Abstract: The results of experiment for years and at many places showed that spraying ‘Zhuangguoshu’ (a nutritive compound growth regulator) solution 5-7 days after banana (Musa acuminata cv. Dwarf Davendish) buds cutting off gave remarkable effects on improving growth and increasing yield of the fruits. The fresh weight, pulp weight, dry matter and starch accumulation rate in pulp increased synchronously with the rate of fruit growth, and there was not any adverse effect on the appearance and quality of banana fruit.
