abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...

In this work, the effects of silicon (Si) supplementation were studied in pistachio (Pistacia veraL. cv Ahmadaghaii) plants exposed to high salinity stress. Plants were grown in pots undercontrol and salt (EC=15 dS m-1) conditions without or with Si treatment (0.35 g Na2SiO3 Kg-1soil) under field conditions. Salt stress reduced the plants’ growth significantly in both –Si and+Si plants; however...

The energetics and accumulation of solutes in Saccharomyces cerevisiae were investigated for cells grown aerobically in a chemostat under NaCl stress and glucose limitation. Changed energy requirements in relation to external salinity were examined by energy balance determinations performed by substrate and product analyses, with the latter including heat measurements by microcalorimetry. In bo...

abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...

Plants are exposed to various environmental stresses during their life cycle such as salt, drought and cold. Natural variation mediated plant growth adaptation has been employed as an effective approach in response to the diverse environmental cues such as salt stress. However, the molecular mechanism underlying this process is not well understood. In the present study, a collection of 82 Arabi...

The mechanism by which plants cope with salt stress remains poorly understood. The goal of this study is to systematically investigate the contribution and distribution of inorganic ions and organic compounds to the osmotic adjustment (OA) in the halophyte species Halostachys caspica. The results indicate that 100-200 mM NaCl is optimal for plant growth; the water content and degree of succulen...

Salinity is one of the most important abiotic stresses that limit crop growth and production. Salt stress influences plants in two ways: by affecting ion toxicity and increasing osmotic stress. Ion homeostasis, the excretion of Na+ and using antioxidant systems are the major strategies of salt tolerance in plants. Na+ and K+ transporters with enzymes that are involved in detoxification of react...

In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...
