| 摘 要： | 紫苏叶上有两种腺毛：质状腺毛和头状腺毛。两者都具１个基细胞、１个柄细胞和头部。前者的头部可由１、２、４或８个分泌细胞组成，扩展成质状；后者的头部由１、２或４个分泌细胞组成，聚成圆球状。两种腺毛的原始细胞都来源于原表皮细胞，经两次平周分裂产生基细胞、柄细胞和顶细胞。在腺毛后期的形态发生中，柄细胞的分化状态决定腺毛的类型。若柄细胞保持扁平关且处于分生状态时，其顶细胞将发育成质状腺毛的头部；若柄细胞纵向

| Abstract: | The leaves of Perilla frutescens (L. ) Britton beared two types of glandularhairs,peltate and capitate, which comprised one hasal cell,one stalk cell and one head.The head of peltate glandular hairs consisted of one,two, four or eight secretory cellsand was peltate--shaped while that of capitate glandular hairs was composed of one,two,or four secretory cells and was globose-shaped. The initial cells of both types of glandular hairs originated from the protodermal cells and created a hasal cell,a stalk cell and anapical cell through two successive periclinal divisions. During the late stage of the morphogenesis of glandular hairs,the type of glandular hairs was affected by the differentiation degree of the stalk cell. The apical cell would develop into the head cells of peltateglandular hairs if the stalk cell kept meristematic and flat--shaped. The apical cell woulddevelop into the head cells of capitate glandular hairs if the stalk cell rapidly enlargedlongitudinally and was of vacuolization. |
