摘　　要：对东方百合“索蚌Sorbonne”的几个主要性状的发育动态进行了研究。结果表明,进入拔节期后,节数、叶片数迅速增加,现蕾后节数不再增加,可见叶片数还略有减少。同时,从拔节期到现蕾期,地上部鲜重和干重、鳞茎的鲜重、干重及种球围径的变化动态都与现蕾到开花期不同;并对东方百合生长过程中鳞茎内淀粉含量和可溶性糖含量的变化进行了测定,鳞茎的淀粉含量先下降,花芽分化进程完成时达到最低,后开始增加。而可溶性糖的变化正好相反。Development dynamics of some important characters about Liliurn oriental ＂Sorbonne＂ was studied in this paper. The results indicated that the number of internodes and leaves increased rapidly in elongation stage, but no increase was found after showing flower buds, and that the number of effective leaves decreased in bud stage. The changes of fresh weight and dry weight of aboveground and the bulb underground from elongation to bulb stage are different from bud to flowering stage, and the bulb diameter different as well. The content of starch and soluble sugar in bulb were investigated during the growth season, results showed decreased significantly and reached the lowest value when the flower bud differentiation finished, then increased, while the dynamics of soluble sugar content just reverse.
