using plant probiotic bacteria, which can induce systemic tolerance in plants, is one of the most important strategy to reduce the damage of drought stress in plants. in this study the effect of four fluorescent strains (t17-4, vupf5, 428, cha0) was investigated on resistance of two pistachio cultivars (badami-rize-zarand and sarakhs) against the drought stress. a completely randomized design w...

introduction major cultivated cotton regions of iran are located in dry and semiarid climates, therefore water deficiency or drought stress is inseparable part of cotton production systems in these regions. so identification and introduction of drought tolerant cotton genotypes is crucial. showed that water stress decreased plant growth rate, leaf area and finally photosynthesis in cotton. in a...

in order to investigate the effect of silicon application on some physiological characteristics and growth of wheat (triticum aestivum l.) under late drought stress condition, an experiment was conducted at the agriculture and natural resources university of ramin, khuzestan during year 2012. the experiment was conducted in the open environment as factorial randomized complete block design with...

to study general combining ability (gca) and estimation of heterosis in sunflower inbred lines for seed yield and other three agronomic traits, 68 inbred lines crossed with open pollination variety lakumka. in next year inbred lines along with topcrosses were planted in rcbd with 2 replications under two moisture conditions in sararood agricultural research station. analysis of variance in both...

water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...

rainfall deficiency and the development of salinity in iran are the most important factors for using new salt and drought-resistant plants instead of conventional crops. kochia species have recently attracted the attention of researchers as a forage and fodder crop in marginal lands worldwide due to its drought and salt tolerant characteristics. this field experiment was performed at the salini...
