Abstract

Abstract: At in vitro propagation of large2flowered hybrids of Cymbidium , cytokinins BA and KT are favorable to the induction of Protocorm Like-Body , but ZT does not , and cytokinins BA and auxin NAA all have significant effects on the induction and proliferation of ProtocormLike-Body , furthermore , BA has significant effect on the growth and proliferation of shoots. Low level of sucrose is required during induction of ProtocormLike Body and shoots differentiation. The key to rooting and strong sprout lies in suitable combination of GA and the banana mud.

Key words: Cymbidjium, In vitro culture, Protocorm Like-Body, Cytokinin, Auxin
