准确地鉴别苹果树的花芽和叶芽,对指导树体修剪、确保果树优质丰产是极为重要的。但是笔者在下乡时,发现一些果农尚不能准确鉴别苹果树的药芽和叶芽,这对果树修剪极为不利。下面,从芽体的外部形态和内部解剖构造两个方面做一介绍。 叶芽:芽体多瘦小且先端细尖,鳞片数少且抱合较松,手捏发软。外表茸毛多而长,发暗无光泽,芽体上无明显棱起,芽基粗而直立。剥去鳞片可见芽内有3—10个针刺状绿色嫩叶。

Hairy appearance and long, dark dull, no obvious bud body edge, bud-based rough and upright. Peel the scales visible buds have 3-10 needle-shaped green leaves.
