for unbounded, real-valued spins from absent- or weak- to strong-interaction. We deduce the LSI by combining two competing methods, the two-scale approach and the Zegarlinski method. Main ingredients are the strict convexity of the coarse-grained Hamiltonian, the equivalence of ensembles and the decay of correlations in the ce.
On the excursion area of perturbed Gaussian fields
Authors: Di Bernardino Elena , Estrade Anne , Rossi Maurizia
Published: March 2020

We investigate Lipschitz-Killing curvatures for excursion sets of random fields on ℝ2under a very specific perturbation, namely a small spatial-invariant random perturbation with zero mean. An expansion formula for mean curvatures is derived when the magnitude of the perturbation vanishes, which recovers the Gaussian Kinematic Formula at the limit by contiguity of the model. We develop an asymptotic study of the perturbed excursion area behaviour that leads to a quantitative non-Gaussian limit theorem, in Wasserstein distance, for fixed small perturbations and growing domain. When letting both the perturbation vanish and the domain grow, a standard Central Limit Theorem follows. Taking advantage of these results, we propose an estimator for the perturbation variance which turns out to be asymptotically normal and unbiased, allowing to make inference through sparse information on the field.
About the Stein equation for the generalized inverse Gaussian and Kummer distributions
Authors: Konzou Essomanda , Koudou Angelo Efoevi
Published: March 2020

We observe that the density of the Kummer distribution satisfies a certain differential equation, leading to a Stein characterization of this distribution and to a solution of the related Stein equation. A bound is derived for the solution and for its first and second derivatives. To provide a bound for the solution we partly use the same framework as in Gaunt 2017 [Stein, ESAIM: PS 21 (2017) 303–316] in the case of the generalized inverse Gaussian distribution, which we revisit by correcting a minor error. We also bound the first and second derivatives of the Stein equation in the latter case.
Komorbidität von Hypoglykämieangst und Panikstörung bei einer Patientin mit Typ-1-Diabetes – Kombinationsbehandlung mit Verhaltenstherapie und kontinuierlicher Glukosemessung (CGM) in einer psychosomatischen Tagesklinik
Authors: Pontow Inga-Marlen , Theil Jan , Diefenbacher Albert
Published: March 2020

Anamnese und klinischer Befund Eine Patientin mit T1DM, Panikstörung und Hypoglykämieangst (Diabetesdauer 4 Jahre, BMI 25,6) wurde in der Tagesklinik Psychosomatik mit einem multimodalen Behandlungsansatz behandelt. Sie berichtet von ausgeprägter Angst vor Hypoglykämie und von wiederholten Hypoglykämien. Aus Angst vor Hypoglykämien veränderte die Patientin ihr Diabetes-Selbstmanagement und erlebte damit Einschränkungen in ihrer Alltagsfunktionalität.

Untersuchung Nach Aufnahme wurde bei der Patientin kein Blutzuckerwert unter 3,7 mmol/l (70 mg/dl) gemessen, allerdings zeigten sich Symptome einer leichten Hypoglykämie schon bei Blutzuckerwerten im unteren Normbereich. HbA1c bei Aufnahme bei 54 mmol/mol, 7,1 %.

Diagnosen Diabetes mellitus Typ 1, Panikstörung und übersteigerte Angst vor Hypoglykämien.

Therapie und Verlauf Kombination aus kontinuierlicher Glukosemessung (CGM) und Beschwerdeprotokollen als Methode der kognitiven Verhaltenstherapie (KVT) in Ergänzung zu einem multimodalen Akzeptanz- und Commitment-Therapie (ACT)-basierten Gruppenpsychotherapieprogramm. Dies führte zur Verbesserung der Symptomdiskrimination und zur Reduktion von Sicherheits- und Vermeidungsverhalten.

Folgerung Die Kombination von psychotherapeutischen Maßnahmen mit CGM erscheint als hilfreicher Ansatz zur Behandlung krankheitsspezifischer psychischer Störungen bei Diabetes mellitus.
Häufigkeit eines Risikos für Mangelernährung bei Patienten in onkologischen Schwerpunktpraxen – eine Querschnittserhebung
Authors: Hauner Hans , Kocsis Alexandra , Jaeckel Benjamin , Martignoni Marc , Hauner Dagmar , Holzapfel Christina
Published: March 2020

Hintergrund Daten zum Ernährungsstatus von Patienten mit Tumorerkrankungen in ambulanten Einrichtungen fehlen in Deutschland. Die durchgeführte Querschnittserhebung bei Patienten mit Tumorerkrankungen hatte daher das Ziel, die Häufigkeit eines Risikos für Mangelernährung bei Tumorpatienten in onkologischen Schwerpunktpraxen zu ermitteln.

