DOR: 98.1000/1735-0891.1398.27.28.53.1.1576.1606 در این تحقیق تعداد 49 نمونه ژنتیکی موجود در کلکسیون یولاف بانک ژن گیاهی ملی ایران، متعلق به چهار گونه Avena barbata، A. wiestii، A. fatuaو A. sativaمورد بررسی قرار گرفتند. آزمایش به صورت مشاهده‌ای، در مزرعه پژوهشی مؤسسه تحقیقات اصلاح وتهیه نهال و بذر در کرج انجام شد. صفات آگرومورفولوژیکی...
Molecular mapping of cultivated oats was conducted to update the previous reference map constructed using a recombinant inbred (RI) population derived from Avena byzantina C. Koch cv. Kanota x Avena sativa L. cv. Ogle. In the current work, 607 new markers were scored, many on a larger set of RI lines (133 vs. 71) than previously reported. A robust, updated framework map was developed to resolve...
The present work indicates that phosphorylation of a 50 kDa soluble protein is involved in the gravitropic response in graviresponsive pulvini of oat (Avena sativa) stems. This 50 kDa protein shows a differential pattern of phosphorylation between lower and upper halves of pulvini both in vivo and in vitro. The differential phosphorylation of this protein is detected only when stem segments are...
The Subarctic comprises the higher mid-latitudinal regions with short, cool, moist summers and long, cold, dry winters. Indeed, the short, cool growing season is often thought of as a barrier to crop growth and diversity in these regions. Little is known, however, concerning the impact of the Subarctic climate on crop production. This study aimed to identify the climatic factors that are most i...
objective(s): nowadays, nanoparticles bio production, considering their performance in medicine and biological science, is increasing. green synthesis of metal nanoparticles using organisms has emerged as a nontoxic and ecofriendly method for synthesis of metal nanoparticles the objectives of this study were the production of silver nanoparticles using avena sativa l. extract and optimization o...
Although rapid auxin-induced growth of coleoptile sections can persist for at least 18 hours, acid-induced growth lasts for a much shorter period of time. Three theories have been proposed to explain this difference in persistence. To distinguish between these theories, the pH dependence for auxin-induced growth of oat (Avena sativa L.) coleoptiles has been determined early and late in the el...
Phytochrome was partially purified from etiolated seedlings of Avena sativa L. Several properties of the red-absorbing (P(R)) and far-red absorbing (P(FR)) forms of the pigment were compared. The 2 forms could not be shown to differ with respect to their sedimentation velocity in sucrose density gradients, elution volume from Sephadex G-200 columns, binding properties on calcium phosphate, or e...
Preservation and use of wild oat species germplasm are essential for further improvement of cultivated oats. We analyzed the transferability and utility of cultivated (white) oat Avena sativa (AACCDD genome) microsatellite markers for genetic studies of black oat A. strigosa (A(s)A(s) genome) genotypes. The DNA of each black oat genotype was extracted from young leaves and amplified by PCR usin...
Microorganisms which contaminate animal feeds pose a threat not only to animals but also indirectly to humans through their consumption of products of animal origin. The aim of the present study was to assess microbiological cleanness of selected resources and ready-made feed mixtures before and after thermal processing. The results indicated that the most bacteriologically contaminated resourc...
در این تحقیق از یک جداکننده وزنی برای جدا کردن یولاف از گندم استفاده شده است. دستگاه مذکور دارای پنج پارامتر قابل تنظیم سرعت هوا، دامنه نوسان، فرکانس نوسان، شیب طولی و شیب عرضی میز می باشد که تأثیر این پارامترها برای حصول به حداکثر جداسازی یولاف از گندم مورد بررسی قرار گرفت. تجزیه آماری در دو آزمایش فاکتوریل در طرح پایه بلوک های کامل تصادفی انجام شد. در آزمایش اول اثر سه پارامتر شیب طولی، شیب ع...
