Salinity reduces substrate water potential, thereby restricting water and nutrient uptake by plants; salinity may also cause ionic imbalance and toxicity. Because substrate salinity fluctuates through the growing season, a plant may be exposed to different salinity levels, at various stages of development, with potentially significant consequences on population dynamics. Here, we present the re...

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 of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. a greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (bamiand hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mm nacl) at the college of agriculture,shiraz university, shiraz, iran in 2008. plant dry weig...

In order to investigate of effect of salinity (NaCl) on soluble sugars and mineral ions concentrations in salt tolerant (IR651) and sensitive (IR29) rice (Oryza sativa L.) genotypes, a factorial based on a completely randomized design was carried out in greenhouse of physiology division of Agricultural Biotechnology Research Institute of Iran (ABRII) in 2006. Seedlings were grown in Youshida nu...

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

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...
