Abstract
Fruit drop is a serious problem in plum trees during fruit development after pollination and fertilization. In order to increase fruit yields, physiological fruit drop in plum trees at the early stages of fruit development must be reduced. In this study, the effect of gibberellic acid paste (GA paste 2.7%) applied on 'Formosa' plum was determined to reduce fruit drop. GA paste was applied one time on one set of the fruit stalk at 3 days after full bloom (DAFB), and on another set of the fruit stalk at 13 DAFB, and then the fruit-set rate was observed at 70 DAFB. GA paste application increased the fruit-set rate up to 61%. In 'Formosa', the time of GA application had a strong influence on reducing fruit drop. GA application increased the fruit-set rate up to 61% in treatments at 3 DAFB, and to 15% in treatments at 13 DAFB when the fruit-set rate was 5% in the control group. The same results were observed in 'Honey Red' and 'Akihime' plums. GA application impacted on fruit enlargement in the 'Formosa' cultivar, compared with the control trees, which had no GA application. The rate of fruit enlargement with GA application was similar to that of the control fruits until 70 DAFB, whereas the enlargement rate was slightly higher in the GAtreated trees than the control from 70 DAFB until harvest. In GA-treated fruit, fruit weight increased more than in the control, while total acidity and firmness was lower than in the control group. Additionally, GA application accelerated sucrose increase in maturing fruit. Our data indicated that GA paste application can reduce fruit drop, and subtly promote fruit enlargement and maturation in plum trees.
