莲属（Nelumbo）包括两个种：莲属（N. nucifera和N. lutea n.荷花是一种观赏和食用植物，被广泛种植。早期的圣莲研究（N。nucifera）花主要集中在形态、叶序、叶排列和花发育。在生长季节，神圣的莲花在每个节点产生一片叶子。花芽从叶基部的背面出现。然而，盛开的花朵的数量远远少于叶子的数量。关于莲属植物发育过程中花芽的形成知之甚少。这是首次通过实验研究揭示了即使在休眠的茎尖，每个节上也有一个花芽，并且大多数形成的花芽在花发育过程中败育。我们的研究结果表明，圣莲的花芽形成是独立的日照。另一方面，形成的芽是否达到开花可能取决于环境因素。
The genus Nelumbo consists of two species, N. nucifera and N. lutea. N. nucifera is an ornamental and edible plant that is widely cultivated. Earlier studies of sacred lotus (N. nucifera) flowers focused mainly on morphology, phyllotaxis, leaf arrangements, and flower development. During the growing season, sacred lotus produces one foliage leaf at each node. Flower buds emerge from the abaxial side of the basal part of the foliage leaf. However, the number of blooming flowers is much less than the number of foliage leaves. Little is known concerning flower bud formation during lotus plant development. This is the first experimental study to reveal that every node has one flower bud even in the dormant shoot apex and that most of the formed flower buds aborted in the course of floral development. Our results suggest that flower bud formation of sacred lotus is independent of daylength. On the other hand, whether a formed bud reaches blooming may depend on environmental factors.
