| 摘 要： | 利用正交试验法开展梅片树（Cinnamomum burmanni）嫩枝扦插繁育试验，旨在研究插穗类
型、生长调节剂种类及其质量浓度、基质类型等因素对梅片树扦插生根的影响。试验结果表明：插穗类
型、生根激素、激素质量浓度、扦插基质均会影响梅片树嫩枝扦插的生根性状，但影响程度存在差异；
生根率受插穗种类、生根激素、激素质量浓度、扦插基质 4 个因素影响，侧根数主要受到激素质量浓度
影响，不定根长主要受到激素种类、激素质量浓度及插穗类型影响。经比较分析，插穗类型采用带顶芽
茎段、生根激素使用 NAA : IBA=1 : 1 或 GGR、激素处理质量浓度为 100~150 mg/L、扦插基质使用黄心
土的生根效果较好，平均生根率达 88.15%，平均侧根数为 2.5 根，平均根长为 11.05 cm，根系发育较好。
因此在生产上梅片树扦插宜采用带顶芽茎段的插穗经 100~150 mg/L 的 NAA : IBA=1 : 1 组合或 GGR 浸泡
处理 3 h，选用黄心土基质进行扦插。

| Abstract: | The orthogonal experiment was used to carry out the shoot cutting of physiolgical type of
Cinnamomum burmanni. The aim was to study the effects of cutting type, growth regulator, concentration
and matrix type on cutting rooting of physiolgical type of C.burmanni. The results showed that the rooting
characteristics of cuttings of physiolgical type of C.burmanni were affected by four factors including cutting type,
rooting hormone, hormone concentration and cutting medium. The rooting rate was affected by cuttings type,
rooting hormone, hormone concentration , and rooting medium. The number of lateral roots was mainly affected
by hormone concentration. Adventitious root length was mainly affected by hormone type, hormone concentration
and type of cuttings. The comparative analysis result showed that the rooting rate of of budding stemstick with
NAA:IBA=1:1 or GGR(concentration is 100-150 mg/L) and cultured in yellow soil was higher than others, with
a average rooting rate reached 88.15%. The average number of lateral root was 2.5 and the average root length
was 11.05 cm. Accoring to the result, in order to obtain a good cuttage effect in the cultivation of C.burmanni it is suggested that the budding stemstick should be selected as the cuttings and soaked in 100-150 mg/L
NAA:IBA=1:1 or GGR for three hours, and then cultivated in yellow soil medium. |
