桂树一枝多节,叶腋间有2～4个复芽叠生(图1),此特点在其他树种中少见。金桂、银桂、丹桂品种群的成龄枝贴靠枝梗的多是花芽,靠叶柄的多是枝芽(叶芽)。每个芽只有一个生长点:花芽开花;枝芽生枝,但实际上能生枝的仅为枝前端1～3节的4～6个芽。暂无能力萌发的,到4年以上,芽会自然脱落,呈隐芽。在实践中笔者惊奇地发现还有另一种隐芽存在:在我们能见到的那些叠生复 A branch of laurel tree, axillary axillary 2 to 4 complex bud overlay (Figure 1), this feature is rare in other species. Jin Gui, silver Gui, Dan Guargill species of adult branch stick mostly stems and branches are flower buds, mostly by the petiole buds (leaf buds). Each bud has only one growing point: flower buds bloom; branch buds grow branches, but in fact, branchlets are only 4 to 6 buds in front of 1 to 3 nodes. Temporarily unable to germinate, to 4 years or more, the bud will naturally fall off, was hidden bud. In practice, I was surprised to find that there is another hidden bud exists: in those we can see that the stack of complex
