The influence of different irrigation conditions on flower bud development of the peach cv. 'Glohaven' was studied using scanning electron microscopy. The bud samples were taken every ten days from August 2 to October 2004-2005. Flower bud development under three irrigation treatments was compared. With optimum irrigation, T-1, trees were irrigated at approximately 100% ET. T-2 and T-3 trees received 50 and 20% of the water applied to the T-1, respectively. The rate of flowering at the stage of differentiation of sepal, petal, stamen. and pistil primordia was considerably slower at T-3 compared with T-2 and T, water. When water was not provided in the next year, flower bud initiation and differentiation was delayed. Results indicated that decreasing irrigation slowed the progression of flower initiation and differentiation.
