百合鳞茎发育生物学研究进展

Advances in the developmental biology of lily bulb

百合是重要的鲜切花,也可以做盆花,还可以在园林中应用。要生产出优质的百合切花,需要优良的百合种球,生产出优质种球需要对百合鳞茎的发育生物学深入了解。在阐述了百合鳞茎生长发育特点的基础上,对其生长发育过程中重要的生理生化变化进行了综述,其中包括鳞茎中淀粉含量变化、淀粉代谢的关键酶、可溶性糖及蛋白质的相关研究进展,并就今后鳞茎发育研究趋势进行了展望。

Lily （ Lilium spp. ） is an important cut flower species, and it also can be raised as potted flower and used in landscape horticulture. To produce nice lily flower, high quality lily bulbs are needed and the understanding of its developmental biology is absolutely necessary. This paper reviews the important physiological and biochemical changes in the process of bulb development, including recent progress on the concentration change of starch, key enzymes （such as amylase） during the metabolism of starch, soluble sugars and proteins in lily bulbs. The prospect of further research on the metabolism and accumulation of nutrients, the regulation of endogenous hormone or enzymes activities for bulblet differentiation and bulb development were discussed.
