Some abnormal growth phenotypes including hybrid necrosis are often observed in F1 hybrids (genome constitution, ABD, 2n=21) and synthetic hexaploid wheat lines (AABBDD, 2n=42) which were artificially produced by crossing between tetraploid wheat (AABB, 2n=28) and Ae. tauschii (DD, 2n=14). The hybrid necrosis phenotypes are generally divided into type I and type II necrosis. In the hybrid plant...
Construction of high-resolution genetic maps is important for genetic and genomic research, as well as for molecular breeding. Single nucleotide polymorphisms (SNPs) are the predominant class of genetic variation and can be used as molecular markers. Aegilops tauschii, the D-genome donor of common wheat, is considered a valuable genetic resource for wheat improvement. Our previous study implied...
this study was carried out to investigate the effects of integrative vs. instrumental motivation, learning strategy use and gender on iranian efl learners. to this end, 120 efl learners both male and female majoring in english language and literature at shiraz university participated in the study. in order to conduct this study three instruments were used: oxford quick placement test, motivatio...

abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
به‌منظور بررسی تأثیر کود فسفر و محلول‌پاشی کلات آهن بر میزان جذب عناصر کم‌مصرف، میزان پرولین و کربوهیدرات‌های محلول در مراحل رشدی مختلف در رقم سرداری (گندم نان) و گونه‌های اجدادی آن در شرایط دیم، در آزمایشی فاکتوریل با 3 عامل شامل: کود فسفر (در 2 سطح)، محلول‌پاشی کلات آهن (در 2 سطح) و گونه‌های مختلف گندم در 5 سطح (رقم سرداری، Triticum boeoticum، Aegilops speltoides، Triticum diccocoides و Aegil...
Studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. Chromosome staining of immature and adult pollen grains through conventional acetocarmine procedure is tedious and often leads to unsatisfactory results. An acetocarmine stain, used in conjugation with Carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike be...
