Abstract:

Through 3 times introduction of rare C. controversa Hemsl during 20 years, it has proved that the C. controversa Hemsl can be successfully introduced in Wuhan region with considerable volume of fast growing. The average annual height growth can be up to 89 cm during seedling period in that year. However, for big tree, to 1. 2 meter and 1.12 cm for the breast diameter growth, which greatly surpass those of Phoebe shearer and Magnolia denudata, and other rare species and have very high value of development and utilization.
