It is of great practical significance to study the development process of cut lily for regulating flowering and preservation. In this study, the developmental process of lily cut flower was explored from cellular, morphological, and physiological aspects. From a morphological aspect, the tepal edge grows faster than the midrib. The midrib groove of the flowering stage is wider than that of bud stage. The fast-growing edge of the petals results in the midrib bending outward. Moreover, the rapid growth of the stamens and stigmas also contributes to bud cracking. From the cellular aspect, in the bud stage there were more wrinkles in the outer epidermal cell wall of the tepal than those in the inner epidermal cell wall, indicating that asymmetric structural differences exist from the beginning of lily development. From a physiological aspect, from the bud cracking stage to the senescence stage, a variety of substances in the tepal cells gradually decreased, including total nitrogen, total phosphorus, total potassium, total calcium, starch, soluble sugar, and soluble protein, but not malondialdehyde. These results indicate that the asymmetric growth caused by this structural difference is responsible for flowering. The wrinkles in the cell wall can be regarded as indicators of senescent cells and are caused by the degradation of the cell wall and the loss of intracellular turgor pressure. The differences in the epidermal cells between the inner and outer tepal indicated ultrastructural changes in the tepal cells. The bud and flowering stages are maintained by the tepals acting as a sink. After flowering, the tepals gradually change from a sink to a source organ. Senescence of the cut lily flowers was caused by the decomposition of intracellular compounds in the tepals and the remobilization of nutrients from the tepals to the developing organs.

研究切花百合的发育过程对调控开花和保鲜具有重要的现实意义。在这项研究中，从细胞，形态和生理学方面探讨了百合切花的发育过程。从形态学的角度来看，花果边缘的生长速度快于中脉。开花期的中肋沟比芽期的中脉沟宽。花瓣快速生长的边缘导致中肋向外弯曲。此外，雄蕊和柱头的快速生长也有助于芽裂。从细胞方面来看，在花蕾期，花被的外表皮细胞壁上的皱纹要多于内表皮细胞壁上的皱纹，这表明从百合发育开始就存在不对称的结构差异。从生理的角度来看，从芽破裂阶段到衰老阶段，花被膜细胞中的多种物质逐渐减少，包括总氮，总磷，总钾，总钙，淀粉，可溶性糖和可溶性蛋白质，但不包括丙二醛。这些结果表明，由这种结构差异引起的不对称生长是开花的原因。细胞壁中的皱纹可以被认为是衰老细胞的指示，并且是由细胞壁的降解和细胞内膨胀压力的损失引起的。内和外花被之间的表皮细胞的差异表明花被细胞中的超微结构改变。花被作为水槽，维持花蕾的萌芽和开花期。开花后，花被逐渐从下沉变成源器官。
