| 摘 要： | 探索不同枝条年龄和生长调节剂对藤茶(Ampelopsis grossedentata)扦插的影响,找出最适合扦插的枝条年龄以及生长调节剂种类和浓度。结果表明,藤茶一年生枝条各项生长指标都高于二、三年生枝条,大量生产时应选用一年生枝条作插穗;用20 mg/kg吲哚丁酸处理藤茶一年生枝条,其不定根长度、发芽数、高生长、生物量、成活率表现最优,用40 mg/kg吲哚丁酸处理藤茶一年生枝条,不定根上发出的侧根数最多。从总体上分析,生产中用20 mg/kg吲哚丁酸处理藤茶一年生健壮枝条效果最理想。

| Abstract: | To explore the age and growth regulators on its influence in the process of cutting Ampelopsis grossedentata, main-ly in order to find the most suitable cutting branches of the age and the type and concentration of growth regulators. The re-sults showed that the growth index of annual branches of the A. grossedentata were higher than the two or three year old branches,a large number of production should select annual branches as cuttings;when treating A. grossedentata annual branch with 20 mg/kg IBA,the performance of adventitious root length,germination,growth,biomass,high survival rate are optimal,when treating A . grossedentata annual branches with 40 mg/kg IBA,adventitious roots from the lateral root number got most. From the overall analysis,20 mg/kg IBA treatment for annual robust branches of A. grossedentata is most ideal in production. |
