Abstract
Bloom foliar sprays of paclobutrazol (PB) at 2.5, 1.25 and 0.62 g a.i./L on avocado (Persea americana Mill, cv. Hass) trees reduced spring flush shoot length and redistributed dry matter among the components of fruiting shoots. There was an increase in the allocation of dry matter to fruit on treated trees with a corresponding reduction in the allocation to the stem and leaves. The spray treatments of 2.5 and 1.25 g a.i./L PB at bloom increased the mean fruit size at harvest by 16 and 11%, respectively. Fruit yield was not significantly affected by PB applications on an annual basis. However, the PB spray treatments of 1.25 and 0.62 g a.i./L significantly increased the two year cumulative yield by about 63%. In a second experiment, calcium concentrations in fruit from trees receiving a bloom foliar spray of 1.25 g a.i./L of PB were higher compared to fruit on untreated trees during the first 8 weeks after fruit set. The results are discussed in relation to yield and fruit quality management of cv. Hass avocados.
