Tóm tắt

The banana fruit reached its maximum size in terms of length and diameter at 18 weeks of age. The content of chlorophyll a in banana peel reached the highest value at 14 weeks old, chlorophyll b content reached the highest value at 12 weeks old and decreased rapidly. The content of carotenoid was low from fruit formation and then increased rapidly until the fruit is fully ripening. The vitamin C content and total organic acid content reached a maximum at 16 weeks old and then decreased until the fruit is fully ripened, the reducing sugar content increased continuously and reached a maximum at 18 weeks old and then decreased slightly. The starch content and pectin content reached a maximum when the fruit was 14 weeks old and then gradually decreased. The tannin content decreased from fruit formation until fruit ripening. Through the research process, we found that banana achieves the best quality to harvest when fruits are 18 weeks old. The results of this study provide important data for the harvesting and storage of banana fruit.
