This study deals with the best responses of a diverse collection grapevine genotypes to osmotic stress associated source-sink balance given by an estimator such as leaf area fruit ratio. ‘Centennial Seedless’, drought tolerant cultivar, was selected control. The cultivars, ‘Victoria’ and ‘Argessis’, were chosen repetition from previous research dealing pollen grain test, two years ago. Ten hybr...

Rice is one of the most important crops, providing staple food for about half population of the world. Drought stress affects plant growth and development seriously. This article reviewed the research progress of the physiological and molecular biology mechanism including osmotic adjustment, scavenging oxidative radicals, endogenous hormones, drought-resistance genes and epigenetic modification...
