海南黎药裸花紫株扦插育苗技术研究

为了建立高效的裸花紫株扦插育苗技术体系，从插穗年龄、粗度、生根药物处理等方面对裸花紫珠扦插育苗技术进行研究。结果表明：以2年生插穗的生根率最高，为38.6%，直径0.6~0.8 cm的插穗其生根率最高，为53.6%，所用生根粉均能显著提高生根率，其中以ABT7号生根粉效果最好，生根率最高为94.6%。插条年龄和插穗粗度对裸花紫株扦插生根率有显著影响，其中以直径0.6~0.8 cm 2年生插穗的生根率最高；ABT6、ABT7和ABD生根粉对裸花紫珠扦插生根均有明显的促进作用，其中以ABT7的生根效果最好。

Study on the Cutting Technology of Callicarpa nudiflora, A Medical Plant Used by the Li People in Hainan

In order to estimate the highly-efficient cutting technology for Callicarpa nudiflora. In the present study, the cutting technology of C. nudiflora was studied, including select the optimum age of cuttings, the cuttings diameter and study on the effect of rooting powder. The results showed that: the cuttings with two years old and 0.6-0.8 cm diameter had the highest rooting percent, up to 38.6% and 53.6%, respectively; the rooting percent could be remarkably increased by using the rooting powders studied, of which ABT7 was the best one with the highest rooting rate of 94.6%. The cutting age and diameter of C. nudiflora had significant effect on cutting rooting percent, which the cuttings with two years old and 0.6-0.8 cm diameter had the highest rooting percent; the cutting roots of C. nudiflora could be significantly promoted by the ABT6, ABT7 and ABD, of which ABT7 had the best effect.
