LOW WATER STRESS INDUCED CHANGES ON PHENOLOGICAL CHARACTERISTICS OF BARLEY (HORDEUM VULGARE L.) GENOTYPES.

Water stress regularly leads to attenuations not only crop growth and ultimately yield. Barley is the only crop that is showed more tolerant behavior among all the cereal. Existing investigation work carried out under irrigated and low water environment with three replications in the pot-house Department of Botany, Baba Mastnath University using a complete randomized design. Incorporation of drought alters the reproductive stage through shifting the flowering in addition to the time of maturity. Mean genotype of days to heading (92.5) in BH-902, days to anthesis (99.5) in AMBER and days to physiological maturity 131.5 in (DWRB-828) whereas, RD-57 had minimum days to heading (73.3), anthesis (81.7) and physiological maturity (111.7). Average relative water content was varied in genotypes from 50.2% to 78.6% and treatments from 70.0% to 53.2%. The present study showed that all genotypes show significant reduction under stress condition with significant interaction effect between genotypes and treatment. [ABSTRACT FROM AUTHOR]
