title: Establishment of in vitro aseptic culture of Philodendron xanadu Croat

description: ABSTRACT The philodendron is a plant with a high sales price, however, in Mexico there is not enough plant material available for the producers of this ornamental. Therefore, the objective of this research was to establish an in vitro aseptic culture of philodendron, for this, the effect of fungicides and bactericides applied from the transplantation of mother plants to the production and harvest of explants (axillary shoots) for in vitro establishment was evaluated. Two experiments were carried out using MS culture medium; in the second, silver nanoparticles (AgNPs) were added to the culture medium. Both experiments were established in a completely randomized experimental design. It was observed that with the joint action of the sanitizing products in the treatment of mother plants and in the disinfection process, as well as the addition of AgNPs to the culture medium, it was possible to establish an aseptic culture of philodendron. Results show that 2 g L-1 of Agry-Gent Plus 5000® plus 2 g L-1 of Prozycar® in the treatment of mother plants was the one generated the highest percentage of aseptic explants (25.71%) in the first in vitro establishment, while, in the second experiment, the same products plus the addition of AgNPs to the culture medium for seven days generated 100% aseptic explants. The contaminants identified were yeasts, Aspergillus sp. and Penicillium sp.

title: Supplementary Material for: The association between surgical patient selection and hospital variation in failure to cure in esophageal cancer surgery. A nation-wide cohort study.

description: Introduction; Failure to cure describes: 1)non-resectional(‘open-close’) surgery, 2)non-radical surgery(R1-R2) and/or 3)postoperative mortality. This study aims to investigate whether hospitals offering surgery to a large proportion of patients have higher failure-to-cure rates than hospitals operating fewer patients. Methods; From the Netherlands Cancer Registry, all cT1-cT4a/cTx-any cN-cM0 esophageal cancer patients diagnosed in 2015-2018 were included. For each center, the expected(E) proportion of patients undergoing surgery was established and divided by the observed(O) proportion. Hospitals were categorized into three groups: 1. hospitals treating relatively many patients with surgery, 2. average hospitals and 3. hospitals treating relatively few patients with surgery. Multilevel multivariable regression investigated the association between these hospital groups and failure to cure. Results; Some 3,437(53.2%) of 6,457 patients underwent surgery, ranging from 45-64% among 16 hospitals. The failure-to-cure rate was 15.0%(hospital variation[4.6-23.7%]). After categorizing, 1,003 patients underwent surgery in hospitals with low surgery rates (O/E ratio&lt;0.94/corrected percentage&lt;50%), 1,297 patients in average hospitals and 1,137 patients in hospitals treating many patients surgically (O/E ratio&gt;1.01/corrected percentage&gt;54%). Failure-to-cure rates were 16.8%, 12.2% and 14.0%, respectively. This was non-significant in multilevel analyses (aOR:0.63, 95%CI:0.38-1.05; aOR:0.76, 95%CI:0.46-1.24). Discussion/Conclusion; Failure-to-cure rates were similar in hospitals with a high surgery rate and hospitals with a low rate. Increasing the proportion of patients undergoing a resection may offer more patients a chance for cure.

title: Cereal bar enriched with cowpea bean whole flour, cashew nut, and raisin banana

description: ABSTRACT This work aimed to elaborate a cereal bar with whole cowpea flour, cashew nuts and bananas raisin and evaluate their acceptance and chemical composition. Three formulations were developed, B1 with 5.25% cowpea, B2 7.5% and B3 with 15%. Sensory attributes were assessed by 10 trained tasters using a hedonic scale. Two formulations were analyzed by 100 untrained tasters using the multiple comparison, paired comparison and purchase intention tests. The humidity was determined by drying in an oven and the ashes after calcination of the samples in a muffle furnace. The protein content was obtained by the Macro-Kjeldahl method and the lipid content by hot extraction in a Soxhlet apparatus. Carbohydrates were determined by difference and minerals by the technique of atomic emission spectrometry with inductively coupled plasma source. After testing with the trained team, it was observed that the B3 bar received the lowest average in relation to flavor. With untrained tasters, it was found that bars B1 and B2 are commercially viable and showed no difference in the paired comparison. The increase in cowpea promoted an increase in the levels of ash, lipids and proteins. Bar B2 showed the highest content of ash, lipids and proteins and the lowest amount of carbohydrates and moisture. The bars presented themselves as sources of iron, phosphorus, magnesium and zinc and with a high content of copper and manganese. It is concluded that the elaborated cereal bar contains high nutrients content and has sensory viability.

title: Regression analysis to evaluate herbicide drift and injury in Roundup Ready cotton in wind tunnel

description: ABSTRACT The aim was: (i) to propose a regression model for the association between injury in Roundup Ready (RR) cotton plants and drift of auxins, isolated or associated with glyphosate; (ii) to evaluate the effect of adding glyphosate to dicamba and 2,4-D auxinic herbicides on the physicochemical properties of the spray solutions; and (iii) to validate the wind tunnel as a tool to perform herbicide injury prediction. Three experiments were conducted using the following spray solutions: glyphosate (0.225 kg a.e. ha-1); dicamba (0.120 kg a.e. ha-1); 2,4-D (0.168 kg a.e. ha-1); glyphosate + dicamba (0.225 + 0.120 kg a.e. ha -1) and glyphosate + 2,4-D (0.225 + 0.168 kg a.e. ha-1). Experiment I assessed drift in wind tunnel at distances of 5, 10 and 15 m from the nozzle spray drift. Experiment II assessed injury on cotton plants arranged at the same distances as in experiment I. Experiment III studied the physicochemical characteristics of the spray solutions used in experiment I, assessing surface tension, pH and density. The collected drift and injury are directly proportional, following a simple linear regression model, with increased drift and injury potential at 5 m from the sprayer. The addition of glyphosate to 2,4-D and dicamba herbicides reduced surface tension and pH of the spray solutions. The wind tunnel, besides evaluating drift potential, was found to be an alternative for the prediction of injury in RR cotton plants.

