Abstract:

The present study was aimed at evaluating chloride and sulphate dominated salinity stress tolerance status of the Senna (Cassia angustifolia Vahl.) at vegetative, flowering and pod maturity stage, a pot factorial experiment based on randomized complete design with three replicates was conducted in screen house. Four varying EC levels viz. control (without salt), 4, 8 and 12 dSm-1 of each salinity types along with nutrients supplemented in sand filled polythene bags. The present study revealed that various growth attributes such as plant height, number of leaves per plant, leaf dry weight per plant and stem and branches dry weight per plant progressively reduced with the successive increase of EC levels in the growing medium at different stages. Although the two salinity types did not differ significantly in their response on plant height, number of leaves per plant and leaf dry weight per plant at the vegetative stage but their differential effect became more pronounced at the flowering and pod maturity stages. Significant differential response of the two salinity types on stem and branches dry weight per plant was recorded only at the pod maturity stage. Significant decline in chlorophyll ‘a’, chlorophyll ‘b’ and total chlorophyll content of Senna with concomitant increase of EC level at the vegetative stage. More conspicuous reduction in growth attributes and contents of above pigments was observed under sulphate dominated salinity as compared to chloride dominated salinity. Senna appeared to be highly salt tolerant medicinal herb as its plant survived and reproduced at highest salinity level (12 dSm-1).