Methode Patienten mit Tumorerkrankungen wurden mittels eines standardisierten Fragebogens konsekutiv in 17 onkologischen Schwerpunktpraxen in Südbayern zwischen Juni 2017 und Mai 2018 befragt. Neben Fragen zum Gesundheitszustand und zur Ernährung wurden die validierten Screening-Fragebögen Malnutrition Universal Screening Tool (MUST) und Nutritional Risk Screening Tool-2002 (NRS-2002) zur Erfassung des Risikos für Mangelernährung (primärer Endpunkt) eingesetzt. Die statistische Auswertung erfolgte deskriptiv.

Ergebnisse Insgesamt wurden Datensätze von 765 Patienten (60,9 % Frauen) ausgewertet. Die Teilnehmer waren im Mittel 63,1 ± 13,1 Jahre alt, der durchschnittliche Body-Mass-Index (BMI) betrug 25,2 ± 5,1 kg/m2. Bei Anwendung des MUST-Fragebogens hatten 15,4 % der Teilnehmer ein mittleres und 19,5 % ein hohes Risiko für eine Mangelernährung. Darunter wiesen am häufigsten Patienten mit Tumoren des Verdauungssystems ein Risiko für eine Mangelernährung auf (46,6 %). Die Kriterien für ein Mangelernährungsrisiko nach dem NRS-2002-Score (≥ 3 Punkte) erfüllten hingegen 29,1 % der befragten Patienten. Weniger als ein Drittel der Tumorpatienten hatte nach Diagnosestellung eine Ernährungsberatung erhalten (29,9 %).

Schlussfolgerung Etwa jeder dritte Patient mit einer Tumorerkrankung in ambulanter Betreuung weist ein erhöhtes Risiko für eine Mangelernährung auf. Die Ergebnisse dieser Erhebung unterstreichen die Notwendigkeit für ein systematisches Screening auf Mangelernährung und ein leitliniengerechtes Ernährungsmanagement von Tumorpatienten in der ambulanten Versorgung.

Published: March 2020

Objetivo Avaliar os benefícios clínicos e radiológicos do uso do ácido hialurônico exógeno intra-articular para o tratamento da lesão condral da patela.

Método Ensaio clínico randomizado com 70 pacientes divididos em dois grupos: o de tratamento fisioterápico por 3 meses, e o de tratamento fisioterápico associado à aplicação de 2 ml de ácido hialurônico intra-articular pelo mesmo período, composto por pacientes com dor na região anterior do joelho e lesão de graus II ou III da cartilagem da patela, sem anormalidades ósseas significativas. Foram avaliados os escores funcionais e as características do exame físico e de imagem antes, e após 3 e 6 meses de tratamento.

Resultado A idade média dos pacientes foi de 32 ± 7,6 anos. Os pacientes do grupo submetido à aplicação de acido hialurônico apresentaram melhores escores de Kujala et al e de Lysholm, e menor pontuação de dor após 3 e 6 meses de tratamento quando comparados ao grupo controle.

The study was conducted to assess the effect of ambulation and birthing ball on the maternal and newborn outcome from 01.08.2011 to 31.10.2011. This randomized control study was conducted on 60 primigravida mothers. Purposive sampling technique was used for the selection of samples followed by random allocation of 20 samples each to the three groups namely, ambulation, birthing ball and control group respectively using lottery method. Ambulation and birthing ball therapy were given to the respective samples between cervical dilatation of 1-3cm during first stage of labour, whereas the control group was not given any intervention. Here maternal outcome includes1st stage duration (Area1), 2nd stage duration (Area2), cervical dilatation rate (Area3), and type of delivery(Area4) and newborn outcome includes heart rate, respiratory rate, colour, reflex and muscle tone. Since the t calculated value in Area 1 (5.257), Area 2 (2.781), Area 3(5.438) is greater than t table value (2.042) and in Area 4, 75% of ambulation group underwent normal vaginal delivery, it shows that there is significant improvement in maternal outcome after the use of ambulation. The t calculated value in Area 1(7.223), Area 2 (5.556), Area 3(6.178) is greater than t table value (2.030) and in Area 4, 95% of birthing ball group underwent normal vaginal delivery. It shows that there is significant improvement in maternal outcome after the use of birthing ball therapy. Comparison of ambulation and birthing ball therapy on maternal outcome showed that, there is significant difference in second stage duration (t tab 2.031(df=36)< t cal 2.231= S) and type of delivery. In this study ambulation and birthing ball were found to be effective to improve maternal outcome and there was no harm to the baby. Both the experimental group mothers expressed that they were satisfied and comfortable.

Published: March 2020

The aim of the present study is to evaluate the status of serum nitric oxide and arginase activity in oral cancerous condition. The study consisted of 80 individuals. The subjects were divided into normal individuals and individuals with oral cancer. Blood sample was collected from each subject and serum separated. Nitric oxide concentration was measured as total nitrates and nitrites by the Griess reaction method and arginase activity was estimated by diacetylmonoxime method.

