Lycium depressum L. is the only native tree-like life-form species inhabited in saline and alkaline regions of Turkmen Sahra located at Golestan province in Northern Iran. During past years, efforts have been made to increase vegetation cover of the area by cultivation of L. depressum L. to reduce water and wind erosions and dust storm challenges; however, the cultivation of t...

Salinity stress acts as a significant deterrent in the course of optimal plant growth and productivity, mung bean, being relay crop cereal cropping system, is severely affected by salinity. Silicon (Si), on other hand, has exhibited promising outcomes with regards to alleviating salinity stress. In order understand critical mechanisms underlying bean (Vigna radiata L.) tolerance towards salt st...

Morpho-physiological response of 7 rice (Oryza sativa L.) varieties viz., Moroberekan, Co39, Azucena, Bala, IR64, Kalinga-III and Nipponbare was assessed under control and 100 mol m NaCl + 5 mol m CaCl2 stress in a flood bench system in greenhouse. Physiological and growth parameters were recorded after 21 or 42 days of salt stress. The statistical analysis revealed significant differences amon...

The influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (Beta vulgaris L. cv. IC) and a salt sensitive glycophyte (Nicotiana rustica L. cv. Basmas). Low-level salinity (25 mM NaCl) and high salinity (150 and 50 mM NaCl for sugar beet and tobacco, respectively) were supplied in hydroponics. Under low salinity shoot dry ...

Drought, salinity and extreme temperatures are the most common abiotic stresses, adversely affecting plant growth and productivity. Exposure of plants to stress activates stress signalling pathways that induce biochemical and physiological changes essential for stress acclimation. Stress tolerance is governed by multiple traits, and importance of a few traits in imparting tolerance has been dem...

this study was carried out within 7 months in dikjeh area, golestan province, iran. during that time the relationship between water salinity and ec with hematocrite, blood serum ionic parameters, growth, survival and stress indices in common carp (cyprinus carpio) were investigated. hematocrite as stress index was measured by hemocitometry standard method using microhematocrite reader. fish bio...

Salt stress is a serious problem facing plant growth and development. Selenium (Se) could improve plant growth and reduced stress. Hence, the aim of this study was to determine whether the Se application could alleviate salinity stress negative effects on Melissa officinalis L. Different salinity levels in this research were control (0), 50, 100 and 200 mM. Simultaneously, sodium selenate (Se) ...

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...

Salinity in soil and irrigation water is one of the major factors that limit crop productivity. The effects of salinity on growth, lipid peroxidation, the antioxidant defence system and changes in artemisinin content were studied in Artemisia annua L. Salinity treatments were established by adding 0, 50, 100, 150 and 200 mM of sodium chloride (NaCl) to the soil. Salt stress negatively affected ...
