摘要： 研究旨在通过对比‘欧石楠’插穗在不同处理下的生根差异，揭示欧石楠插穗的生根规律，从而为进一步完善欧石楠繁殖体系提供理论依据，为其实践生产提供技术支持。在全光照自动喷雾控温大棚内对欧石楠插穗进行不同激素浓度、不同基质、不同插穗类型及不同扦插时期的处理，对插穗的生根率、平均根数、平均根长及生根质量进行LSD及one-way ANOVA分析。欧石楠插穗在1000 mg/L的IBA影响下生根率最高，达到82.43%，且与其他浓度相比差异显著(P<0.05)；在椰糠与珍珠岩（椰糠:珍珠岩=3:1）混合基质中，其插穗的各项生根指标均优于其他基质中的插穗；半木质化插穗是最适宜扦插的类型，较其他类型而言，其生根率、平均根数、平均根长达到显著水平(P<0.05)，生根质量达到极显著水平(P<0.01)；9月份扦插，插穗的生根率可达94.2%。本试验明确了适宜欧石楠插穗生根的激素浓度、基质及插穗类型、扦插时期。

Abstract: Through comparing the rooting difference of Erica carnea cutting in different treatments, the rooting law of Erica carnea cutting was revealed, in order to provide theoretical basis for the propagation system of Erica carnea and technical support for production practice. Hormone concentrations, cutting periods, matrix types and cutting positions were investigated in the full-light, automatic-spray and temperature-control greenhouse. Least significant difference (LSD) multiple comparisons and one-way ANOVA were applied to analyze the rooting rate, average root number, average root length and the rooting quality in different treatments. The rooting rates reached 82.43% when the shoot was soaked with 1000 mg/L IBA which had significant effect on rooting rate contrasted with the other two levels (P<0.05); the best composition of matrix for softwood cutting should contain 3 parts of coconut tree branny and one part of pearlite; there were significant differences in the rooting rate, root number, and the root length among different types of cutting positions (P<0.05), while an extremely significant level was observed in rooting quality (P<0.01). The best type of cutting position was semi-lignified branches. The rooting rate was 94.2% in September. The appropriate hormone concentration, matrix type and cutting position, cutting period were proved in this study.
