Salinity is one of the main obstacles to the successful production of agricultural products. Hormonal compounds such as salicylic acid (SA) as plant growth regulators can have different physiological and biochemical effects in plants under salt stress. In present research, the effects of different concentrations of sodium chloride (2, 6 and 10 dS/m) and foliar application of SA (0, 0.25 and ...

Abiotic stresses including salinity are the major limiting factors of growth and crop production worldwide. Microbial endophytes as the most important soil microorganisms, by modifying plants at genetical, physiological and ecological levels increase their yield per area unit and provide the possibility of crop production in saline and arid soils or climates with biotic and abiotic stresses. Th...

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...
