大叶紫珠和小紫珠的扦插繁殖技术

目的]为大叶紫珠和小紫珠的快速繁殖提供有效的途径。方法]以生长健壮、无病虫害的大叶紫珠、小紫珠半木质化枝条为材料，以清水处理为对照，研究500、1000mg／t萘乙酸（NAA）和500、1000mg／L吲哚丁酸（IBA）处理对枝条平均生根率、最长根长和平均生根数的影响。结果]经NAA和BA处理后，大叶紫殊扦插的生根率、最长根长、生根数得到了显著提高，1000mg／LNAA处理的生根率最高（比对照高20％）；小紫珠扦插的生根率、生根数得到了显著提高，不同处理之间差异相对较小，综合考虑各项指标，500mg／L IBA处理对其效果最好。结论]该试验筛选出了对大叶紫殊的小紫珠的扦插最有利的处理方式，为大叶紫珠和小紫珠的快速繁殖提供了有效的途径。

Research on Cutting Propagation of Callicarpa macropylla and Callicarpa dichotoma

Objective ] The aim was to provide an effective way for rapid propagation of Callicarpa macropylla and Callicarpa dichotoma. Method] With healthy C. macropylla and C. dichotoma semi - lignified branches as the materials and treatment with clean water as CK, the effects of 500, 1 000 mg/L naphthalene acetic acid （NAA） and 500, 1 000 mg/L indole butyric acid （IBA） on rooting rate, max root length and root number were studied. Result ] The rooting rate, max root length and root number of C. macropylla and C. dichotoma were greatly improved with the treatment of NAA and IBA. The rooting rate of C. macropylla branches was the highest （ being 20% higher than that of CK） with the treatment of 1 000 mg/L NAA and the treatment of 500 mg/L was most suitable for the cutting propagation of C. dichotoma. Conclusion] The best treatment was obtained from the test and this will provide an effective way for the rapid propagation of C. macropyUa and C. dichotoma.
