The main objective was to show a sequence and importance of the events that may be evoked in plants during slow or fast dehydration, from leaf growth inhibition, stomata opening and photosynthesis limitations, metabolic changes in tissues, to changes at the molecular level as many of them serve to plants to survive drought, to adapt to harmful environment, and to bring a yield. The work describes a set of methods used currently in physiological and eco-physiological research to study precisely the stress environment (fluctuations in soil and air water content, air temperature, irradiance, etc.) that influence considerably the plant physiological characteristics including net photosynthesis, stomata conductivity, characteristics of water regime, chlorophyll and fluorescence, synthesis of leaf metabolic components, etc. leading to modifications in growth-production process and in all the characteristics of ear. Various biological material, from well characterized barley genotypes of various proveniences with improved morphology and metabolism under water stress, mutants of Arabidopsis thaliana to wheat and bean was used
