摘　　要：本文对毒莴苣、莴苣、宿根莴苣、苦莴苣、山莴苣、雀苣的种子、植株及种子表面细微结构的形态进行了比对分析。结果表明:在种子的外观形态上,毒莴苣与莴苣相似,与其他种子区别较大;在植株形态上,山莴苣、莴苣、宿根莴苣、毒莴苣的根、茎、叶均区别较大,容易区别;借助扫描电镜对莴苣、毒莴苣、苦苣、山莴苣、宿根莴苣、雀苣种子的表皮纵棱个数、纵棱形态及表皮花纹的观测表明,毒莴苣与其近似种之间存在较大差异,有利于鉴别到种。Comparative studies on morphological characteristics of Lactuca serriola, Lactuca sativa, Lactuca perennis, Lactuca virosa, Lactuca indica and Lactuca viminea based on seed morphology, plant morphology, and micromor-phological character of the seeds surface. The result showed that Lactuca serriola was generally similar with Lactuca sativa but varied greatly among other different species in seed morphology. According to the root, stem and leaf morphology, it was found that there are no close relations between Lactuca serriola and its close relative species. Furthermore, there were significant differences in the numbers of longitudinal ridge, morphological characteristics and the surface figure of seed epidermis among different species.
