dc.description.abstractHybrid seedling combinations comprised of three Dwarfs (COD, CGD and MYD) each crossed with three Tails (WCT, FMS and Fiji) were evaluated based on. proline accumulation capacity under induced stress condition (by air desiccation) as well as recovery potential of the seedlings after relief from moisture stress under field condition. Leaf water potential (0taJ was determined during non-stress, stress and recovery periods. Seedling combinations did not show significant differences in 0leqf during both non-stress and stress periods. However, proline concentrations showed significant differences between the seedling combinations as well as between the treatments. The interaction between seedling combinations and the treatments was also found to be significant. Correlation worked out between the 0, ,and the proline concentration did not show any relationship. Recovery of the seedlings after relief from stress indicated that among the seedling combinations CGD x WCT, CGD x FMS and MYD x WCT are comparatively more tolerant to water stress than the others. Proline accumulation capacity did not show any relationship With the recovery potential of the seedlings. This implies that leaf proline concentration is not a good indicator of leaf water status in coconut.en_US
