this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

the deleterious effects of salinity on plant growth and development are associated with the imbalance ion in plant, decreased k+ and increased na+, and ultimately yield loss. in order to evaluate the effects of salinity, 41 bread wheat varieties (trticum aestivum l.) were planted in the randomized complete block design with three replications under two saline irrigation conditions, 0.631 and 11...

Salinity stress is a brutal environmental stress which decreases the yield production of plants. Questions rise on which of the ionic stress or lack of water has deleterious effects on plants forage dry yield. Also, questions remain on whether the K+ reduction or Na+ accumulation is more important in forage dry yield reduction under salinity stress. The present experiment was conducted to answe...

selection and use of tolerant grapevine as rootstock or own-rooted vines and finding indexes for screening of resistant genotypes have especial importance. to identify the salt tolerant grapevine genotypes, effects of nacl concentrations (0, 50, 100 and 150 mm) on root length, root and shoot dry weight, prolin, total soluble solid, rwc, level of salt injury, leaf concentration of k, na, cl and ...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...

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...
