| 摘要: |
| 光皮树是我国新发掘的一种珍稀、优质、理想的多用途乡土木本油料树种，尤其适合石灰岩山地种植，是石漠化地区良好的生态恢复造林树种。根据2008年和2010年对粤北地区（主要在乐昌县境内）进行的两次资源调查结果，发现粤北地区光皮树资源亟待保护。现存光皮树的分布类型主要包括：（1）树龄在200年以上的散生古树、；（2）天然小群体和；（3）人工小群体三种类型。以生长和果实产量为主要目标经济性状，共收集粤北地区光皮树种质资源45份。根据文献资料以及最新试验数据，文章对光皮树这一珍贵树种的开发利用进行了总结和探讨。 |

| Abstract: |
| Cornus wilsoniana Wanger is a new unearthed rare ideal native woody oil tree species with high quality and multi-purpose, particularly suitable for limestone area reforestation. According to the survey results of germplasm resources of Cornus wilsoniana in north Guangdong area (mainly in Lechang county territory) in 2008 and 2010, we think they should be protected urgently in this area. Existing tree distribution type mainly includes: (1) Old tree with age of over 200 years old; (2) Natural small population. (3) Artificial small population. Based on the main target economic characters of growth and fruit yields, Seeds and stocks of 45 selected individuals of Cornus wilsoniana were collected. According to the literature and latest data, the development and utilization of Cornus wilsoniana were summarized and discussed in this paper. |
