| 摘 要： | 对40株文冠果实生植株果实的主要经济性状进行了测定分析,并对其进行了主成分分析和综合指数评价。结果表明:文冠果果实以小球果型最多,占总样本的40%,97.5%样本种仁含油率在60%以上,种子出仁率平均为51.22%,果实出籽率平均为47.13%。果实性状发生不同程度的变异,其中变异系数最大的是结果数量,为32.25%,变异系数最小的是种仁脂肪含量,为3.99%。由各单株的综合主成分值选出的综合经济性状优良的单株与其实际表现近似。 |
| 关 键 词： | 文冠果 经济性状 主成分分析 优株选择 |

| Abstract: | The main fruit economic characters of 40 seeding plants of Xanthoceras sorbifolia were determined and studied by principal component analysis,and the composite indices of the fruits were also evaluated.The results indicated that the small-cone-type fruits accounting for 40% of the gross sample possessed the maximum proportion among all the fruits of Xanthoceras sorbifolia.The oil content of 97.5% samples was over 60%.The kernel ratio was 51.22%,and the average seed ratio per fruit was 47.13%.There were different degrees of variations between fruit characters,and the variation coefficient of fruit yield per tree was the biggest as 32.25%,while that of the total fat content of kernel was the smallest as 3.99%.The single plants with good comprehensive economic characters were selected according to the principle component values and performed similar to their actual. |
