野生硫磺百合（Lilium sulphureum）是一种具有重要药用价值和观赏价值的植物，其珠芽可作为无性繁殖的手段。本研究以硫磺百合珠芽的发育为研究对象，通过形态学观察和解剖学研究，硫脉石蒜的珠芽最早出现在叶柄基部的腋部，它起源于亚基细胞，小珠的发育过程可分为触发期、膨大期和成熟期3个阶段，成熟的小珠一般为球形或椭圆形，内细胞中含有大量的淀粉粒作为贮藏同化物，小珠的萌发率很高（90%），说明小珠的营养繁殖是适应生态环境的重要途径。
The wild Lilium sulphureum,an important plant species that has medical and horticultural values,possesses bulbils as vegetative propagation.In this current work,we focused on the develpment of bulbil for L.sulphureum.Based on the morphological observation and anatomical study,the bulbil formation of L.sulphureum was identified.The bulbil was firstly appeared on the basal site of petiole in the axil.It originated from cells of sub-epidermal of petiole.The process of bulbil development could be divided into three stages:triggering phase,expanding phase,and ripeness phase.The maturated bulbils generally are spheral or ellipsoidal.The inner cells posses large mount of starch granule as storage assimilate.The germination rate of L.sulphureum bulbils is very high(90%).This result showed that vegetative propagation of bulbils is an important way for ecological adaptation.