The results of this study showed significantly increased levels of nitric oxide and arginase activity in oral cancerous condition when compared to normal individuals. From the study it can be concluded that during carcinogenesis and tumor progression, the level of nitric oxide and arginase activity increases. This could result from a generalized increased nitric oxide synthesis throughout the body of the cancer patient or reflect increased nitric oxide degradation promoted by oxidative stress.
KNUCKLE-WALKING: PRELUDE TO HOMININ BIPEDALTY OR ACQUIRED MECHANISM TO PROTECT FINGERTIPS?
Authors: Kumar Arunachalam
Published: March 2020

The exact period, cause and evolution of erect posture and bipedal gait in early hominids has subject of much debate among primatologists and anthropologists. This brief presentation proposes at least that one among the theories, knuckle-walking as a precursor to bipdality is probably debatable. In higher apes, which spend more time on foraging at terrestrial level and less as arboreal primates, knuckle walking may have evolved more as a nail and fingertip protective adaptation in apes.
BILATERAL OSSIFIED STYLOHYOID CHAIN - A CASE STUDY
Authors: H. Shivarama C. , Shivarama Bhat , K. Radhakrishna Shetty , S. Vikram , R. Avadhani
Published: March 2020

The styloid process is a slender bony projection that arises from the inferior surface of the temporal bone just beneath the external auditory meatus and closely related to the stylomastoid foramen. The normal length of SP in an adult is considered to be 20 to 30mm however, it is very variably developed, ranging in length from a few millimetres to a few centimetres.

The styloid process is developed at the cranial end of cartilage in the second visceral or hyoid arch by two centers: a proximal, for the tympanohyal, appearing before birth; the other, for the distal stylohyal, after birth. But sometimes the stylohyoid chain may form, that extends between the temporal and hyoid bones which are divided into 4 sections: tympanohyal, stylohyal, ceratohyal and hypohyal. Cartilage that is embryo logically located at the stylohyoid ligament may undergo calcification of varying degrees, which causes variations. Ossified stylohyal ligament parts may merge or leave gaps in between. The anatomy of styloid process has immense embryological, clinical, surgical importance.

Peeling of Dirac field on Kerr spacetime
Authors: Truong Xuan Pham
Published: March 2020

In a recent paper with Nicolas [Ann. Henri Poincaré 20(10), 3419–3470 (2019); arXiv:1801.08996], we studied the peeling for scalar fields on Kerr metrics. The present work extends these results to Dirac fields on the same geometrical background. We follow the approach initiated by Mason and Nicolas [J. Inst. Math. Jussieu 8(1), 179–208 (2009); arXiv:gr-qc/0701049 and L. Mason and J.-P. Nicolas, J. Geom. Phys. 62(4), 867–889 (2012); arXiv:1101.4333] on the Schwarzschild spacetime and extended to Kerr metrics for scalar fields. The method combines the Penrose conformal compactification and geometric energy estimates in order to work out a definition of peeling at all orders in terms of Sobolev regularity near I, instead of Ck regularity at I, and then provides the optimal spaces of initial data such that the associated solution satisfies peeling at a given order. The results confirm that the analogous decay and regularity assumptions on initial data in the Minkowski and Kerr spacetimes produce the same regularity across null infinity. Our results are local near spacelike infinity and are valid for all values of the angular momentum of the spacetime, including for fast Kerr metrics.
Micromechanical modeling and calculation for diffraction elastic constants of Ni-based superalloy
Authors: Liu Li , Chen Qiang , Zhu Changjun , Chen Kanghua
Published: March 2020

A micromechanical model for Ni-based superalloys with reinforcement γ′-Ni3(AlTi) was established to investigate the elastic modulus related to crystallographic directions. In this model, grains were assumed to have spheroidal random dispersion, and the interface of matrix and inclusion phases with lattice strain and macroscopic stress being assumed were straightforwardly converted. Introducing a representative volume element, a series of micromechanical averaged field equations administrating diffraction elastic constants of the γ-(Ni–Cr–Fe) matrix phase and the γ′-Ni3(AlTi) dispersed particulate phase are presented to render qualitative and quantitative analysis in terms of scale transition formalism, respectively. Following the content of the micromechanical framework, the effective elastic properties of Ni-based superalloys were predicted. Furthermore, the numerical diffraction elastic constants of several diffraction planes were compared with those of experimental determination by neutron diffraction, whose implications of diffraction elastic constants required for experimental measurement of residual stresses were discussed.
Dichalcogenide Landau miniband dynamics and spectrum in an antidot superlattice
Authors: Morgenstern Horing Norman J.
Published: March 2020

This work addresses the dynamics of carriers in the Group VI dichalcogenides in a quantizing magnetic field with a model anti-dot superlattice in the system. The Green’s function describing the quantum dynamical development along the axis of the lattice is determined explicitly in terms of the known “no-lattice” dichalcogenide Green’s function subject to Landau quantization. The associated eigen-energy dispersion relation is formulated and approximately solved for weak lattice coupling, explicitly tracing the formation of Landau minibands in the spectrum of “relativistic” dichalcogenide carriers in a normal, quantizing magnetic field.

