The effect of salt stress on ion accumulation, photosynthesis and compatible solute contents in four grapevine (Vitis vinifera) genotypes
Salinity tolerance of four grape genotypes [GharaUzum, Hosseini, AghUzum and Keshmeshi] was studied under various salinity levels (25, 50 and 100 mM NaCl). As a result, growth indices were significantly (P<0.05) reduced by salinity, whereas Cl- and Na+ contents in the plant parts were increased. Cl- accumulation exceeded than that of Na+ in all treatments. Among the genotypes studied, GharaUzum...
متن کاملRelationship Between Ion Accumulation and Plant Biomass of Alfalfa Under Salt Stress
Abstract Salinity is one of the major abiotic challenges influencing plant productivity worldwide. To examine the response of two alfalfa cultivars (Bami and Hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mM L-1 NaCl), a glasshouse experiment was conducted at the College of Agriculture, Shiraz University, Shiraz, Iran in 2008. The results showed that in Bami (which appeared...

متن کاملEvaluation of four chamomile species under late season drought stress
To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...
متن کاملGlucosylglycerol, a compatible solute, sustains cell division under salt stress.
The cyanobacterium Synechocystis sp. PCC 6803 accumulates the compatible solute glucosylglycerol (GG) and sucrose under salt stress. Although the molecular mechanisms for GG synthesis including regulation of the GG-phosphate synthase (ggpS) gene, which encodes GgpS, has been intensively investigated, the role of GG in protection against salt stress remains poorly understood. In our study of the...
