in order to investigate the effect of phosphorus fertilizer and spraying fe chellat in micronutrients absorption rate, rate of proline and soluble carbohydrates in bread wheat and some of its ancestral species in dryland condition, a factorial experiment was conducted with three factors consist of: p fertilizer (in two levels), spraying fe chellat (in two levels) and different species of wheat ...

Plant zinc finger proteins (ZFPs) comprise a large protein family and they are mainly involved in abiotic stress tolerance. Although Arabidopsis RING/FYVE/PHD ZFP At5g62460 (AtRZFP) is found to bind to zinc, whether it is involved in abiotic stress tolerance is still unknown. In the present study, we characterized the roles of AtRZFP in response to abiotic stresses. The expression of AtRZFP was...

Revealing stress tolerance mechanisms in plants would contribute to the selection of crop varieties with a higher capacity for surviving unfavourable environments. In this regard, it is essential identify possible physiological features that might be beneficial increasing plant resistance stress. Two contrasting common wheat (Triticum aestivum L.) cultivars different drought were subjected 48 h...

Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...

Paper mulberry (Broussonetia papyrifera L. Vent) is well known for its bark fibers, which are used for making paper, cloth, rope, etc. It was found that, in addition to its well-documented role in the enhancement of plant salt tolerance, overexpression of the Na+/H+ antiporter (AtNHX5) gene in paper mulberry plants showed high drought tolerance. After exposure to water deficiency and salt stres...

Agriculture in semiarid regions commonly face problems because of salt and availability irrigation water. Considering this, studies on cultures resistant to water stresses involving sweet sorghum are required. Therefore, the aim was evaluate growth other mechanisms tolerance salinity deficit BRS 506 sorghum. The experimental design conducted Upanema-RN, Brazil, randomized blocks, where isolated...

Salinity is a major abiotic stress that poses great obstacles to wheat production, especially in arid regions. The application of exogenous substances can enhance plant salt tolerance and increase its productivity under salinity stress. This work aimed assess the mechanisms selenium (Se) at different concentrations (2, 4 8 ?M SeCl2) mitigate hazardous impacts toxicity physiological, biochemical...

The evaluation of biochemical markers is important for the understanding of the mechanisms of tolerance to salinity of Phaseolus beans. We have evaluated several growth parameters in young plants of three Phaseolus vulgaris cultivars subjected to four salinity levels (0, 50, 100, and 150 mM NaCl); one cultivar of P. coccineus, a closely related species reported as more salt tolerant than common...

to determine the effect of zn and mn enriched seed on quality of two winter safflower varieties under drought stress, an experiment was conducted at the agricultural faculty research field, tarbiat modarres university, during 2004-2005 cropping season. the design was a split factorial randomized complete block one of 3 replications. main plots were composed of 3 different levels of drought stre...
