Osmotic regulation is a key mechanism by which tree adapts to water shortages resulting from an increased solute concentration of cells in order to maintain the water potential gradients needed to ensure continued uptake of water during the natural stress period of flowering and fruit growth (Saxena et al., 2011). Osmotic adjustment in leaves and roots enabled plant growth during periods with low soil water availability (Jones et al., 1980 and Morgan, 1984). The greater lowering of cell Ψπ and more osmotic adjustment in Amrapali as indicated in results thus is responsible for a high Ψw gradient between leaves and roots, allowing the tree to extract water from the soil even at very low soil Ψw values
