为改良紫珠属植物的园林性状，以白棠子( Callicarpa dichotoma)和紫珠( C. bodinieri)为亲本，对结实特性、杂种子代性状进行了研究。结果表明，白棠子和紫珠不存在孤雌生殖现象，自交不结实，天然杂交结实率分别为93.08%和98.08%。人工杂交座果率最高可达95.24%，但果实在发育过程中易受到外界环境的影响导致结实率降至26.21%~37.07%。部分子代的叶片形态介于父母本之间，初步证实了杂种的真实性。白棠子×紫珠组合的杂种子代在株高、冠幅及一级分枝数的变异系数分别达到118.96%、125.06%和130.62%，远高于反交组合子代。因此采用白棠子为母本、紫珠为父本更易获得具有特殊性状的子代，为良种的选育奠定基础。

To improve landscape characteristics in genus Callicarpa plants, the pollination, fruit develop-ment and progeny characteristics were investigated using C. dichotoma and C. bodinieri as parents. Results showed that no parthenogensis existed and no fruits obtained from the inbreeding of two tested species. The fruit setting ratio of C. dichotoma and C. bodinieri in natural crossing was up to 93. 08% and 98. 08%,respectively. In artifi-cial crossing,the fruit setting ratio of 95. 24% could be obtained but it decreased to 26. 21%-37. 07% during fruit development for external injury. The availability of successful crossing was confirmed from the leaves mor-phology of offspring varying between the parents. The coefficient variation in plant height,crown,and quantity of primary branches of offspring plants of C. dichotoma×C. bodinieri was up to 118. 96%,125. 06% and 130. 62%, respectively,much higher than that of the counter-junctions combination. Excellent offsprings could be obtained easily using C. dichotoma as female parent and C. bodinieri as male parent.
