title: Allelopathic Effects of Invasive Prosopis juliflora on Grass Species of Potohar Plateau, Pakistan

description: ABSTRACT The present study was conducted to investigate the allelopathic effects of Prosopis juliflora (Sw.) DC. (Mesquite) on various growth parameters of three promising grass species (Cenchrus ciliaris, Panicum antidotale and Panicum maximum) on the Potohar Plateau, Pakistan, under nursery conditions. The experiment was carried out under a completely randomized design with two factors and three replicates. Different concentrations of the foliage aqueous extract of P. juliflora were prepared and their effect was studied on root length, shoot length, fresh and dry biomass of tested grass species. All grass species showed a concentration dependent inhibition. However, among all grasses, C. ciliaris was affected most severely whereas P. antidotale was the least affected grass species. This indicates an adverse effect of mesquite leaf on grass growth which is directly proportional to the increase in the extraction level of the mesquite leaf. These outcomes suggest that mesquite foliage contains allelochemicals that had inhibitory effect on grass growth.

title: Effects of Environmental Factors on Seed Germination and Emergence of Velvetleaf (Abutilon theophrasti)

description: ABSTRACT: Velvetleaf, an annual broadleaf weed, is a common and troublesome weed of cropping systems worldwide. Laboratory and field experiments were conducted to determine the effects of environmental factors on germination and emergence of velvetleaf. Seeds germinated over a range of constant temperatures from 10 to 40 oC regardless of light conditions, but no germination occurred at temperature below 5 oC and beyond 50 oC. Seeds germinated at alternating temperature regimes of 15/5 to 40/30 oC, with maximum germination (&gt;90%) at alternating temperatures of 40/30 oC. Germination was sensitive to water stress, and only 0.4% of the seeds germinated at the osmotic potential of -0.4 MPa. There was no germination at ? 0.6 MPa. Moreover, germination was reduced by saline and alkaline stresses and no germination occurred at ³ 150 mM NaCl or ³ 200 mM NaHCO3 concentrations. However, pH values from 5 to 9 had no effect on seed germination. Seedling emergence was significantly affected by burial depth and maximum emergence (78.1-85.6%) occurred at the 1-4 cm depth. The results of this study have contributed to our understanding of the germination and emergence of velvetleaf and should enhance our ability to improve control strategies in cropping systems in central China.

title: Plant spatial arrangement affects grain production from branches and stem of soybean cultivars

description: ABSTRACT Phenotypic plasticity is the ability of plants to undergo changes in morphology and yield components to adapt themselves to distinct environmental conditions. The knowledge on the changes in yield components of branches and stems at varied plant spatial arrangements needs to be updated due to recent changes in soybean production system. Thus, this study aimed to evaluate the yield components of branches and stems, as well as to assess the share of these plant parts in the total grain yield of soybean cultivars with indeterminate growth type, under different spatial arrangements. The experiment was conducted during the growing seasons of 2013/2014 and 2014/2015, under a randomized complete-block design and in a4 × 3 × 2 factorial scheme with three replications. Treatments consisted of four row spacing patterns (narrow rows, twin rows, traditional row spacing, and crossed rows), three seeding rates (150, 300, and 450 thousand viable seeds∙ha–1), and two cultivars (BMX Potência RR and BRS 359 RR). Narrow rows reduce pods and grains production in branches in relation to the traditional row spacing. The number of grains per pod of stem and of branches is not altered by the changes in plant arrangement. The increase in seeding rate reduces the number of pods per plant of branches in greater magnitude than that of stems. The rise in seeding rate results in larger thousand-grain mass both of branches and of stems, but varies with the growing season.

