drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

in order to evaluate drought tolerance of cultivars and advanced grain sorghum lines, an experiment was conducted as split-plot on randomized complete blocks design with three replications at experimental field of seed and plant improvement institute, karaj in 2009. three levels of irrigation regimes including normal irrigation (ir0=60 mm), moderate stress (ir2=120 mm) and sever stress (ir3=180...

The genus Triticum includes bread (Triticum aestivum) and durum wheat (Triticum durum) and constitutes a major source for human food consumption. Drought is currently the leading threat on world's food supply, limiting crop yield, and is complicated since drought tolerance is a quantitative trait with a complex phenotype affected by the plant's developmental stage. Drought tolerance is crucial ...

Evaluation of Drought Tolerance in Camelina (Camelina Sativa) Doubled Haploid Lines Using Selection Index Ideal Genotype (SIIG)

Improving drought tolerance through drought preconditioning is an important way to understand drought tolerance mechanism in plants. Some limited researches have focused on the gene expression patterns in conjunction with the underlying enzymes promoting drought tolerance and post-drought recovery in white clover. The objective of this study was to identify whether preconditioning-induced droug...

Oxidative stress is commonly induced when plants are grown under drought stress conditions.To analyze how salicylic acid (SA) can partly alleviate drought-induced oxidative stress and negative impacts of drought on physiology and growth of Salvia nemorosa plants, we investigated the physiological responses of S. nemorosa to SA application under drought stress. The treatments were composed of Co...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...

Wheat improvement for drought tolerance requires reliable assessment of drought tolerance variability among segregating populations. One hundred and fifty-one F3 and F4 families of durum wheat derived from a cross between Oste-Gata (as drought tolerance) and Massara-1 (as susceptible) genotypes were evaluated both under moisture stress (E1) and non-stress (E2) field environments using a randomi...

The drought tolerance is a very important property of grapevine rootstocks. For that reason the breeding and selection of new rootstock varieties is focused also on the evaluation of their drought tolerance. In this experiment, altogether 20 new hybrids and 4 existing rootstock varieties were compared and evaluated. The experimental scheme involved 3 variants of water supply. Evaluated were the...

Drought is a major threat to agricultural production and drought tolerance is a prime target for molecular approaches to crop improvement. To achieve meaningful results, these approaches must be linked with suitable phenotyping protocols at all stages, such as the screening of germplasm collections, mutant libraries, mapping populations, transgenic lines and breeding materials and the design of...
