Advances in the developmental biology of lily bulb
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.
