为了研究TDZ在植物器官发生中的生理作用，用不同浓度的TDZ替代MS中的BA，发现仅用1／50BA浓度（0．1mg／L）的TDZ处理，已相当于用BA处理所得芽数，可见它具有很强的细胞分裂素活性；但是TDZ又能显著促进乙烯形成，较低浓度时抑制莴苣的器官发生，可能此时乙烯起着主导作用。
In order to study the physiological role of TDZ in plant organogenesis, TDZ was used instead of BA in different concentrations to find that TDZ treatment at a concentration of 1 / 50BA (0.1 mg / L) was equivalent to the number of shoots treated with BA , It shows that it has a strong cytokinin activity; but TDZ can significantly promote the formation of ethylene, lower concentrations inhibit lettuce organ development, ethylene may play a leading role at this time.
