Effects of ABA on the content of four different types of starch in banana fruit were studied with‘Brazil'banana as the tested materials at 20 days after emergence from the pseudostem(DAF) and 60 DAF by 0.5 mmol/L ABA treatment. The results showed that the color of banana peel was greenish yellow, and the starch granule characteristics had no obvious change compared with the control(water treatment). However, the content of total starch, amylose, and resistance contents in fruit were decreased by 1.0%, 8.18%, and 0.39% respectively,and the amylopectin content was increased by 7.18%. At edible stage, compared with the control, the content of total starch and amylopectin in the ABA treatment group were increased by 0.88% and 0.5%, respectively.Amylose and resistant starch content were decreased by 1.97% and 5.24%, respectively. Correlation analysis indicated that ABA treatment before harvest was closely related to the content of different starch, and the correlation coefficient was r=0.829 0, which was not significantly different.