We report the synthesis and characterization of a new ternary molybdenum pnictide superconductor, Cs2Mo3As3. The powder x-ray diffraction analysis reveals the quasi-one-dimensional (Q1D) hexagonal crystal structure formed by Cs+ and infinite (Mo3As3)2− chains as indicated by the wire-like grain morphology. Electrical resistivity and magnetic susceptibility characterizations exhibit superconductivity with the onset transition temperature at 11.5 K, which is the highest in all Q1D superconductors reported so far. An upper critical magnetic field of about 61.7 T at zero temperature was extrapolated from the resistivity measurement under a magnetic field, which is much higher than the Pauli paramagnetic limit, and the reason for such a high upper critical field may lie in its unconventional nature of superconducting pairing symmetry. The discovery of Cs2Mo3As3 inspires the search for new superconductors for future high field applications.
Laser Raman scattering by graphene plasmons
Authors: Kumar Pawan
Published: March 2020

A new scheme of Raman scattering of a laser by THz graphene plasmons in the presence of both space charge and electromagnetic surface plasmons is proposed. Plasmon–laser coupling arises through the two dimensional response of electrons in graphene. For optical frequency laser scattering by THz plasmons, phase matching conditions are satisfied for near normal incidence and the Raman scattered wave also propagates normal to the graphene surface. The amplitude of the electric field of the Raman scattered wave scales linearly with the plasmon density fluctuation level and laser amplitude and inversely with the electron effective mass. Raman scattering would provide in situ diagnostics of the amplitude and frequency of the THz wave.
An experimental study on the blinking suppression mechanism of organic-inorganic formamidinium lead halide perovskite quantum dots on N-Type semiconductors

Published: March 2020

Lead halide perovskite has emerged as a potential material for a wide range of applications, including solar cells, light-emitting diode displays, lasing, and single photon emitters. To optimize their utilization in optoelectronic devices, the fundamental photophysical properties, especially their charge carrier transition and blinking behaviors, must be elucidated. In this study, we investigate the blinking behaviors of single formamidinium bromide perovskite quantum dots (FAPbBr3 PQDs) on the n-type TiO2 substrate. It is suggested that the electrons from TiO2 fill the trap states of FAPbBr3 PQD during Fermi-level equilibrium, which can reduce the possibility of capturing the hot electrons from PQD into the trap states. In addition, charge separation and charge recombination processes between PQD and TiO2 are expected to shorten the duration of the OFF state, thus stabilizing the fluorescence of PQDs.
Metal–organic chemical vapor deposition of 2D van der Waals materials—The
challenges and the extensive future opportunities
Authors: Lee Do Hee , Sim Yeoseon , Wang Jaewon , Kwon Soon-Yong
Published: March 2020

The last decade has witnessed significant progress in two-dimensional van der Waals (2D vdW) materials research; however, a number of challenges remain for their practical applications. The most significant challenge for 2D vdW materials is the control of the early stages of nucleation and growth of the material on preferred surfaces to eventually create large grains with digital thickness controllability, which will enable their incorporation into high-performance electronic and optoelectronic devices. This Perspective discusses the technical challenges to be overcome in the metal–organic chemical vapor deposition (MOCVD) growth of 2D group 6 transition metal dichalcogenide (TMD) atomic crystals and their heterostructures, as well as future research aspects in vdW epitaxy for 2D TMDs via MOCVD. In addition, we encourage the traditional MOCVD community to apply their expertise in the field of “2D vdW materials,” which will continue to grow at an exponential rate.
Understanding the reproductive biology of Terminalia ferdinandiana for improved fruit yields
Authors: Gorman Julian , Markones Hanna , Lawes Michael John
Published: March 2020

Terminalia ferdinandiana Exell., also known as the Kakadu plum, is an important food plant endemic to northern Australia. The fruit has substantial commercial demand as it contains sought-after antioxidants and the greatest concentration of ascorbic acid of any fruit known worldwide. Better knowledge of its reproductive biology is required to increase fruit production from wild stands and sustain commercial demand. Experiments demonstrate that T. ferdinandiana is andromonoecious and self-incompatible, relying on cross-pollination for successful fruit production. Wild stocks of this species are pollen limited, likely caused by pollinator satiation in dense, synchronously flowering stands. These findings indicate that enhanced fruit production requires supplementation of suitable pollinators in wild stands.
