Effect of abscisic acid and kinetin on growth and proline accumulation in cacao seedlings under water stress*

The effect of exogenous ABA and kinetin applications on leaf expansion rate and proline contents was studied. The leaf growth was retarded during stress by ABA but recovery was faster after rewaterirtg. Leaf turgidity was also maintained by ABA and proline accumulation was lesser as compared to control showing lack of relation between RWC and proline content. Kinetin effect on these indicators was similar to those of control.
