Patterns of Clone Growth in a Rare andEndangered Plant Potaninia mongolica Maxim

绵刺是阿拉善荒漠特有珍稀濒危植物 ,其具有独特的克隆生长构型 :由枝条下垂形成长间隔物的典型的游击型克隆生长构型和由根茎处形成的典型的密集型克隆生长构型。本文以环境塑造与克隆生长构型的可塑性关系研究绵刺的克隆生长构型 。

Potaninia mongolica Maxim is a specially rare and endangered plant in Alasan desert and has some special patterns of clone growth: the guerrilla pattern, which is made up of long dropping branch; the phalanx patterns, which composed of fraged root. This paper mainly discussed relations between alterative environment and adaptable pattern of clone growth, disclosed ecological strategy of Potaninia mongolica Maxim Adapting to the diversified environment.
