Southwest Forestry University successfully established the Japanese wild sumac tree micro-propagation technology system

China News Service, Kunming, October 5 (Zong Dan He Chengzhong) The reporter learned from Southwest Forestry University on the 5th that with the funding of the Yunnan Provincial Forestry Science and Technology Promotion Project, the research team of Southwest Forestry University is working in the field of Japanese wild sumac micro-propagation technology.
A breakthrough has been made
.

According to reports, the research team further optimized the rooting technology of the axillary buds of Lacquer sylvestris, and successively created rooting induction technologies such as "rooting to promote rooting", "root bark extract to promote rooting", and "care and culture to promote rooting", making the rooting time from 45 days.
Shortened to 12 days, the rooting rate reached more than 95%, which greatly increased the rate of seedling formation, and provided technical guarantee for seedling cultivation for the construction of the clonal raw material forest of this tree species
.

The lacquer tree is named after it produces lacquer
.

Japanese lacquer is an excellent germplasm of lacquer tree that has been oriented for hundreds of years by Japanese breeders to produce lacquer wax as the breeding goal
.

Due to the high content of urushiol and other secondary metabolites, China's introduced cultivation areas have not yet been able to solve the problem of asexual reproduction and seedling technology of Japanese lacquer, and the species has serious pistil abortion.

In response to the urgently needed asexual propagation and seedling technology needs in production practice, Professor He Chengzhong of Southwest Forestry University led a research team.