title: Integration of Allelopathic Crop Residues and NPK Fertilizer to Mitigate Residue-Phytotoxicity, Improve Soil Fertility and Wheat Growth under Different Moisture Conditions

description: ABSTRACT: Phytotoxic effects of allelopathic crop residues are important to trickle for their use as a source of organic amendments to improve soil fertility. In present study, through pots and two year field studies, we examined the integrated effect of allelopathic residues and NPK fertilizer treatments including T0 (control), T1 (200-150-100 kg NPK ha 1), T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1), T3 (100-75-50 kg NPK ha-1 + rice straw 4 t ha-1), T4 (mung bean straw 8 t ha-1) and T5 (rice straw 8 t ha-1) under different water regimes on soil fertility and wheat crop. Solo application of mung bean residue and rice straw caused significant inhibition of various germination and growth traits of wheat while minimal inhibition occurred when allelopathic straws were integrated with NPK fertilizer both under laboratory and field conditions, especially under 14 days of alternate wet/dry cycles. Among fertilizer treatments, mung bean residue caused a greater increase in soil organic carbon, available nitrogen and available phosphorus, while there was maximum percent increase in available potassium with T1 (200-150-100 kg NPK ha-1). Maximum increase in grain yield (30% and 33%) was achieved with T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1) during 2014-15 and 2015-16, respectively. Integration of allelopathic crop residues with inorganic fertilizers and alternate wet/dry cycles can help to reduce the possible phytotoxic effect of allelopathic residues for sustainable wheat production.

title: Development and selection of super-sweet corn genotypes (sh2) through multivariate approaches

description: ABSTRACT The aim of the present study was to investigate relations among ten traits in super-sweet corn genotypes assessed by means of simple correlation, path and canonical variable analyses, as well as to investigate the relative importance of such traits to the super-sweet corn breeding program developed at Darcy Ribeiro Northern Fluminense State University in order to develop strategies able to improve the efficiency in the selection of superior genotypes. Thus, trials comprising 3 × 6 partial diallel of super-sweet (sh2) corn were carried out, according to a short_textrandomized block design (RBD)short_text with four repetitions, in two different environments located in Northern Rio de Janeiro State, Brazil (Itaocara and Campos dos Goytacazes counties). The correlation study showed that traits such as ear diameter and useful short_textearshort_text length contributed the most to increase short_textearshort_text yield (without husk); the variable ear diameter stood out for having stronger direct effect on ear yield, as well as for presenting high heritability (0.95). The trait number of grains per ear row contributed the most to the variation between hybrids, whereas the trait useful ear length contributed the least. The canonical variables showed that the genetic backgrounds of sh2-gene donor populations had effect on recurrent populations, even after five backcrossing cycles, thus resulting in the formation of two divergent groups.

title: Effect of Glyphosate on Guineagrass Submitted to Different Soil Water Potential

description: ABSTRACT: The action of herbicides on weeds that develop under water deficit can be compromised, because the routes of penetration of hydrophilic herbicides are reduced due to the lower hydration of the cuticle in these plants. Moreover, hydrophobic compounds found in the epicuticular wax coating of plants under water stress, hinder the penetration of hydrophilic compounds. This study evaluated the control efficiency of glyphosate on guineagrass plants when submitted to different water deficits. The study was conducted in a greenhouse, and treatments were composed of guineagrass plants submitted to three soil water conditions [low water deficit (13%), intermediate water deficit (10%) and high water restriction (8%)], three doses of glyphosate (0.0, 270.0 and 540.0 g ha-1) and two phenological stages of plant development (4-6 leaves and 1-3 tillers). The water management started when plants presented two developed leaves. Visual evaluations were performed 7, 14, 21 and 35 days after the application of the herbicide; the morpho-physiological parameters of the specific leaf area, stomatal conductance and the difference between the environment temperature and the leaf temperature on the day of the herbicide application were also analyzed at the end of the study, as well as the dry matter of shoot and root. With the increase of the water restriction, there was a decrease in the analyzed morpho-physiological parameters, as well as in the dry matter accumulation of the shoot and roots of the studied plants. Plant control was more efficient when a 540 g ha-1 dose of glyphosate was applied, and when they were controlled at their vegetative stage of 1-3 tiller, and with a water management of 13%. It is possible to state that guineagrass under water restriction have less control efficacy when treated with glyphosate.

title: SHOULD PEDIATRICIANS INVESTIGATE THE SYMPTOMS OF OBSESSIVE-COMPULSIVE DISORDER IN CHILDREN WITH FEEDING DIFFICULTIES?

