Abstract/Description: | Bael (Aegle marmelos) cultivars NB-5, NB-9, CB-1 and CB-2 were grown in normal (ECe 1.3 dS m-1), moderate (6.5 dS m-1) and high (10.7 dS m-1) saline soils. The cultivars, evaluated for changes in appearance, leaf chlorophyll pigments and ionic relations, exhibited salt stress symptoms as yellowing, scorching and chlorosis of the leaves. Majority of the affected leaves subsequently abscised from the plants. Salinity significantly increased membrane injury and caused reduction in relative water content in all the cultivars. Accumulation of total soluble sugars in salt treated plants showed genotypic differences with NB-5 plants recording their maximum accumulation. Leaf chlorophyll (a, b and total) values showed a consistent decrease with increase in salinity except for NB-5 plants which exhibited slightly higher chlorophyll contents at moderate salinity. All the cultivars except NB-5 exhibited significantly higher leaf Na+ concentrations with increasing salinity while the plants of cultivar NB- 5 maintained a favourable ionic balance in terms of low Na+/K+ ratio resulting in good plant performance under salinity. The plants of NB-9 and CB-2 varieties did not survive at high salinity. Based on overall performance, NB-5 exhibited tolerance to moderately saline soils (ECe ~6.5dS m-1) and was successfully established when irrigated with normal water. |
