Effects of IAA and BA on Tissue Differentiation of the Girdled Stem in Jerusalem Artichoke

Xu Xin and Li Zheng-li (Lee Cheng-lee)   

Abstract: The stem of Jerusalem artichoke (Helianthus tuberosus L.) reacted variably when treated with IAA and BA after girdling. Formation of calli on the girdled surface of xylem was promoted but the production of periderm was retarded when it was treated with suitable concentrations of IAA and BA. However, the comparatively high concentrations of IAA and BA also accelerated the differentiation of callus into vascular tissues and eventually formation of new rind.

Key words: Jerusalem artichoke, Regeneration, IAA, BA
