Cultivar differences were not found significant in sugar accumulation during non-stress and stress periods. However, 6.2% to 16.3% increase in sugar accumulation was observed during stress period compared to non-stress period. Similarly free amino acid accumulation increased by 38% during stress period as compared to non-stress period. Drought tolerant types accumulated more of these solutes than the susceptible types during severe stress condition. Association of these solutes in the osmotic adjustment of the crop is discussed by working out correlations. The results indicated that osmotic adjustment plays an important roljp in the drought tolerance mechanism in coconut.enAmino acidcoconutosmotic potentialsugarArticle
