to determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. in experiments 1 and 2, the effects of salinity on growth indices were studid. experiments were donein the form of split plot based on rcbd. in each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (eciws). in experiment 1, ...
The present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vYaghouti. The experiment was done at Agricultural and Natural Resources Research Center, Ilam, Iran at 2014. The experiment was a completely block design (CRD) with four replications. Saline factor was NaCl salinity in seven levels (Zero, 50, 100, 150, 200 and 250 mM). Grap...
Water deficiency stress as the most important abiotic stress plays an important role in the yield suppression of plants worldwide. Considering physiological indices to improve drought resistance is of paramount importance. The objective of present study was to evaluate the effects of different irrigation intervals (irrigation after 5, 7, 9 and 11 days) and rates of superabsorbent polymer (Nil, ...
Black cumin (Nigella sativa) is an annual flowering plant in the family Ranunculaceae that beside medicinal value was used as food and cosmetics products. Salicylic acid is a growth regulator with phenolic nature has main role in regulation of many physiological processes and resistance to environmental stress. In order to study effect of salt stress and salicylic acid on some growth parameters...
In order to investigate the effect of different levels of water stress on Satureja hortensis, a completely randomized design (CRD) with four replications was carried out in the greenhouse of Yazd University in 2014. The water stress treatments including 100, 75, 50 and 25 Percent of field capacity (FC) were applied. The results showed that water deficit stress significantly (p<0.01) decreased p...
Drought is one of the environmental stresses, which have detrimental effects on most of plant growth stages, structure of organs and their activities. This experiment was conducted in 2014 to study the effects of drought stress on vegetative and biochemical changes of three six ornamental species include Ipomoea carnea, Delonix regia, Lantana camara, bougainvillea glabra, dodonaea viscose, cler...

introduction drought stress is the most important growth limiting factor for crop production. sugar accumulation under drought stress strengthens and stabilizes cell membranes and maintains the water absorption and turgid property. under stress conditions, proline will also maintain the turgor pressure and decreased the damages caused to plant membrane. although proline concentrations may have ...
zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...
response of tea plants to b deficiency was studied in hydroponic medium under environmentally controlled conditions. plants height, number of leaves and dry matter production of shoot and root were significantly decreased by b deficiency. concentration of chlorophyll, carotenoids, anthocyanins and flavonoids was not affected by b deficiency in the young leaf, while a significant reduction of ch...
