Abstract:
In order to screen suitable bud-cutting and shoot-promoting methods for ‘Mid-Autumn King’ apple,juvenile branches of 3-year-old trees of Malus pumila ‘Middle-Autumn King’ were treated with different ways including bud-notching all (T1),bud-notching in lower (T2),middle (T3) and upper (T4) parts of a branch,and no bud-notching was used as control to study the relationship between branching power and sprouting in branches.The results showed that bud-notching could significantly increase the germination and sprout rate (P<0.05),and germination rate was extremely significantly and positively correlated with sprouting rate (P<0.01),and negtively correlated with short shoot rate (P<0.05),and significantly positively correlated with long shoot rate (P<0.05).Bud-notching had remarkable effects on germinating,sprouting and branches composing and bud-notching in middle was the best way to improve the germination and sprout rate when we comprehensively considerate the germinating and sprouting effects,shaping effects and time and labor saving effects in apples.
