摘　　要：早在16世纪,植物学家就开始研究维管束植物的幼苗。1825年—1826年De Candolle就强调过幼苗形态对豆科分类的意义。由于幼苗形态在系统分类研究中是一个很重要的特征,同时在植物系统发育的研究中也有重要作用。因此,幼苗形态这一特征作为系统分类的一种工具已被愈来愈多的分类学家所重视。本文回顾了幼苗研究的简史,并就下列几个问题进行了讨论:①幼苗形态与正确鉴定植物;②幼苗形态与某些分类群再划分:③幼苗形态与某些亚科的合理区分;④幼苗形态与论证某些植物类群的系统位置。根据上述的讨论,笔者认为幼苗形态在植物系统分类学上是一个重要的特征。Early in the sixteeting century, botanists began to study the seedlings of vascular plants. De Candolle (1825—26) stressed the value of seedling morphology for the taxonomy of Leguminosae. The seedling morphology is the most important role in the study of phylogenetic relationships of plants, therefore,current botanists renewed the interest in seedling morphology, the application of this character state as a systematic tool.In the paper, the study history of seedling is reviewed and folloowing problems are discussed; (1)Seedling morphology and correct identification of plants; (2) Seedling morphology and subdivision of some taxa; (3) Seedling morphology and reasonable division of some subfamillies; (4) Seedling morphology and in relation to the systematic position of some plant groups. According to the discussion above, we consider that seedling morphology is one of the important characteristics in plant systematics.
