本文首次采用三维和组织学相结合的方法，详细研究了葡萄属河岸葡萄自然种群的营养生长发育过程。未定型的原基（它可以发展成花序或卷须）和叶原基的启动记录和相关的原基启动周期中的位置。有四种可能的状态：（i）一片叶子在下卷须节上，它直接出现在一片叶子上方的圆顶形顶端的侧面;（ii）一片叶子在上卷须节或无卷须节上，它直接出现在卷须上方的宽顶端的侧面;（iii）一个较低的未定向原基，在顶侧非常高地出现，通过在顶的相对侧上的一个原基的起始而与下叶分开;和（iv）上部未定向原基，其产生于顶侧，通过在顶的相对侧上的两个原基的起始而与下叶分开。本研究表明，有证据支持的观点，即未定型原基是终端和侧。我们已经扩大了存在的卷须的葡萄属本物种的hydathodes的报告。腋芽的发生和发育与其他葡萄属的报道相同，每个冬芽都起源于前一个冬芽基生叶的腋部。
The vegetative development of natural populations of Vitis riparia is reported in detail for the first time, using a combination of three-dimensional and histological techniques. The initiation of both uncommitted primordia (which can develop into either inflorescences or tendrils) and leaf primordia is documented and correlated with their position in the primordium initiation cycle. There are four possible states: (i) a leaf at a lower tendril node, which arises on the flank of a dome-shaped apex directly above a leaf; (ii) a leaf at either an upper tendril node or a tendriless node, which arises on the flank of a broad apex directly above a tendril; (iii) a lower uncommitted primordium, which arises very high on the apical flank, separated from the subjacent leaf by the initiation of one primordium on the opposite side of the apex; and (iv) an upper uncommitted primordium, which arises on the apical flank, separated from the subjacent leaf by the initiation of two primordia on the opposite side of the apex. This study shows that there is evidence to support the view that the uncommitted primordium is both terminal and lateral. We have extended the reports of the presence of tendril hydathodes in Vitis to this species. Axillary bud initiation and development are the same as has been reported for other species of Vitis, with each winter bud being initiated in the axil of the basal prophyll of the previous one.
