摘　　要：绿萝是单子叶植物纲天南星科观赏植物,其茎的初生结构与禾本科植物茎显著不同.绿萝茎中维管束的分布分成2部分,一是靠近表皮的部分,排列呈一轮;另一部分则是在中心部分,大量维管束散生在基本组织中.因此,可用于观察和比较单子叶非禾本科植物茎的初生结构.以绿萝为实验材料可以开展多种实验设计,用于植物学实验中综合性实验内容的开展,锻炼学生的实践能力和创新思维能力.Epipremnum aureum is an ornamental plant in the Araceae family,class monocotyledons.The primary structure of the stem of Epipremnum aureum is significantly different from that of the gramineous plant.The distribution of the vascular bundle in the stem of Epipremnum aureum is divided into two parts.One is the part near the epidermis,which is arranged in a round.The other part is in the central part,where a large number of vascular bundles are scattered in the basic tissue.Therefore,it can be used to observe and compare the primary structure of the stem of non-gramineous monocotyledonous plants.A variety of experimental designs can be carried out with green plants as experimental materials,which can be used to carry out comprehensive experimental content in botany experiments,and exercise students′ practical ability and innovative thinking ability.
