神农香菊表皮毛特征及腺毛分泌物成分1）

摘要

以原产于神农架地区的神农香菊为研究对象，采用荧光显微镜及电子显微镜观察神农香菊表皮毛结构及腺毛密度，通过GC／MS分析腺毛分泌物。结果表明：神农香菊表皮毛的主要类型分为不具有分泌功能的T型非腺毛、具有分泌功能的头状腺毛。神农香菊叶片分别生长到3、4、5个月时，头状腺毛密度分布规律由多到少分别体现为上部叶、中部叶、下部叶；中部叶、上部叶、下部叶；中部叶、下部叶、上部叶。花部腺毛分泌物主要为α－蒎烯、β－蒎烯、α－水芹烯、双戊烯、樟脑、合成右旋龙脑等。%With Dendranthema indicum var.aromaticum in the Shennongjia area , we used fluorescence microscope and electron microscope to observe trichome and trichome density , and analyzed the glandular hairs secretions by GC /MS.The main types of trichomes of D.indicum var.aromaticum were T type non-glandular with a secretory function , and capitate glandu-lar hairs with a secretory function .When the leaves of D.indicum var.aromaticum were grown to 3, 4 and 5 months, the capitate glandular trichome density distribution in descending order were upper leaves , middle leaves and lower leaves;middle leaves , upper leaves and lower leaves;middle leaves , lower leaves and upper leaves , respectively .The glandular in the flower secretions were α-pinene,β-pinene,α-phellandrene, dipentene, camphor, and synthetic borneol .
