salicylic acid (sa) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. it has been recognized as an endogenous regulatory signal in plants. in order to study the effect of different concentrations of sa on germination, growth and some physiological parameters in chickpea (cicer arietinum l.) two genotypes (mcc414, mcc361) under drought stress conditions, ...

abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...

objective: to evaluate the effect of chemical stimuli on germination and seedling growth of caper (capparis spinosa) under drought stress. methods: factorial experiment in a completely randomized design with four replicates per treatment were performed. first factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/l), gibberellic acid levels (500, 250 and 125 ppm), a...

Adaptation of plants under drought and salinity stress depends directly on the type of soil texture. Therefore, in this research, the morpho-physiological variations of Stachys multicaulis, an Iranian wild endemic plant species, were investigated in different soil textures under drought and salinity stress. For this purpose, plants were cultivated in three different light, medium and h...

introduction drought stress as the most important abiotic stress plays an important role in yield reduction of crops worldwide. considering the extends and problems caused by the moisture stress, agronomic and breeding strategies in reducing yield loss are essential. in this regard, the identification and selection of effective characteristics of wheat under drought stress in increasing yield, ...

Drought stress is one of major factors resulting in maize yield loss. The roles of abscisic acid (ABA) have been widely studied in crops in response to drought stress. However, more attention is needed to identify key ABA-related proteins and also gain deeper molecular insights about drought stress in maize. Based on this need, the physiology and proteomics of the ABA-deficient maize mutant vp5...
