Nowadays, because of many reasons ,this species is on the verge of extinction . In order to protect this species , the main content of this paper is that we take advantage of cuttage propagation technology to research cuttings by choos- -ing different concentrations of indole acetic to process it . At last , observing and comparising of rooting , to explore the most appropriate indole acetic acid concentration of rooting. Key words : Hande liodendron bodinieri; Cutting propagation; Indole acetic acid; Root situation 1.前言 1.1掌叶木的研究现状 掌叶木( Hande liodendron bodinieri ) 俗称鸭脚板、平舟木,属无
