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。
In this paper, we compared and analyzed the morphologies of the fine structure of the seeds, plants and seeds on poisonous lettuce, lettuce, pea, lettuce, lettuce and currant. The results showed that: the appearance of the seeds, the toxic lettuce and lettuce similar to other big difference between the larger; plant morphology, mountain lettuce, lettuce, peach lettuce, poisonous lettuce roots, stems, leaves are large and easy The differences of the number of longitudinal edges, the longitudinal rib shape and the epidermis pattern of lettuce, toxic lettuce, bitter lettuce, mountain lettuce, pea lettuce and cedar seed by scanning electron microscopy showed that there was a significant difference between the virgin lettuce and its approximate species Differences, is conducive to identify species.
