在长江中下游地区的长江周边、太湖西苕溪、赣江中上游低山丘陵建立 4处试验林 ,包含种源试验林、种源 /家系二水平试验林。通过种源试验 ,4个试验点各选出优良种源 6个。研究表明 ,种源与地点交互作用达到极显著水平 ;生长优良且具较高稳定性的种源有福建邵武、广西全州、贵州铜仁、道真、湖南郴州、湖北蒲圻 ;幼年期香樟树高、胸径生长与经度呈极显著负相关 ,冻害与纬度呈极显著负相关。香樟幼年期种源 /家系二水平试验表明 ,余杭试验点和遂川试验点不同性状在家系间差异显著 ,种源层次的方差分量大大高于家系层次。根据家系的生长和适应性表现 ,选出了 36个优良家系 ,树高增加 10 %～ 4 9% ,地径增加 10 %～ 84 %。根据香樟适应性和生长表现 ,进行种源区划分 ,将香樟种源区划分为北带种源区 (Ⅰ )、中部种源区 (Ⅱ )和南带种源区 (Ⅲ )。
In the middle and lower reaches of the Yangtze River in the vicinity of the Yangtze River, the Taihu Lake Xitiaoxi, the middle and upper reaches of the Ganjiang River hilly four experimental forests, including provenance, provenance / family two levels of experimental forest. Through the provenance test, 4 test sites each selected 6 elite provenances. The results showed that the interaction between provenances and sites reached an extremely significant level. The provenances with high growth and high stability were Fujian Shaowu, Quanzhou in Guangxi, Tongren Guizhou, Daozhen, Chenzhou in Hunan and Putian in Hubei; , DBH growth and longitude showed a significant negative correlation, freezing damage and latitude showed a significant negative correlation. Cinnamomum camphoraceae germplasm resources / family two level test showed that the Yuhang experimental point and Suichuan experimental point of different traits significant differences in the pedigree, the source level of the variance component is much higher than the family level. According to the growth and adaptability of the pedigree, 36 elite pedigrees were selected. The tree height increased by 10% ~ 49% and the diameter increased by 10% ~ 84%. According to the adaptability and growth performance of camphor, the division of provenance region was divided into three types: the provenance zone (Ⅰ), the central provenance zone (Ⅱ) and the southern provenance zone (Ⅲ).
