摘要: 采用常规石蜡切片法及扫描电镜技术对木香薷(Elsholtzia stauntoni Benth)腺毛发生发育及其规律进行了研究。结果表明:木香薷表皮上主要有两种表皮毛:无分泌细胞的表皮毛与有分泌细胞的腺毛。前者包括单细胞乳头状毛、2~3细胞管状毛、分枝状毛及多细胞管状毛;后者包括头状腺毛与盾状腺毛。成熟头状腺毛头部由1、2或4个分泌细胞构成,头部呈圆球形或半圆球形;成熟盾状腺毛头部由8~12个分泌细胞构成,分泌细胞横向扩展形成盾状头部。木香薷腺毛主要在茎端幼叶处大量发生,从茎端第一对幼叶处开始产生;从幼叶期到成熟期均有腺毛发生,大部分腺毛在幼叶期发生发育,只有极少部分在叶的成熟期进行发生发育。

关键词: 木香薷, 腺毛, 发生, 发育规律

Abstract: The paraffin sectionning and scanning electron microscopy (SEM) were used to study the morphogenesis and law of development of Elsholtzia stauntoni Benth. The results showed that glandular hairs of E.stauntoni Benth has two main types of trichomes: trichomes without secreting cells and trichomes with secreting cells. The former include: single-cell mastoid trichomes, 2-3 cells tubular trichomes, 2-3 cells ramose trichomes and multicellular tubular trichomes. The latter include peltate and capitate hairs. The mature capitate glandular hairs comprise one, two or four secretory cells and its head is spherical or half spherical. The head of mature peltate glandular hairs comprises eight to twelve secretory cells and the secretory cells expand to a shield-shaped head. The glandular hairs of E.stauntoni Benth mainly occur greatly on younger leaves and start to generate from the first pair of younger leaves of stem apex. The morphogenesis of new glandular hairs can be observed to occur from young leaves stage to mature stage, however, only a relatively small amount occurs in maturation stage.

Key words: Elsholtzia stauntoni Benth, glandular hairs, morphogenesis, law of development
