asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
The aim of this study was to use multiple DNA markers for detection of QTLs related to resistance to white mold in an F2 population of common bean evaluated by the straw test method. The DNA from 186 F2 plants and from the parents was extracted for genotypic evaluation using SSR, AFLP, and SRAP markers. For phenotypic analysis, 186 F2:4 progenies and ten lines were evaluated, in a 14 × 14 tripl...
As the ancestor of cultivated grape, Vitis vinifera subsp. sylvestris represents a unique, invaluable genetic resource for the improvement of cultivated grapevines. Recently, five populations of wild grapevines were identified in Portugal. Sixty vines were characterized with 11 nuclear SSR markers and further compared with 70 genotypes of Portuguese Vitis vinifera subsp. sativa. The obtained da...
در طول دهه اخیرتعداد زیادی qtl برای صفات زراعی سویا توسط گروههای تحقیقاتی مختلف به ثبت رسیده است. به دلیل اثرات متقابل بین qtlها، محیط و زمینه ژنتیکی در ظهور آنها، تائید نتایج بررسی های گذشته و نیز شناسائی qtlهای جدید نیاز به بررسیهای بیشتری دارد. به منظور نقشهیابیqtlهای کنترلکننده برخی صفات زراعی، جمعیتی شامل 140 تک بوته f2 از تلاقی rgr-jap×williams82 توسط 17 نشانگر ssr و 70 نشانگر aflp تع...
mutation induction is considered as an effective way to enrich plant genetic variation, particularly fortraits with a very low level of genetic variation. this research was conducted to assess genetic variationinduced by gamma radiation in m2 and m3 mutant lines of canola (brassica napus l.) by ssr and morphologicalcharacteristics and to identify useful mutants in terms of agronomic traits. six...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
in this research work, genetic diversity of 21 wild persian shallot (allium hirtifolium boiss.) accessions from south, southwest, west and center of iran was evaluated using morphological traits as well as aflp markers. results showed that khansar accession had the highest leaf width (5.42 cm), mean leaf number per plant (5.41), bulb diameter (10.84 cm), bulb height (4.95 cm) and mean bulb weig...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
