Abstract Drought stress is an unavoidable challenge limiting plant production and quality. Stigmasterol a potential compound for protection improvement productivity under drought. Thus, the effects of using stigmasterol as exogenous treatment on improving growth sunflower grown drought were studied. A pot experiment was carried out at two summer seasons, foliar 0, 100, 200, 300 mg L −1 plants d...

Introduction: Streptomyces manage the osmotic stress by collecting compatible solutes or osmolytes. Ectoine, 1,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid, and 5-hydroxyectoine are among the most common osmolytes of this bacteria and have an active role in protecting the genetic material of this microorganism as well as providing resistance to environmental pressures. In this researc...

Choline and glycine betaine (GBT) are utilized as osmolytes to counteract osmotic stress, but also constitute important nutrient sources for many marine microbes. Bacterial catabolism of these substrates can then lead the production climate active trace gases such methylamine methane. Using radiotracers, we investigated prokaryotic choline/GBT uptake determined biotic abiotic factors driving pr...

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...
