目的:為山東產(chǎn)木賊科草藥經(jīng)典分類提供屬種間形態(tài)解剖學(xué)依據(jù)。方法:采用光鏡和掃描電鏡對(duì)山東產(chǎn)2屬5種1變種木賊科草藥進(jìn)行了形態(tài)解剖學(xué)的研究。結(jié)果:木賊屬和問(wèn)荊屬在氣孔類型、氣孔保衛(wèi)細(xì)胞表面附屬物及內(nèi)皮層層數(shù)等方面有顯著差異;山東木賊科植物維管束內(nèi)均有側(cè)生木質(zhì)部。結(jié)論:依據(jù)莖的內(nèi)部結(jié)構(gòu)和表面特征可將它們進(jìn)行屬間分類,但屬內(nèi)種間差異較小

The morphology and anatomy of two genera, five species and one variety of Equisetaceae produced in Shandong Province were studied under light and scanning electron microscope There are remarkble differences between Equisetum L. and Hippochatete Milde in the type of stomas, attachments on the surface of stoma guard cells and the number of epithelial layers; and the presence of lateral xylem in all vasular bundle of Equisetaceae from Shandong. The results showed that they can be identified taxonomically according to their inner structual and epidermal characteristics of stem between different genera, but with little difference among species of same genus
