Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...

this study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. genotypes were sown under normal irrigation and moisture stress conditions. in stress ...

background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought  stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...

Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...

Objective: In order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of Kermanshah Sararood Dry Land Agricultural Research Institute, located on the western part of Iran. Methods: The experimental design was a randomized lattice design with tow ...
