| description | mango (Mangifera indica) and citrus (Citrus sinensis L) plants in the greenhouse. Under gradually decreasing
soil moisture content, mango and citrus differed in their leaf water potential, stomatal conductance, leaf growth
and peroxidase activity. Stomata of both plants responded independently to the changes in leaf water potential as
soil drying progressed. The reduction in stomatal conductance in mango was greater than citrus suggesting that
citrus was able to control water loss better than mango to the changing condition of water availability in the root
zone. Peroxidase activity increased significantly in water stressed citrus plants. There was a 6-10 fold increase in
proline content when both species were exposed to water stress. Citrus plants accumulated higher proline levels
suggesting that they can tolerate water stress compared to mango. This was also evident by a faster recovery after
rewatering in citrus compared to mango plants that involved regeneration of new shoots. |
