摘要:

介绍了植物茎的基本知识和变态类型；说明植物茎的变态实质上是植物为适应环境变化而产生的一种特殊的功能，这种变态具有稳定的遗传性；指出识别地下变态茎与地下根的关键在于茎上有节、节间、芽、叶痕，而根没有；识别地上变态茎与变态叶的关键则在于变态部位的来源和位置。

Abstract:

This paper introduces basic knowledge and morphological types of plaant stems,expounds that the modified stems of plants are essentially a special function produced by plants to adapt environmental change,which is stably hereditary,and points out that the key to the distinguishiableness of underground stems and underground roots is that stems have jounts,buds and leaf scars but roots do not have and that the key to the distinguishableness of modified stems and modified leaves on the ground lies in the differentitation of the sources and locations of the modified parts.
