摘　　要： 对使君子插穗扦插后的生根及生长能力与插穗年龄、插穗长度、扦插时间、生根促进剂和扦插基质等相关因素进行了研究。结果表明 :①扦插后 65d开始形成不定根 ,为愈合组织生根为主的综合生根类型树种 ;②插穗年龄、插穗长度、扦插时间、生根促进剂和扦插基质对插穗的生根及生根能力具有显著或极显著的影响 ;③在扦插繁殖中 ,宜采用 2年生已充分木质化 1 6cm长的插穗 ,用 1 0 - 4 g·mL- 1 质量浓度的萘乙酸浸插穗基部 2 4h ,黄心土 +火烧土 +细河沙 +过磷酸钙 (5∶3∶1∶1 )为基质 ,3月扦插。表 5参 This study was made in the Nursery of Fujian College of Forestry in 1998.The research results indicated that there were significant and greatly significant effects of cutting age,cutting length,cuttage time,root growth helping maters and cuttage substrate on the rooting and growth ability of Quisqualis indica of 10 year old.Cuttings could not grow the adventition roots until 65 d after cuttage.The cutting propagation techniques are as follow:the base ends of cuttings of 2 year old with the length of 16 cm were infused in the NAA solution with the concentration of 10 -4 mg·L -1 for 24 h,and planted in the comprehensive cutting substrate(loess∶burned soil∶river sand∶superphoshate=5∶3∶2∶1)in March.
