The results showed that the juvenile phase could be shortened by more than two years when 2-year seedlings were grafted on the dwarf stocks. The effects of P22 and SH3 were significantly different. Grafted on P22, the flowering node was less, the first flowing site was lower, and the juvenile phase was shorter than SH3. With the two stocks, the average first flowering site was more than 200 cm, the average flowering node was more than 100, and the lateral branch top bud was more than 50% in all first flowing seedlings.展开更多
