Abstract. Of the various abiotic stresses, most important limitation of rice production in many countries is drought or water scarcity. The aim study to collection, hybrid and breeding varieties samples for tolerance prolonged soil air drought, select drought-resistant forms new varieties. Methods. objects research – 68 dry land were cultivated irrigated flooded areas (Proletarsk, Rostov region...

physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 mp) was studied on seed germination and plumule as well as radicule growth length in three species namely: agropyron elongatum, agropyron desertourm and secale montanum. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 100 seeds in four replications (petri dishes) were so...
