جنس lolium یکی از مهمترین گرس های علوفه ای مناطق معتدله است که از نواحی مدیترانه ای منشأ گرفته است. با توجه به گسترش طبیعی این جنس در ایران، شناسایی نمونه های موجود، بررسی تنوع ژنتیکی آنها و استفاده از این تنوع در به نژادی گیاهان از اهمیت ویژه ای برخوردار است. بنابراین، در تحقیق حاضر کلکسیون lolium بانک ژن گیاهی ملی ایران شامل 111 جمعیت در مزرعه کشت و شناسایی شده و همچنین تنوع ژنتیکی آنها بر اس...
Arbuscular mycorrhizal fungi (AMF), a special microorganism can connect soil and a plant directly, plays an important role in environmental remediation [1]. When the plant is in the heavy metal adversity, mycorrhizal association can enhance the resistance to the metals of plants [2]. Chen et al. [3], reported Cu uptake by four kind of mycorrhizal plants including two native plant species, Coreo...
In this study, the effect of two allelochemicals, benzoxazolin-2(3H)-one (BOA) and cinnamic acid (CA), on different physiological and morphological characteristics of 1-month-old C(3) plant species (Dactylis glomerata, Lolium perenne, and Rumex acetosa) was analysed. BOA inhibited the shoot length of D. glomerata, L. perenne, and R. acetosa by 49%, 19%, and 19% of the control. The root length o...
Two experiments were performed with post-valve T-cannulated growing pigs, using five animals in each experiment in a change-over design to evaluate the effect of inclusion of four different dried forage meals on ileal crude protein (CP) and amino acid (AA) digestibilities. The control diets (C1 and C2) were barley-based and the experimental diets were formulated by replacing the barley with 100...
Management of agroecosystems with herbicides imposes strong selection pressures on weedy plants leading to the evolution of resistance against those herbicides. Resistance to glyphosate in populations of Lolium perenne L. ssp. multiflorum is increasingly common in California, USA, causing economic losses and the loss of effective management tools. To gain insights into the recent evolution of g...
