摘要
Cinnamomum micranthum is one of China Third-class Endangered Tree Species. The seedlings of C. micranthum are difficult to obtain. It is important to study the cutting propagation of C. micranthum in different seasons to improve the rooting rate for providing seedling propagation technique for the afforestation industry. In this study,the optimal season for the cutting propagation of C. micranthum was summer( May),providing 80. 6% rooting rate. The rooting rate in Summer was 33. 4% higher than that in Spring( March). This technique is important to make the best use of rare C. micranthum resources and to provide plenty of seedlings for afforestation and greening industry.
