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...

Borage is an important medicinal plant which must be cultivated commercially in order to meet the ever-increasing demand for pharmaceutical industry. This study was done under hydroponics condition. Seeds of Borage were obtained from Neka Research Center (North of Iran). After applying Benomyl fungicide, the seeds were rinsed with distilled water and planted in vermiculite. After germination an...

A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...

The mangrove habitat exhibits many unique physical features, one of the most important of which is a salinity gradient. Photosynthetic rates, as measured by leaf stomatal conductance and leaf chlorophyll fluorescence induction, were tested as indicators of salinity stress in seedlings of the red mangrove, Rhizophora mangle, grown under five different salinity levels: 0, 15, 30, 45, and 60 parts...

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...

Soil salinity is one of the most severe factors limiting nodulation, yield and physiological response in soybean. The possible role of plant growth promoting rhizobacteria (PGPR) in restricting mineral nutrients and thus alleviating soil salinity stress during plant growth has not yet been established. In this study, the beneficial effects of inoculation with salt-stressed PGPR strains were inv...

Salinity is one of the most important constrain affecting crop growth and productivity. Hence studying salinity at morphological and biochemical point of view has become the basis for understanding salinity and plant interactions. Under stress, plants survive by enhancing the osmolyte accumulation by complex metabolic activities. Present investigation deals with the effect of salinity on growth...

salinity stress results to decreasing leaf area index (lai) and light absorption in plant leading in yield decrease. in order to study effect of salinity and iron sulphate on lai, absorbed light percentage and yield of sunflower (euroflor cultivar), an experiment was carried out as split plot based on complete randomized block design with four replications in the research field of university of...

soil salinity poses considerable and increasing problems for agriculture, and is receiving much attention from plant breeders. the identification of genes whose expression enables plants to adapt to and/or tolerate salt stress is essential for breeding programs, but little is known about the genetic mechanisms of traits in saline conditions. the data obtained from 75 families produced by crossi...

Salinity stress as a major agricultural limiting factor may influence the chemical composition and bioactivity of Rosmarinus officinallis L. essential oils and leaf extracts. The application of salicylic acid (SA) hormone may alleviate salinity stress by modifying the chemical composition, gene expression and bioactivity of plant secondary metabolites. In this study, SA was applied to enhance s...
