Physiological basis of genetic variability in drought response and its association with yieldand related indices is not clear in Brassica. In this study 36 accessions belonged to sevenspecies of Brassica were evaluated under normal, moderate and severe stress environments.Physiological traits along with seed yield, seed yield components, oil content and two selectionindices (stress tolerance in...

The ch4 mutant of sweetclover (Melilotus alba) has previously been demonstrated to be partially deficient in chlorophyll and to have a higher ratio of chlorophyll a to b than normal plants. We were able to substantiate these findings when plants were grown at 23 degrees C and lower (permissive temperatures). However, when grown at 26 degrees C (nonpermissive temperature) the plants produced sma...

in this study, effect of exogenous putrescine on maintaining postharvest quality and antioxidant compounds of two broccoli cultivars, ‘general’ and ‘liberty’ during cool storage were investigated. broccoli branchlets were treated with 0.5, 1 and 1.5 mm putrescine. distilled water was used as control. treated florets were put into polyethylene bag and transferred to storage with 0°c and 90% rh. ...

This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...

Stress management is considered as an important factor in nowadays landscape. Therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (Lolium...
