Abstract

The invention discloses an induction culture medium for callus of an endangered hemimangrove plant tung paulownia and application of the induction culture medium to tissue culture of the hemimangrove plant. The invention also discloses a culture method of the callus of the endangered semi-mangrove plant tung paulownia and application of the callus to tissue culture of the semi-mangrove plant. According to the induction culture medium and the culture method, the callus of the semi-mangrove plant paulownia fortunei can be efficiently cultured, the survival rate of callus culture is remarkably improved, the callus yield is high, the browning rate is low, the pollution rate is low, and technical support for seedling culture and propagation is provided for solving the endangered problem of the species.

Description

technical field [0001] The invention relates to the technical field of tissue culture, in particular to an inducing medium, a culture method and application of callus of the endangered semi-mangrove plant A. chinensis. Background technique [0002] Lithium alba is a semi-mangrove plant belonging to the genus Lithocarpus, which is often used for windbreak and sand fixation. It is an important component tree species for coastal protection and has important ecological protection value. Liu Liping, Wu Yinsheng and others conducted research and analysis on the components of the branches and seeds of A. chinensis, and found that they are rich in various substances such as lignans and alkaloids that resist cancer, tumors, leukemia and other diseases, so it also has important medicinal value. However, in the state of natural reproduction, the reproductive capacity of wild lotus leaf trees is extremely poor, and there is a situation of abortion. It has been unable to reproduce normal...
