چکیده تنش کمبود آب در گیاهان، یکی از مسائل عمده در کاهش عملکرد در کشاورزی به خصوص در مناطق گرمسیری، نیمه خشک وخشک جهان می باشد. آزمایش فاکتوریل براساس طرح کاملاً تصادفی با چهار سطح آبیاری شامل: سطح آبیاری شاهد(بدون افزودن مکمل و بدون کاهش آبیاری)، سطح آبیاری صفر در صد (افزودن مکمل و عدم کاهش آبیاری)، سطح آبیاری 20 درصد (افزودن مکمل و کاهش یک مرحله آبیاری) و سطح آبیاری 40 درصد (افزودن مکمل و کا...
annually, 200 ha of agh ghala rangelands in golestan, iran are under alkaligrass puccinella distans''s cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. the current study aims to reduce such costs through the examination of apt sites to grow p. distans in northern rangelands of agh ghala golestan, iran. because of the...
The present work was undertaken to evaluate the polyphenolic content, antioxidant and antiviral properties of two wild medicinal plants; Achillea fragrantissima and Nitraria retusa. The crude extracts of both plants were prepared using methanol and ethyl acetate solvents. Generally, total phenolic content ranged from 0.31 to 15.05 mg gallic acid equivalents /g dw, where total flavonoid content ...
Six wild populations of Nitraria retusa growing in Tunisia (Mehdia, Mtorech, Kataena, Matmata, Bechima, and Tataouine) were evaluated for their mineral contents, phytochemical composition, phenols content and antioxidants activity.
