به منظور بررسی تاثیر شوری خاک بر برخی از ارقام گیاه پنبه و مشخص نمودن ارقام متحمل در استان گلستان (در ایستگاه تحقیقات انبارالعلوم) طی دو سال ۱۳۹۱ و ۱۳۹۲ آزمایشی به صورت فاکتوریل در قالب طرح بلوک های کامل تصادفی با سه تکرار انجام شد. دوازده ژنوتیپ مورد بررسی شامل: ساحل، گلستان، چکوروبا، سیلند، تابلادیلا، اوپال، ۴۳۲۰۰، سپید، سوپراکرا،q28 ، har و شیرپان ۵۳۹ و شوری (nacl) با هدایت الکتریکی ۱۶/۵ دسی...
پنبه (Gossypiuym hirsutum L.) یکی از مهمترین محصولات زراعی در سراسر دنیاست. ارقام مختلف این گیاه نسبت به شوری خاک واکنش‌های متفاوت نشان می‌دهند. به منظور بررسی اثر تنش شوری بر خصوصیات فیزیولوژیک ارقام مختلف پنبه آزمایشی در قالب طرح بلوک‌های تصادفی در سه تکرار در منطقه آق قلا (گرگان) و کارکنده (کردکوی) در سال زراعی 1389 انجام گرفت. تیمارهای مورد بررسی شامل ژنوتیپ‌های پنبه در 10 سطح (ساح...
In order to examine the impact of different levels of salinity on yield and germination of 40 cultivars and local populations of cotton in greenhouse and field experiments were conducted at Rodasht Agricultural Research Station - Isfahan. In greenhouse experiments using a completely randomized design with three replications, effect of water with a salinity of 9 dS m-1 on germination rate and pe...
BACKGROUND AND AIMS Gossypium is an economically important, globally distributed taxon comprising more than 50 species. DNA content estimates from about half of the species indicate over a 3-fold variation exists. However, the nine DNA content estimates for G. hirsutum reveal over a 2-fold difference for this species alone. Recent reports have shown that several plant compounds can bias DNA con...
agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...
CLCuD in southern Asia is caused by a complex of multiple begomoviruses (whitefly transmitted, single-stranded [ss]DNA viruses) in association with a specific ssDNA satellite; Cotton leaf curl Multan betasatellite (CLCuMuB). A further single ssDNA molecule, for which the collective name alphasatellites has been proposed, is also frequently associated with begomovirus-betasatellite complexes. Mu...
Among the seven tetraploid cotton species, little is known about transmission genetics and genome organization in Gossypium mustelinum, the species most distant from the source of most cultivated cotton, G. hirsutum In this research, an F2 population was developed from an interspecific cross between G. hirsutum and G. mustelinum (HM). A genetic linkage map was constructed mainly using simple se...
BACKGROUND Upland cotton, Gossypium hirsutum L., is one of the world's most important economic crops. In the absence of the entire genomic sequence, a large number of expressed sequence tag (EST) resources of upland cotton have been generated and used in several studies. However, information about the flower development of this species is rare. METHODOLOGY/PRINCIPAL FINDINGS To clarify the mo...
