Morpho-physiological characteristics response of hull-less barley genotypes to water deficit stress
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 4
Abstract
In order to investigated the morpho-physiological characteristics response of hull-less barley (Hordeum vulgare L.) genotypes to water deficit stress an experiment was conducted in the split plot form based on completely randomized block design with three replications during growing seasons of 2013-2014. Treatments were water deficit stress in five levels contain irrigation each 7, 14, 21 days, cut of irrigation at heading stage and non irrigation (dry land condition). The second factor was 10 hulls-less barley genotypes. The analysis of variance showed that significant effect of water deficit stress on plant height and interaction effect between water deficit stress and genotype on spike length, number of fertile tiller, number of non fertile tiller and spikes number (P< 0.01), and leaf number, awn length, spikelet number (P< 0.05). The detailed results of the study showed that water deficit stress caused to decrease all of these characteristics and the various genotypes have different reactions in water deficit stress conditions. The correlations results appears that there is a positive correlation between spike number and plant height, the number of fertile tiller and peduncle length.
