In recent years, the involvement of nitric oxide (NO) in numerous physiological processes, particularly the mitigation of stress-induced negative effects on plants, has been clarified. Under salinity conditions, plants are subjected to a secondary oxidative stress. The present work was designed to examine the exogenous application of nitric oxide (NO), in the form of its donor sodium nitr...
reduction of deleterious effects of salt stress using some plant bioregulators has been reported in different plant species. salicylic acid (sa) has been considered as a signaling molecule and it is known to ameliorate the oxidative damage caused by environmental stresses such as salt stress. the present study was conducted to investigate the effects of sa on different growth characteristics, p...
Canola (Brassica napus L.) is one of the most important world's oilseed crops. The salin soils and salinity is the most important environmental stress factor that affects production of rapeseed. In order to study salinity resistance in canola cultivars at seedling stage based on morphophisiyological traits and assessing relation of these traits with ISSR markers, 15 canola cultivars in two sali...
An experiment was conducted to determine the responses of 27 Iranian local and improved rice genotypes to two salinity levels (0 and 100 Mm NaCl) at Soilless Culture Research Center of Isfahan University of Technology. The treatments were arranged as factorial in a completely randomized design with three replications. The results showed that there was considerable variation in agro-morphologica...
Acacia ampliceps (salt wattle), a leguminous shrub, has been introduced in salt-affected areas in the northeast of Thailand for the remediation of saline soils. However, the defense mechanisms underlying salt tolerance A. ampliceps are unknown. We investigated various physio-biochemical and morphological attributes of A. ampliceps in response to varying levels of salt treatment (200-600 mM NaCl...
Soil salinity is an increasingly serious problem worldwide that reduces agricultural output potential. Selected beneficial soil bacteria can promote plant growth and augment tolerance to biotic and abiotic stresses. Bacillus subtilis strain GB03 has been shown to confer growth promotion and abiotic stress tolerance in the model plant Arabidopsis thaliana. Here we examined the effect of this ben...
introduction abiotic stresses cause 71% reduction in crop yield around the world, from which 20% is related to salinity stress. the importance of sugarcane increases every day due to greater demand for sugar. since sugarcane has mainly grown in arid and semi-arid regions, salinity is one of the main problems for this crop due to higher evaporation in these areas. salicylic acid (sa) is classifi...
Salt stress is one the major environmental stresses limiting quantitative and qualitative aspects of plant growth. One of the methods to overcoming the adverse effects of salinity is application of growth regulators. Salicylic acid is a plant growth regulator its positive effects in alleviating the adverse effects of stresses on plants have been reported. In order to study the effect of salicyl...
High carbon dioxide (CO2) concentration in atmosphere has direct effects on plants activities. In order to investigate the effect of increased CO2 concentration from 380 to 700 and 1050 mg/L on some chemical and physiological characteristics of Amaranthus tricolor under three salinity treatments (0, 150, and 300 mM NaCl), an experiment was conducted in Research Greenhouse of Ferdowsi University...
introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...
