- 摘要:
- 以采自西藏9个不同区域的光核桃果实和种子为试材，对其果实的宽、扁、纵径以及果肉厚和]种子的宽、扁以及纵径共7项形态学指标进行了测量，研究了其表型性状及变异特点。结果表明：果实表型性状，果实性状间的变异系数为6.62%～9.54%，种子性状间的变异系数为7.27%～0.35%，对果实表型性状的方差分析P值均小于0.05，种子宽、扁的P值小于0.05，表明光核桃种子的表型性状变异是其变异的主要来源。
- Abstract:
- With nine different walnut(Prunus miakoehne) from the Tibet as materials，the main measures which were the fruit of the wide，flat，vertical diameter and thick pulp and seed of the wide，flat and the longitudinal diameter of a total of indices of physical morphology were determined,and phenotypic characters of fruit and seed and its variability were studied.The results showed that，fruit phenotypic traits and fruit traits 6.62% to 9.54%，the variation coefficient of seed traits 7.27% to 10.35%，the variation coefficient of variance analysis of the fruit phenotypic traits P values were less than 0.05，seed width，flat P value was less than 0.05，it showed that the phenotypic traits of the seed were the main source of variation to prunus miakoehne.
