据观察,有些苹果品种如国光、金帅、青香蕉等,由骨干枝的延长枝剪口下的侧芽发生的旺枝,其基部常有付芽存在。付芽即为枝条芽鳞痕下的芽;由芽子最外两片鳞片腋间发生。它对枝条的更新有重要作用。另一些品种,如红玉、秋花皮等付芽较少。同一株树上,生长旺的枝比生长弱的枝付芽多。此外,国光、金帅、青香蕉等品种的旺枝疏剪时,在枝条基部残存0.5-0.7厘米的短桩时,常会由此短桩上发育不充实的小侧芽即“瘪芽”或付芽发出更新枝来。这种更新枝对防止骨干枝光、秃及形成果枝有重要作用。为了解不同品种付芽与瘪芽的发生情况及利用问题,于1962-1965年在莱阳对山东栽培较普遍的10个品种(国光、青香蕉、红香蕉、白粉皮、金帅、祝光、祥玉、新红玉、秋花皮、红玉)进行了研究,现将结果简报于下:
It has been observed that some apple varieties such as Guoguang, Jin Shuai and Qing Ban Ban, etc., have their buds present at the base of their branches which extend from the lateral buds under the branches of the trunk branches. Bud bud is shoots buds under the branches; buds from the outermost two scales axillary occurred. It has an important effect on the update of the branches. Other varieties, such as red jade, fall flowers and other buds to pay less. On the same tree, branches growing more than branches growing weak branches buds. In addition, Guoguang, Shuai Shuai, green banana and other varieties of Wang sparse pruning, the remaining 0.5-0.7 cm at the base of the short pile, often short stubble on this short pile is the development of “bud bud” or pay Buds issue newer branches. This renewed branch has an important role in preventing the sticking of branches, baldness and the formation of fruiting branches. In order to understand the occurrence and utilization of different varieties of buds and buds, ten cultivars (Guoguang, Qing bananas, red bananas, white peels, Jinshuai, ZhuGuang, Xiang Yu, new ruby, autumn flower skin, ruby) conducted a study, the results of the briefing now:
