Correlation and path analysis of physiological characters in greengram under moisture stress in vegetative stage

摘要

Correlation and path coefficients were worked out for physiological characters in greengram under moisture stress in vegetative stage. Leaf area, dry matter, relative water content, soluble protein, nitrate reductase activity, catalase activity and peroxidase activity were positively and significantly correlated with seed yield. Proline content showed a negatively significant association with yield. The nature and form of association with each other manifest by relative water content, soluble protein, nitrate reductase activity, catalase activity and peroxidase activity with particular reference to the direction and magnitude and the direct and indirect effects where similar and resembled each other. These five characters influenced the observed associations with the yield through their direct and indirect effects and hence found important in the improvement of greengram under moisture stress situations.
