Conteúdo: | The effect of 4 different levels of water stress on the balance of vegetative and reproductive activity of 'Valencia' orange trees were compared. Irrigation was withheld after the end of the rainy season allowing the soil to dry out to matric potentials of -0.07, -0.16, -0.18 and-0.32 MPa which produced predawn leaf water potentials of -0.45, -0.50, -0.65, and -0.85 MPa, respectively. Vegetative activity following rewatering was higher in trees that had undergone lower water stress. Values of 23.1, 44.7 and 51.2% of nonbearing shoots were produced in the wettest treatment in the growth flushes of February, April and July, respectively, vs. 13.2, 24.4 and 20.2% in the driest one.
