Abstract: The seedling breeding experiment of Davidiai involucrata was conducted with different seed treatment methods and varied substrates in the mountainous area. It was indicated by the results that:Low temperature stratification with river sand in the open air could promote seedling emergence rate by 17.1% compared to the method of burying the seeds in cattle manure. The seedling emergence rate by sowing in the autumn was 14.6% higher than sowing in the spring. Humus substrate could increase the height growth and basal diameter growth by 59.3% and 41.6% respectively than those of regular sand substrate. The best seedlings of D. involucrata were bred at elevation range between 1250m and 1500m. Adventitious roots could take place on cuttings prepared from spring shoots with secondary sprouts, while there were no adventitious roots taking place from cuttings made of the autumn shoots.
