摘要
本文对12种国产楤忽木属药用植物的花粉和叶片进行了描扫电镜和组织解剖学研究,结果表明楤木属植物花粉表面纹饰除已发现的网纹型外,尚具脑纹型和中间过渡类型,花粉特征和某些形态相近种有分类价值;种间叶表特征差异较大,叶下表面特征可分为两类:楤木型和长刺楤木型,综合运用这些特征对于该植物种的鉴定是有价值的。
The authors made a detail study on pollens and leaves of 12 medicinal species of Aralia distributed in China, and found that besides reticulate type, the ornamentation of pollen grains from Aralia have other two types,i. e. regulate type and interm type. Pollen surfacial features could not beused as the stand and for identifying species, but to some morphologicallysimilar species they are of taxonomical significance; SEM feature diffe-rences of leaves among species vary greatly, comprehensive utilization ofthose characteristics may provide the method for identification of Araliaspecies.
