Van der Muelen 等(1939—1952)曾研究了咖啡花芽和花序的发育。咖啡花芽通常在叶腋形成并丛生,而多数植物的花芽为单生。每个叶腋可形成5个芽。最大的芽离茎最近,最小的芽靠近苞叶叶柄。随着枝条的生长和顶芽叶片的展开,在枝梢节的芽原基就显现。一个副芽发育成花序还是营养枝,要待该芽达到一定的发育阶段才能确定。在这个阶段,如果诱导开花的条件占优势,其后就有一个扁平的顶端生长锥分裂成两 Van der Muelen et al. (1939-1952) studied the development of coffee flower buds and inflorescences. The flower buds of coffee are usually formed and clustered in the axils of the leaves, while flower buds of most plants are solitary. Each leaf axils can form five buds. The largest buds are removed from the stems lately, the smallest buds close to the leafhopper petiole. With the growth of shoots and the development of the top bud leaves, shoot primordia appear at shoot shoots. A paw developing into inflorescences or vegetative branches, to be the bud to reach a certain stage of development can be determined. At this stage, if the conditions that induce flowering are predominant, then a flattened top growth cone is split into two
