新梢的节部稍膨大,节上着生叶片,叶互生.叶腋内着生芽眼.叶片的对面着生卷须或果穗.新梢叶腋的芽眼着生有两个芽(夏芽和冬芽).随着新梢的加长生长,叶腋的夏芽即自然萌发成夏芽副梢;夏芽的边上是冬芽,冬芽在一般情况下需经越冬至第二年春才能萌发. The shoots of the shoots are slightly swollen with nodes of leaves growing on opposite sides of the leaves, with sprouting eyes in the axils, raw tendrils or ears opposite the leaves, buds of the axils of the shoots have two buds (summer buds and winter buds). With the growth of new shoot growth, leaf axillary summer bud that naturally sprouted into summer buds shoots; summer buds are winter buds, winter buds in winter under normal circumstances to the second year of spring to germination.
