Wilczek] genotypes to waterlogging at vegetative stage [Elektronische Daten] [Pramod Kumar, Madan Pal, Rohit Joshi, R. Sairam] A study was conducted to examine the physiological response of contrasting mung bean (Vigna radiata) genotypes viz., T 44 & MH-96-1 (tolerant) and Pusa Baisakhi & MH-1K-24 (sensitive) under waterlogging conditions. Plants were waterlogged at vegetative stage (30days after sowing) for 3, 6 and 9days. Waterlogging resulted in decreased leaf area, crop growth rate, root growth and nodules number, membrane stability index, photosynthesis rate, chlorophyll and carotenoid contents, flowering rate, pod setting, yield and altered dry matter partitioning. Sensitive genotypes showed large reductions in aforementioned physiological traits and slow recovery in photosynthesis rate. On the other hand, tolerant genotypes maintained higher photosynthetic rate, chlorophylls and carotenoids, growth rate, membrane stability and fast photosynthetic recovery under waterlogging. After 9days of exposure to waterlogging, photosynthetic rate and yield losses in most sensitive genotype (MH-1K-24) were 83 and 85%, respectively. On an average, photosynthetic loss at 3, 6 and 9days of waterlogging was 43, 51, and 63%, respectively, while grain yield loss was 20, 34 and 52% respectively. Prof. H.S.
