Economic and social pressures are spurring the study of alternate weed management strategies such as development competitive crop cultivars, capable being used under an integrated plan. The primary objective this research was to determine whether western Canadian spring wheat ( Triticum spp.) cultivars differ in their ability compete against model weeds those differences were expressed when cha...
Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...
به منظور شناسایی و تعیین غالبیت علف های هرز در 3 قسمت باغ ازگیل، انارستان و نارنجستان باغ ارم مطالعه ای در سال های 93- 1392 انجام گرفت. مشخصات گونه های مختلف علف هرز به تفکیک جنس و گونه مورد بررسی قرار گرفت. پس از انجام مطالعات میدانی، تراکم، فراوانی، یکنواختی و میانگین تراکم هر گونه و شاخص تنوع شانون- وینر ارزیابی شد. درهر قسمت طول و عرض جغرافیایی مکان های مورد اندازه گیری توسط دستگاه gps ثبت ...
Allelopathic activity of wheat (Triticum aestivum L.) has previously been associated with the production phenolic acids and flavonoids (PAF), benzoxazinones (BXZs) phenoxazinones (PXZs). The biosynthesis BXZs is closely regulated during cereal growth, accumulation highest in young tissues variation genotype environmental conditions. This review focused on BXZ metabolites their impact germinatio...
