聚合草有许多芽始终不发育,有的只能发育成穗,但是可以用于繁殖。这些芽是茎生叶腋芽和丛生叶腋芽。一株两年生的聚合草上有十几个茎生叶腋芽和二百个左右的丛生叶腋芽,用这些芽繁殖,比现有的用根段、茎段和叶柄繁殖出苗快,比用根颈繁殖倍数显著提高。一、腋芽的形态丛生叶腋芽:在每个丛生叶基部的内侧有一个腋芽,形如舌尖,大小如削下的火柴头,或象半个小米粒,紧贴在叶的基部不易看到(下称嫩叶芽)。外周老叶死后,老叶的叶腋芽增大,有的能大如扁火柴头。剥去死叶基部后即裸露在外面(下称老腋芽),见照片1。茎生叶腋芽:茎生叶的叶腋处
Polygrasses have many buds are always undeveloped, and some can only grow into spikes, but can be used for breeding. These buds are stem leaves axillary buds and clusters of axillary buds. A biennial aggregated grass has more than a dozen stem axillary buds and about 200 axillary bud clusters, with these buds than the existing roots, stems and petioles to reproduce faster emergence than the root Neck multiplication significantly increased. First, the axillary bud clusters clumps axillary buds: in each clump leaf base inside an axillary bud, shaped like a tongue tip, the size of the matchsticks head cut, or like half a grain of rice, close to the base of the leaf is not easy to see ( Hereinafter referred to as young buds). After the death of the old peripheral leaves, old axillary bud leaves increased, and some can be as big as flat matchstick head. Peel off the base of the dead leaves that are exposed on the outside (hereinafter referred to as the old axillary buds), see photo 1. Stem leaves axillary buds: cauline leaf axils
