in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), ...

Stress can be defined as a state of increased psychological, physiological and behaviourial preparedness. A stress reaction is a normal reaction that is considered necessary rather than harmful. Physical activity is generally deemed a stress factor that activates our physiological stress systems in the same way as exposure to psychological stress. The following chapter describes acute stress re...

Reactions in the Earth's crust occur through a dissolution-precipitation process presence of fluid. Dissolution releases aqueous species which are transported to locus precipitation. This replacement generates creep deformation (i.e., creep) due volume change during reaction and stress-controlled mass re-distribution rock. Reaction under stress also modifies rock microstructure pressure record ...

the sucrose non-fermenting 1-related protein kinase 2 (snrk2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. the three snrk2 members including srk2d, srk2i and srk2e are known to phosphorylate major abscisic acid (aba) responsive transcription factors, abf2 and abf4, involved in an aba-dependent stress signal...

high temperature, high radiance, low vapor pressure, and lack of precipitation in most months characterize arid ecosystems. under these conditions, tree crops such as pistachio suffer from drought combined with salinity stress. in order to investigation effects of combined salinity and drought stress on function of photosynthetic apparatus, mutica pistachio (pistacia mutica) seedlings were subj...
