为进一步优化1.5代杉木种子园的质量,通过对福建漳平杉木种子园内21个杉木无性系生长和球果特征的调查,分析不同无性系生长和结实性状的差异及其相互关系,采用层次分析法对不同无性系的生长性状和结实性状进行综合评价。结果表明:1.5代杉木种子园不同无性系之间的生长和结实性状存在明显差异;不同无性系的结实量、球果体积、球果鲜重与其种子产量显著相关,生长性状与结实量、结实量与种子发芽率的相关性不显著。根据不同无性系生长性状和结实性状的综合评价结果,有6个无性系具有生长快且结实量高的特性,可作为重建1.5代杉木种子园的材料。
為進一步優化1.5代杉木種子園的質量,通過對福建漳平杉木種子園內21箇杉木無性繫生長和毬果特徵的調查,分析不同無性繫生長和結實性狀的差異及其相互關繫,採用層次分析法對不同無性繫的生長性狀和結實性狀進行綜閤評價。結果錶明:1.5代杉木種子園不同無性繫之間的生長和結實性狀存在明顯差異;不同無性繫的結實量、毬果體積、毬果鮮重與其種子產量顯著相關,生長性狀與結實量、結實量與種子髮芽率的相關性不顯著。根據不同無性繫生長性狀和結實性狀的綜閤評價結果,有6箇無性繫具有生長快且結實量高的特性,可作為重建1.5代杉木種子園的材料。

In order to further optimize the quality of 1.5-generation seed orchard, the growth and setting characteristic of 21 Chinese ifr (Cunninghamia lanceolata) clones in 1.5-generation of seed orchard at Wuyi State-owned Forest Farm, Zhangping, Fujian Province, were investigated, and the difference and relationship of growth and setting characters among clones were analyzed. The characters of growth and setting of 21 clones was comprehensively evaluated by the analytic hierarchy process (AHP). The results showed that there were significant differences in growth and setting characters among different clones in 1.5-generation seed orchard. There was significant correlation between seed yield and setting amount, volume, fresh weight of cone, but no signiifcant correlation between growth characters and cone setting amount, seed germination rate, respectively. According to the comprehensive evaluation on growth and setting characters of different clones, 6 clones of Chinese fir were selected owing to fast-growing and high seed yield. It was suggested that they could be used as materials for reconstruction 1.5-generation seed orchard of Chinese ifr.
