Water stress and dormancy release in flower buds of Coffea arabica L.: water movements into the buds

Using tritiated water and Ca as tracers, the effect of the subtendin leaf and of water strees on the movement of water and calcium to flower buds of coffee during dormancy release was studied. Either the subtending leaf or water stress enhanced the movilization of water and calcium towards the flower buds. The movilization of water and calcium to buds was greater in plants that had experienced a drought period. A water strees period is apparently essential to release the buds from dormancy, but neither the subtending leaf for the water potential gradient from leaf subtending the flower bud clearly affected the phenomenon
