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.
