摘要：

本文在观察了代表22个族76个属的203种禾本科植物幼苗的发育过程和

各种性状的基础上，探讨了重要性状的形成与分布区、生境条件的关系及重要性

状之间的相关性。根据胚轴和根系发育的不同形式，将禾本科幼苗划分为三大

型：竹型、狐茅型和黍型。根据苗叶和不定根的特点，又把这些大型分为七个

亚型：真竹亚型、稻亚型、芦竹亚型、针茅亚型、狐茅亚型、画眉草亚型和真黍亚

型。经过与胚体和植株各方面数据的互相印证，证明与幼苗形态的七个亚型相

对应，在系统分类上是七个亚科：竹亚科、稻亚科、芦竹亚科、针茅亚科、狐茅亚

科、画眉草亚科和黍亚科。

Abstract:

Investigations have been made on the mode of development and various characteris-

tics of seedling of 203 grass species representing over 76 genera and 22 tribes. The

correlation between important characteristics and their main formative conditions in

distribution area and habitat were discussed. According to the various developmental

forms of the embryo axis and root system, the seedlings of grasses may be divided into

three main types: Bambusoid, Festucoid and Panicoid. And according to characteris-

tics of seedling leaves and adventitious roots, these types may be further divided into

seven subtypes: True Bambusoid, Oryzoid, Arundinoid, Stipoid, Festucoid, Eragrostoid

and True Panicoid. in this study, the different types of seedlings have been found to

be associated with other characteristics of embryo and adult plant; and on these

grounds, the genera of the Gramineae are grouped into seven corresponding subfa-

milies: Bambusoideae, Oryzoideae, Arundinoideae, Stipoideae, Festucoideae, Eragros-

toideae and Panicoideae.
