A Study of the Litsea coreana Cutting Propagation

A series of experiments of Litsea coreana cutting propagation were performed to select the appropriate kind of growth regulators and concentration, the suitable month and length for the Litsea coreana cutting propagation in Zhongli, Ya'an. And researches were made into the influnce of different growth regulators on the length and number of the Litsea coreana saplings' roots. The research results have shown that the best comprehensive effect is ABT(500 mg·L^-1), the most suitable cutting months are from Augest to October, and the most suitable cutting length is 5cm. Besides, the growth regulator of high concentration can promote the growth of root quantity, and the growth regulator of low concentration can promote the growth of root length.
