Litsea cubeba, the aromatic litsea or may chang, is an evergreen tree or shrub 5–12 meters high in the family Lauraceae. It is native to China, Indonesia, Taiwan and other parts of Southeast Asia. It is called "mountain pepper" (山胡椒) in Mandarin and maqaw (馬告) by the Atayal aborigines in Taiwan. It produces a fruit which is processed for its lemony essential oil. The oil can also be extracted from the leaf, but this is considered to be lower in quality. The timber is sometimes used for making furniture and crafts. Plant parts are also used in medicine.

A tissue culture and rapid propagation method of litsea cubeba with effectively reduced browning and improved rooting rate

PendingCN122349983ABrowningSeedling
This invention discloses a rapid propagation method for Litsea cubeba tissue culture that effectively reduces browning and improves rooting rate. The method selects healthy, young stem segments of Litsea cubeba as explants, sterilizes them, and inoculates them into a primary induction medium to induce initial bud formation. These are then inoculated into a subculture proliferation medium to obtain subculture clusters of buds. Single buds are then cut and inoculated into a rooting medium for dark culture to induce rooting. Finally, the seedlings are hardened off and transplanted to obtain tissue culture seedlings ready for nursery. This invention solves the problems of low subculture proliferation coefficient and severe browning by optimizing the explant sterilization measures, the primary induction medium, the subculture proliferation medium, and the rooting medium formulation, reducing the explant browning rate to below 5.0%. Simultaneously, the subculture yields a large number of clustered buds in a short time with a high proliferation coefficient; the tissue culture seedlings have more than four roots, resulting in a high rooting rate; the transplant survival rate is high, and the seedling quality is good. This reduces the industrial-scale production cost of Litsea cubeba tissue culture seedlings and provides technical support for large-scale seedling production and artificial cultivation of Litsea cubeba.