title: Modelling chlorophyll-a concentrations in a continental aquatic ecosystem of the Brazilian semi-arid region based on remote sensing

description: ABSTRACT Remote-sensing data are essential to evaluate dynamic processes such as eutrophication and increases in the concentration of suspended sediments in continental aquatic systems. The aim of this study, therefore, was to develop models to estimate chlorophyll-a concentrations from remote-sensing data in continental waters of the Brazilian semi-arid region. The study area corresponds to the Orós reservoir, located in the state of Ceará. The models were developed based on measurements taken at 20 sampling points. Water samples were collected from the reservoir to i) analyse the chlorophyll-a, electrical conductivity, pH and turbidity; ii) take optical measurements in situ of water transparency and spectral radiance. Radiance measurements were carried out using an ASD FieldSpec®3 Hi-Res spectroradiometer. The spectral data were later transformed into reflectance values and used to test the performance of several models found in the literature for estimating chlorophyll-a. The results showed that for the three-band model, the maximum value for the coefficient of determination (R2), of 0.88, was obtained using the λ1 = 660 nm, λ2 = 690 nm and λ3 = 717 nm spectral bands. The model employing two spectral bands presented the best performance (R2 = 0.87) in the λ1 = 660 nm and λ2 = 690 nm bands. An absolute mean error of 5.35 and 5.00 µg L-1 was found for the three- and two-band models respectively. The developed models are reliable, showing that chlorophyll-a concentrations can be quantified from remote-sensing field data with a high degree of accuracy.

title: Inheritance of hydrogen potential (pH) and titratable acidity in the melon

description: ABSTRACT Acidity is one of the main determinants of the taste and quality of melon fruit, together with sugars and volatile compounds. The aim of this study was to investigate the inheritance of hydrogen potential (pH) and titratable acidity in melon fruit. A randomized block design with three replications was used to evaluate the F1 and F2 generations and backcrosses (RC1 and RC2) of the Védrantais melon (Cucumis melo subsp. melo var. reticulatus) with high pH and low titratable acidity, and of the AC-16 melon (C. melo subsp. melo var acidulus), with low pH and high titratable acidity. Inheritance of pH and titratable acidity in the melon is complex, and each involves a major gene with additive and dominance effects associated with polygenes with additive effects.

title: Selectivity of essential oils to the egg parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)

description: ABSTRACT The diversity of arthropod pests has required the combined use of various control methods. The application of essential oils showing insecticidal, repellent or phage-inhibiting activity, together with the release of natural enemies, can improve integrated pest management provided the oils display selectivity. The aim of this study was to evaluate the selectivity of the oils of rosemary pepper [Lippia origanoides Kunth (Verbenaceae)], citronella [Cymbopogon winterianus Jowitt. (Poaceae)] and lemongrass [C. citratus (DC) Stapf.] for Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae), comparing five concentrations (0.01, 0.05, 0.1, 0.5 and 1.0%), and a control (neutral detergent at 1.0%). Residual toxicity was evaluated using adult mortality, calculating lethal concentrations (LC50) in addition to the reductions in parasitism in eggs of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and selectivity for the par asitoids. The three oils showed selectivity for the parasitoid T. pretiosum, resulting in a mortality rate of between 17.2% (rosemary pepper) and 32.2% (lemongrass) at the lowest concentration. The essential oil of rosemary pepper stood out with an LC50 of 0.43%, a reduction of only 22% in parasitism (Class 1 - Innocuous) and 88.0% emergence, at a dose of 0.01%. The LC50 of the lemongrass oil was 0.15%, with a 34.0% reduction in parasitism (Class 2 - Slightly harmful) and 74.0% emerged adults. For the citronella oil, the LC50 was 0.12%, with a reduction of 46.0% (Class 2 - Slightly harmful) and emergence of 62.0%. The selectivity of the essential oils makes possible to release T. pretiosum, integrating biological control with botanical insecticides, as long as non-sprayed eggs are parasitised by T. pretiosum.

title: Indication of cowpea cultivars for the production of dry grain in the state of Ceará

description: ABSTRACT The aim of this work was to evaluate the interaction between genotypes and environments, as well as to indicate, for the state of Ceará, superior cowpea cultivars in terms of adaptability, stability and productivity of dry grains. The experiments were conducted in four different municipalities in the state of Ceará: Crateús, Madalena, Bela Cruz and Limoeiro do Norte; two tests carried out in Crateús (irrigated and rainfed), totaling five assessment environments. The experimental design used in each assay was randomized blocks with 12 genotypes and four replications. Analysis of variance and path analysis were performed, and the averages of the quantitative characters were grouped by the Scott-Knott test. After detecting the significance of the genotype x environment interaction, the adaptability and phenotypic stability of the genotypes were analyzed using the GGE biplot methodology. The municipality of Crateús, in the irrigated system, was discriminative and representative, and can be considered ideal for genotype evaluation. The cultivars BRS Pajeú and BRS Potengi can be recommended for cultivation in the state of Ceará due to their high productivity of dry grains, adaptability and stability, and for having excelled in most of the production components. The number of pods per plant had the greatest direct effect on grain yield.
