摘　　要：目的:考察植物叶表皮微形态特征在鉴别天南星科植物的可行性及其分类学意义。方法:运用光学显微镜对天南星科21种植物叶表皮的微形态特征进行观察,对特征进行拍照、描述、绘图及数据测量,并利用SPSS 26.0软件对所得数值进行统计分析。结果:本研究中采集的天南星属、半夏属、海芋属、犁头尖属及魔芋属共计21种植物叶表皮细胞垂周壁弯曲程度、细胞大小、气孔器大小等微形态特征均存在差异。结论:叶表皮微形态特征与统计学方法结合可作为部分天南星科植物的分类鉴别依据。Objective:To investigate the feasibility and taxonomic significance of leaf epidermal micromorphology in the identification of Araceae plants.Methods:Leaf epidermal micromorphological characteristics of 21 species of Araceae plants were observed with optical microscope.The characteristics were photographed,described,drawn and measured.The obtained values were statistically analyzed by SPSS 26.O software.Results:In this study,there were differences in the bending degreeof the anticlinal wall,cell size,stomata sizeand other micromorphological characteristicsof leaf epidermal cellsin 21 species of Arisaema,Pinellia,Alocasia,Typhonium and Amorphophallus.Conclusion:The combination of leaf epidermal micromorphological characteristics and statistical methods can be used as a basis for the classification and identification of some Araceae plants.
