Abstract

Effect of Chlor-alkali Effluent on Root and Shoot Length of Seedlings of Some Plants

Author(s): Dashmeet Kaur Arora and Dr. S. P. Singh

Impact of Chlor-alkali effluent (CAE) was analysed on Barbati (Vigna sinensis), Methie (Trigonella foinumgraecum), Tomato (Lycopersicum esculentum),Soyabean (Glycine max), Mustard (Brassica nigra) and Onion (Allium cepa). Parameters selected were root length and shoot length of seedlings. Effect of chlor-alkali effluent was analyzed at different dilutions viz. 10%, 20%, 40%, 60%, 80%, 100% and control. At 10% effluent concentration, mean length of seedlings of Vigna sinensis, Brassica nigra, Lycopersicum esculentum, Glycine max and Trigonella foinumgraecum was increased whereas mean length of seedling of Allium cepa decreased when compared with con-trol condition. At 20% effluent concentration, mean length of Trigonella foinumgraecum and Brassica nigra were promotory when compared with their controlled condition. In case of Vigna sinensis, Allium cepa and Glycine max, mean length of seedlings was inhibited but there was no effect on mean length of Lycopersicum esculentum in re-spect with controlled condition seedlings. At 20% to 100% effluent concentration, the mean length of seedlings of all species was inhibitory when compared with mean length of seedlings of control conditions.<
