To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...

Dianthus barbatus is an important ornamental bedding plant in temperate regions with traditional medicinal applications. Water shortage and drought stress are major limitations for landscape development and plant medicine production. Callogenesis is the key step for modern plant breeding techniques and in vitro drought stress study defines the mechanisms of plant response to stress. Therefore t...

چکیده روغن اسانسی اندام های هوایی دو گونه گیاهی ایران از خانواده نعنائیان (nepeta persica، nepeta asterotricha) به دو روش تقطیر با آب و head space به دست آمد و ترکیبات موجود در آن ها به وسیله کروماتوگرافی گازی همراه با طیف سنجی جرمی جداسازی و شناسایی گردید. در روغن اسانسی حاصل از اندام هوایی n. persica، 18 ترکیب از 22/92% کل اسانس شناسایی شد و محصولات عمده (5/16%) 4a?, 7?, 7a? nepetalactone، ...

This research was performed in 2011 at University of Mohaghegh Ardabili, Iran, to evaluate osmotic-stress tolerance, at seedling stage, of rapeseed (Brassica napus L.), as a split plot experiment based on randomized complete blocks design with four replications. Levels of osmotic stress were considered as main factor and twelve rapeseed cultivars were sub-factor, that were evaluated under aquac...
