Abstract Aims To explore whether grazing-induced legacy effects on plants could benefit adaptation to drought. Methods A water-controlled experiment was conducted in the greenhouse, which with Agropyron cristatum and Carex korshinskyi collected from free-grazing enclosed plots a typical grassland Inner Mongolia. Important Findings We found that A. C. plot were less affected by drought terms of ...
Silicon in forage reduces dry matter digestibility and may reduce grazing preference. Two studies were conducted with the following objectives: (1) to evaluate a method of determining grazing preference, and (2) to characterize the distribution and solubility of silicon in 31 accessions of C-3 grasses and relate these traits to grazing preference and estimated forage digestibility. Forage sampl...
The morphologically diverse genus Ceuthospora has traditionally been linked to Phacidium sexual morphs via association, though molecular or cultural data to confirm this relationship have been lacking. The aim of this study was thus to resolve the relationship of these two genera by generating nucleotide sequence data for three loci, ITS, LSU and RPB2. Based on these results, Ceuthospora is red...
هدف از این تحقیق ارزیابی تأثیر سطوح مختلف عناصر مس و سرب بر جوانه زنی و رشد بذور گونه trichophrumagropyron تحت شرایط آزمایشگاهی است. بدین منظور برای بررسی تأثیر این عوامل بر شاخصهای جوانهزنی و رشد بذور این گونه، دو آزمایش در قالب طرح کاملاً تصادفی با پنج تیمار (شاهد، 20، 50، 100 و 150 میلی گرم در لیتر) سولفات مس (cuso4) و نیترات سرب (pb(no3)2) در چهار تکرار انجام شد. با بررسی میزان بذور جوانه...
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive diseases of wheat (Triticum aestivum L.) worldwide. Agropyron cristatum (L.) Gaertn. (2n = 28, PPPP), one of the wild relatives of wheat, exhibits resistance to stripe rust. In this study, wheat-A. cristatum 6P disomic addition line 4844-12 also exhibited resistance to stripe rust. To identify the s...
