in this study, we assessed the relative contribution of organic and inorganic solutes to osmotic adjustment (oa) in three almond rootstocks subjected to four levels of soil salinity. the results showed that leaf water and osmotic potentials were affected by salinity in gf677 and bitter almond, but less so in gn15, suggesting a higher selectivity for k+ and ca2+ against na+ in this latter rootst...
abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...
in order to study the reaction of barley genotypes to drought, an experiment was conducted in a factorialdesign based on crd for two wild ecotypes and four crop genotypes of barley in greenhouse. in thisstudy, the barley genotypes and wild ecotypes as the first factor and irrigation treatment with three levelsinclude 70 percent of water holding capacity of soil, 30 and 10 percent as the second ...
For many organisms there is a correlation between increases of metabolites and osmotic stress tolerance, but the mechanisms that cause this protection are not clear. To understand the role of polyols, genes for bacterial mannitol-1-P dehydrogenase and apple sorbitol-6-P dehydrogenase were introduced into a Saccharomyces cerevisiae mutant deficient in glycerol synthesis. Sorbitol and mannitol pr...
