摘　　要：利用光学显微镜对药用植物藿香（Agastache rugosa）叶片表皮毛被类型和分布进行了研究。结果表明：藿香的叶表皮有3种形态显著不同的毛,包括非腺毛、盾状腺毛和头状腺毛。腺毛和非腺毛在叶片的上下表皮都有分布。腺毛的发育在叶片发育早期就已经完成,其密度随着叶片的发育而减小。盾状腺毛和头状腺毛都具1个基细胞、1~2个柄细胞和头部。成熟的盾状腺毛的头部由12个分泌细胞组成;头状腺毛头部由1或2个分泌细胞组成。The morphology and distribution of leaf trichomes of Agastache rugosa were studied using light microscopy.The result showed that there were three morphologically distinct types of trichomes on Agastache rugosa leaf surfaces：non-glandular,peltate and capitate glandular.The glandular and non-glandular trichomes presented on both the adaxial and abaxial surfaces.The growth of trichomes had completed in the early stage of leaf growth,its density was decreasing with the density of leaf growth.Peltate and capitate glandular trichomes comprised one basal cell,one or two stalk cells and one head.The head of mature peltate glandular trichomes consisted of twelve secretory cells while that of capitate glandular hairs was composed of one or two cells.
