苹果的花芽,因其在枝条上的着生部位,常分作顶花芽和腋花芽两种。着生于果枝顶端的叫作顶花芽。着生于枝条侧面,由腋芽形成的花芽,叫作腋花芽。一般顶花芽的芽子饱满,较大,顶端较圆钝。鳞片间包被较紧密,鳞片较光亮,少茸毛。金帅、国光等品种的顶花芽,芽基与枝条相接处,稍收缢而现略细,芽子稍向一侧歪斜,鳞片间有黑褐色线纹,青香蕉的顶芽较大,有时一些分化不完全的“中间芽”,从外观上,往往容易与花芽混同起来。在这种情况下,可以用刀片将芽子纵向切开,借助于手持扩大镜辨认。有些苹果品种,如祝、金帅,富士等,容易形成一定数量的腋花芽。这对于增加幼树的早期产量,具有一定的意义。腋花芽较叶芽肥大、凸起,鳞片色较深而光亮,在修 Apple flower buds, because of its placement in the branches of the branches, often divided into top flower buds and axillary buds two. Born at the top of the fruiting branch is called the top flower buds. Born on the side of the branches, buds formed by axillary buds, called axillary buds. Top buds generally top bud full, larger, blunt top. Scales between the package is more closely, scales more bright, less hair. Jin Shuai, Guoguang and other varieties of the top flower buds, buds and branches at the junction, a little twitch and now slightly smaller, buds slightly skewed side, between the scales dark brown lines, the top of green banana bud larger, Sometimes, some incompletely differentiated “middle buds” tend to be confused with flower buds from the outside. In this case, the blade can be cut vertically with the aid of a hand-held magnifying glass. Some apple varieties, such as wish, Jinshuai, Fuji, easy to form a certain number of axillary buds. This is of great significance for increasing the early yield of saplings. Axillary buds buds hypertrophy, bulge, darker scales and bright color, in repair
