摘要：

探讨接骨木嫩枝扦插繁育技术,对开发利用这一珍贵植物具有重要意义。以2~3年生接骨木半木质化枝条为扦插材料,采用3因素3水平正交试验设计,研究GGR6、NAA、IBA 3种生长调节剂的不同浓度及处理时间对接骨木嫩枝扦插的影响。生长调节剂以IBA的处理效果最好,平均生根率达86.67%,与GGR和NAA处理下的平均生根率差异显著,而GGR6与NAA的效果差异不大。在处理时间上,以0.25 h的效果最佳,平均生根率达85.00%,其次为1 h（生根率82.22%）,这两者之间差异不显著,处理0.5 h时平均生根率最低(71.67%)。各处理的新枝叶片数、抽枝长度及生根数差异均达到了极显著水平(P<0.01),根长之间的差异达到了显著水平(P<0.05)。利用隶属函数法,对各处理下接骨木的生根率、新枝叶片数、抽枝长度、根长及生根数进行综合评价,结果表明,100 mg/L IBA处理1 h虽然综合评价结果排名第三,但其生根率显著高于综合评价值,且并列第一,更适合在生产中推广应用。

Abstract:

It is of great significance to explore the softwood cutting propagation technology of Sambucus williamsii for its development and utilization. Taking 2 to 3-year-old semi-lignified branches of S. williamsii as the cutting materials, the effects of different concentrations and treatment time of 3 growth regulators GGR6, NAA and IBA on softwood cutting of S. williamsii were studied by using three-factor and three-level orthogonal design. The results showed that IBA was the best growth regulator with the average rooting rate of 86.67%, which was significantly different from that of GGR and NAA, but the effect difference of GGR6 and NAA was not significant. As to the treatment time, 0.25 h was the best with the average rooting rate of 85.00%, followed by the 1 h treatment with a rooting rate of 82.22%, there was no significant difference between these two treatments, and the average rooting rate under 0.5 h treatment was the lowest, which was 71.67%. The differences of the number of leaves of new branches, the length of branches and the number of roots were extremely significant under different treatments (P<0.01) and the differences of root length were significant (P<0.05). The rooting rate, the number of new branches and leaves, the length of branches, the length of roots and the number of roots of S. williamsii were comprehensively evaluated by using the membership function method, and the result showed that 100 mg/L IBA treatment for 1 h ranked the third in the comprehensive evaluation, but its rooting rate was significantly higher than that of comprehensive evaluation index and ranked in joint first place. Therefore, 100 mg/L IBA treatment for 1 h is more suitable for popularization and application in production.

Key words: Sambucus willamsii, softwood cutting, growth regulator, rooting rate, the number of roots, root length
