this research was conducted to investigate genotyp×environment interaction for grain yield of ten wheat cultivars in 8 environments (combinations of two nitrogen fertilizer treatment and four irrigation regimes). analysis of additive main effects (analysis of variance) and multiplicative interaction effects (principal component analysis) revealed that the effects of genotype, environment and ge...
fusarium head blight (fhb) caused by fusarium graminearum is responsible for billions of dollars in agriculture losses. the goal of the present study was evaluation the expression of acidic chitinase, one of pr proteins, in wheat defense response against different fhb induced treatments in 'falat' as a highly susceptible and 'sumai3' as a tolerant cultivar. these treatments contained fungi extr...
in order to develop molecular markers based on expressed sequence tag (est) linked to fusarium head blight (fhb) resistance genes in wheat, the biological function of 8660 ests deposited in data bank were studied following which 260 ests with identified biological function were selected. in total, 62 primer combinations were designed based on conserved and non conserved sequences. linkage and q...
تنش شوری فرایند های فیزیولوژیکی متعددی را در گیاهان تحت تاثیر قرار می دهد، برخی از این آثار شامل آسیب اکسیداتیو اجزای سلولی می باشد که توسط گونه های فعال اکسیژن ایجاد می شود. در مقابل، آنزیم های آنتی اکسیدان باعث جلوگیری از این آثار مخرب می شوند. در پژوهش حاضر به منظور مطالعه برخی صفات فیزیولوژیکی و مولکولی نظیر میزان بیان ژن کاتالاز (catalase: cat1) و آسکوربات پراکسیداز (ascorbate peroxidase:a...
One way of controlling plant response to various biotic stresses occurs through programmed cell death, this system is known as the hypersensitive reaction. Plant resistance system against stress is stimulated through different chemicals such as salicylic acid. Therfore, experiment was conducted in a completely randomized design with three replications, in order to identifying the expressed pr...
شناسایی نشانگرهای ریزماهواره پیوسته با مکانهای ژنی کمی برای مقاومت به بلایت فوزاریومی سنبله در گندم
Fusarium head blight (FHB) is one of the most destructive diseases of wheat causing significant reduction in grain yield and quality. Development of resistant varieties is an effective, economical and enviromentally safe way to control FHB disease. A major QTL (quantitative trait locus) for Fusarium head blight resistance, Qfhs.ndsu-3BS, derived from cv. Sumai 3, has been identified and verifie...
This study was conducted to evaluate the capability of reversed-phase high performance liquid chromatography (RP-HPLC) of wheat (Triticum aestivum L.) storage proteins, and their genetic variability in different winter and spring isolines, cultivars and landraces. Gliadin proteins were extracted from the flour of five randomly selected seeds of each genotype. In this method, Nucleosil C18 300 A...
به منظور بررسی سازگاری ارقام گوجه فرنگی با طول دوره رویشی کوتاه و تعیین تاریخ کاشت مناسب در منطقه سردسیر شمال استان فارس آزمایشی در مزرعه ایستگاه تحقیقات کشاورزی و منابع طبیعی اقلید اجرا شد. آزمایش در قالب بلوک های کامل تصادفی به صورت کرت های خرد شده با پانزده تیمار و سه تکرار اجرا شد. تیمار اصلی تاریخ کاشت، بیست اردیبهشت ماه، یکم خرداد ماه، دهم خرداد ماه و تیمار فرعی پنج رقم شامل: Sun 6108، Ri...
In order to study the redistribution response of photosynthetic assimilates of different spring bread wheat cultivars in different densities of wild oat, an experiment was conducted based on a strip block experiment with three replications at the Research Farm of Ramin Agriculture and Natural Resources University, Ahwaz, Iran during 2012. Treatments were four oat densities (0, 40, 80 and 120 pl...
This study was conducted in Rudasht Research Farm Isfahan, to evaluate tolerance to iron (Fe) deficiency of 30 spring wheat genotype, using split plots in a randomized complete block design with three replications. Main plot consisted of two Fe levels (0 and 20 kg Fe ha-1 applied as FeEDDHA at planting and beginning of vegetative growth). Grain yield increased by 14% following the application o...
