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...

High temperature, high irradiance, low water vapour pressure, and lack of precipitation in most months characterize arid ecosystems. Under these conditions, trees such as pistachio suffer drought combined with salinity stress. In order to study the simultaneous effects of salinity and drought stresses on photosynthetic apparatus function in P. khinjuk, seedlings of the species were exposed to o...

drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of iran. detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. six wild populations of anthemis tinctoria, were assigned to four drought treatments, i.e. well-watered ...

Abstract In order to study the effect of water deficit stress on some physiological characteristics including leaf water osmotic and turgor potentials and osmolytes including sugars, proline and invertase activity of Persian melon (Cucumis melo Group. cantaloupensis cv. samsoury), an experiment was conducted in complete randomized design. Treatments including three irrigation levels (start of ...

This study was conducted to evaluate the effect of osmotic stress on physiological characters of wheat cultivars as a factorial experiment based on completely randomized design with three replications in 2012 at the Mohaghegh Ardabili University. Twenty wheat cultivars studied in three stress levels (control, -6 and -12 Bars). Analysis of variance showed that the stress had significant effect o...

Osmotic stress is the most important of the abiotic stresses that lead to limitation of growth and yield in rapeseed. This study was conducted to examine the effect of cycocel seed priming on osmotic stress tolerance in germination and early growth stages of rapeseed, as a factorial experiment based on completely randomized design at Agriculture College of Shiraz University in 2012. The treatme...

Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...

Dianthus barbatus is an important ornamental bedding plant in temperate regions with traditional medicinal applications. Water shortage and drought stress are major limitations for landscape development and plant medicine production. Callogenesis is the key step for modern plant breeding techniques and in vitro drought stress study defines the mechanisms of plant response to stress. Therefore t...

Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...
