Role of Thidiazuron in Plant Tissue Culture

Abstract

Thidiazuron (TDZ) is a synthetic plant growth regulator affected to plant growth like cytokinin. TDZ could induce multiple shoots, flower bud,callus, and somatic embryo in many plant species with low concentration when compared with other cytokinin. The effectiveness depends on TDZ concentration, plant species and of explants. TDZ could induce indig-enous auxin cytokinin level in plant tissue and then induce plant development. Exteamly high concentration of TDZ resulted in decrease shoot robustness, percent of root formation, and normal development of somatic embryo. The role of TDZ was detailed in this review.