description: ABSTRACT Objective: To review current evidence on the relationship between obsessive-compulsive disorder and feeding difficulties. Methods: Review the Science Direct and PubMed databases between 2007 and 2017 in English, Portuguese and Spanish. The search terms, used in association, were “obsessive compulsive disorder” and “picky eating/feeding difficulty”. Cohort, case control and cross sectional studies were included that analyzed children, adolescents and/or adults of any sample size from any country in the world. Opinion articles were excluded. Results: Around 245 articles were selected, and only 4 were included in this review, according to previous criteria. Results from the studies essentially described that there is indeed a difference in “picky” behaviors between subjects with and without obsessive-compulsive disorder. Patients with obsessive-compulsive disorder tend to have exacerbated symptoms of disgust, anxiety and a higher eating behavior inflexibility score. Conclusions: Obsessive-compulsive disorder and feeding difficulties patients share common symptoms. The present study alerts health professionals who follow patients with feeding difficulties as to the importance of investigating possible psychiatric comorbidities.

title: LEIGH SYNDROME: A CASE REPORT WITH A MITOCHONDRIAL DNA MUTATION

description: ABSTRACT Objective: Leigh syndrome is a neurodegenerative disorder with an incidence of 1:40,000 live births. It presents wide clinical, biochemical, and genetic heterogeneity, but with homogenous neuropatoradiological alterations. There is no specific treatment, and the prognosis is reserved. This case report aimed familiarize health professionals with the disease. Case Description: A 16-month-hold girl who was followed in outpatient clinic due to axial hypotonia and delayed psychomotor development. Karyotype, auditory evoked potentials and ophthalmologic evaluation were normal. Evidence of hyperlactacidemia and hypocitrullinemia was detected in the patient. After performing brain magnetic resonance under anesthesia, hypotonia got worse, and the patient was hospitalized after an episode of cyanosis and apnea. The electroencephalogram showed no epileptiform activity. Neuroimaging revealed bilateral lenticular hyperintensity, especially in the putamen and in the left globus pallidus regions. Molecular analysis revealed an 8993T&gt;G (MT-ATP6) mutation in the mitochondrial DNA. Comments: Between 10 and 30% of individuals with Leigh syndrome have mitochondrial DNA mutations. The decompensation after anesthetic intercurrences is typically associated with neurological deterioration and, in this case, increased the diagnosis suspicion. It is important to alert for similar cases and to reduce invasive diagnostic tests if the diagnosis is suspected.

title: Management of Charcoal Rot of Mungbean by Two Trichoderma Species and Dry Biomass of Coronopus didymus

description: ABSTRACT: A pot experiment was carried out to check the effect of Coronopus didymus (L.) Sm. dry biomass application (1%, 2% and 3% w/w) and two species of Trichoderma (T. viride and T. aureoviride) on growth and physiology of mungbean [Vigna radiata (L.) WIlczek] under biotic stress of Macrophomina phaseolina (Tassi) Goid. Inoculation of M. phaseolina (positive control) reduced plant survival, shoot and root length as well as plant dry biomass by 22%, 52%, 61% and 64%, respectively, over the negative control (without any amendment). There was 100% plant survival in treatments with T. aureoviride alone or in combination with 1% and 2% C. didymus biomass. Likewise, T. viride in combination with 2% biomass also showed 100% plant survival. Application of 3% C. didymus biomass had a pronounced effect on crop growth resulting in 101%, 233% and 342% increase in shoot length, root length and plant biomass, respectively, over the positive control. Sole inoculation of either of the two Trichoderma spp. significantly enhanced various plant growth parameters over the positive control. In general, in combination with 2% biomass of C. didymus, both Trichodermaspp. proved to be the best choice for improving mungbean biomass under stress of M. phaseolina. Activity of denfense related enzymes viz. peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) was generally higher in treatments in which 1% C. didymus biomass was applied either alone or combined with Trichoderma spp. in M. phaseolina inoculated soil.
