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 ...

Neck shrivel is a fruit disorder of european plum ( Prunus domestica L.). We investigate whether an asymmetrical distribution osmolytes might explain the observations turgid stylar end and flaccid stem end, in selection 17 cultivars sourced from two sites. The osmotic potential (Ψ Π ) juices expressed or samples decreased (became more negative) during development. cell turgor P slightly increas...

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...

present study was conducted to investigate the effects of different osmotic potentials (0.0 mpa, -0.4 mpa, -0.8 mpa and -1.2mpa) induced by nacl and polyethylene glycol-6000(peg) as salinity and drought stress respectively on germination and early growth of two inbred lines of maize (mo17 and b73). the objective was to compare the germination ability between tow maize inbred lines in salt and d...

salinity affects plant growth by the osmotic stress of salt around the roots as well as by toxicity caused by excessive accumulation of salt in leaves. the study of photosynthetic traits as a rapid and non-destructive tool demonstrates the great potential for improving plant productivity and stress tolerance. a pot experiment was carried out to investigate short-term effects of osmotic stress (...

This study was conducted to understand how osmotic potentials in Lentinula edodes tissues are related to water contents and how they change while a mushroom matures. Water content and osmotic potential of L. edodes mushroom tissues from log cultivation and sawdust cultivation were measured and the relationships were analyzed. Osmotic potentials in the tissues were exponentially proportional to ...

An experiment was conducted to see the impact of osmotic stress as it is one of the main cause in various soil and water disorders in agricultural field crops, speciallythe seed germination and seedling growth. The osmotic stress was generated using PEG-6000 and the seed germination, seedling growth were evaluated including the status of pigments i.e. chlorophyll (a, b and total), total caroten...

zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...
