TAILIEUCHUNG - Different degree of drought stress affects morpho-reproductive growth in wheat (Triticum aestivum L)

Experiment was carried out to study the impact of induced water stress at different crop developmental stages for morpho-reproductive growth characters in two wheat cultivars at experimental area of Division of Bio chemistry and Physiology SKUAST J, in 2013. The experiment was laid out with two wheat varieties ., PBW-343 and RSP-81 with 04 water stress levels. T1 (without withholding of water), T2 (10 days with-holding of water [WOW]), T3 (15 days WOW) and T4 (20 days WOW) were applied. Increased water stress significantly reduced the plant height, number of leaves per plant, leaf area per plant, fresh and dry weight of leaves, stem and roots per plant, number of tillers per plant, number of fertile tillers per plant and number of unfertile tillers per plant in both wheat varieties. About and reduction in plant height was noticed at 20 days withholding of water in variety PBW-343 and RSP-81, respectively as compared to control. Number of leaves per plant was reduced by 50 and at highest drought condition in variety PBW-343 and RSP-81 respectively in comparison to control. Likewise, leaf area also reduced by and in variety PBW-343 and RSP-81, respectively. Fresh weight of leaf decreased by 75 and % in variety PBW-343 and RSP-81, respectively in comparison to control at 20 days WOW. Same trend was noticed in fresh weight of stem and roots per plants. | Different degree of drought stress affects morpho-reproductive growth in wheat (Triticum aestivum L)
