| 摘 要： | 对鸡爪绵核桃坚果质量和坚果三径的变异及相关性进行研究。结果表明：鸡爪绵核桃果实形态在采样点间及采样点内均存在着显著差异。3个采样点间果实总体变异幅度最大的是坚果质量10．55-21．05g（变异系数CV为13．44％），其次是纵侧径比3．03～4．44（变异系数CV为8．31％），侧横径比的变异幅度最小0．92～1．23（变畀系数CV为4．50％）；采样点内变异幅度最大的是坚果质量，最小的是侧横径比。不同采样点间坚果横径与侧径呈紧密线性相关，坚果的质量与坚果3径均达到极显著线性相关，可根据多元回归方程对坚果质量进行预测。

| Abstract: | The samples were collected from the main distribution area of the Jizhaomian--Walunt, and the variation and correlativity of nut weight and three diameters were studied. The result showed that there were significant differences in Jizhao- mian--Walnut fruits among and within three producing areas. The greatest variation among the three producing areas was the nut weight at 10.55 to 21.05 gram （CV was 13.44%）, followed by the nut longitudinal diameter and side diameter ratio 3.03 to 4.44 （CV was 8.31%）. The nut side diameter and the nut transverse diameter ratio was 0.92 to 1.23 （CV was 4.50 %） which was the smallest of all. Within the producing area, the maximal and minimal variation coefficients were still the nut weight and the nut side diameter and transverse diameter ratio. Significant linear correlation was found between the nut side diameter and transverse diameter of Jizhaomian--Walnut within different producing areas. The three nut diameters were all significantly correlated with the nut weight within every producing area. So, the nut weight was predictable. |
