Multivariate analysis of the salinity-induced alterations in morphology, physiology, nodulation, and yield in two contrasting mungbean varieties

Changes were estimated in the morphology, physiology, photosynthesis, nodulation, and yield two mungbean varieties ‘PKV AKM 12-28’ ‘VBN (Gg)3’ under salt stress (0, 75, 100, 125 mM NaCl) for 15, 30, 45 days. Multivariate modelling was used to analyse results explore complex data visualize time concentration-dependent modulations. Principal component analysis showed modulations morpho-physiological attributes such as shoot length, root number of secondary branches, fresh weight, dry weight leaf area; photosynthetic chlorophyll ‘a’, ‘b’, total chlorophyll, carotene anthocyanine content; nodulation nodules per plant, size nodule, pods pod, seed characteristics seeds pod 1000 are key traits affected by can be indicators. Discriminant identified area, length chlorophyll-a content, mean nodule discriminating variables at different concentrations. Besides, it identified anthocyanin content attribute various durations stress. discriminant ‘PKV-AKM salt-tolerant salt-susceptible varieties. Multiple correlation significant correlations among morphological, physiological, photosynthetic, parameters.
