| Abstract | Experiment was conducted with 7 mungbean varieties to determine the effect of cadmium toxicity on the growth, yield and yield components. The decrease in seed yield per plant under cadmium toxicity was more pronounced with a reduced number of seeds per pod and number of seeds per plant. Consequently cadmium toxicity was more effective at seedling, vegetative and seed filling stages rather than seed development stage in all the 7 varieties. NM-98 was less affected which showed its adaptability for Cadmium stress conditions. Mungbean is an important legume species and thinning. provides an important source of human diet. A survey of The pots were randomly placed in a green house. literature reveals that genera Vigna and Phaseolus have The physico-chemical characteristics of soil were; organic not been extensively investigated with respect to Cd matter 1.4%; cation exchange capacity 11.5 meq l ; pH toxicity effects. Available reports depict that mungbean 7.6; EC 0.7 dS m-1; sodium absorption ratio 0.06 meq l ; (used to be denoted by the genera Vigna and Phaseolus) Na+ 2.39 meq l ; Cl- 7.85 meq l -1; SO4 2 - 1.49 meq l shows sensitivity to Cd toxicity and the effects are and Ca + Mg 14.7 meq l . The average temperature discernible at molecular and physiological levels. during the experiment was between 33°C ± 4 to 40°C ± 3, Although genotypic differences exist (1), the Cd relative humidity between 27% ± 4 to 35% ± 8 and rainfall application decreases the shoot and root growth (2,3), leaf ranged from 64mm to 86 mm. Cadmium chloride solution area (4) and ultimately the dry matter yield of mungbean with 0, 3,6,9 and 12 mg/Kg were added to soil at different (5,6). It perturbs the stomatal regulation, abscisic acid growth stages i.e., seedling, vegetative and maturity content, water status of leaves (7) and nitrogen fixing stages. Tap water was used for irrigation throughout the ability and enzymes of ureid biosynthesis in the nodules growth period as and when required. The EC of the tap (8). Geuns et al. (9) suggests that based on changes water was also measured by EC meter, which ranged from occurring in growth and physiological attributes, 0.3 to 0.7 dS m-1 during the experiment. The data for mungbean can be regarded as bioindicator of Cd toxicity. growth yield and yield components were recorded at |
