多花山竹子扦插繁殖技术研究
On Cuttage Seedling Technique of Gareinia Multiflorm Champ.ex Benth.Khamp
【摘要】 对多花山竹子扦插育苗采用L16(45)正交试验设计法,探讨不同插穗类型、激素种类浓度及扦插基质对多花山竹子在平均生根率、平均根系数及平均苗高上的影响差异。结果表明:采用无顶芽主枝及无顶芽侧枝作为插条,置于300μg/mL的IBA中浸泡1h,而后扦插于腐殖质土中,平均生根率高达92.3%且苗木生长发育情况最佳。对各因素处理水平进行多重比较显著性检验,试验结果表明,激素浓度是影响其平均生根率的最主要因素,且该试验结果表现为5%水平上差异具有统计学意义。
【Abstract】 By adopting L16(45) orthogonal test in cuttage seedling of Gareinia multiflorm Champ.ex Benth.Khamp,an experiment was conducted to probe how the different cuttings,hormone concentration and base material of cottage influence the seedling’s average rooting rate,rooting coefficient and seedling height.The results of the experiments are as follows:Adopt apical-bud-removed bough and apical-bud-removed lateral branch as cuttings,for one-hour soak in 300μg/mL IBA then to stick in humus soil,the average rooting rate reach up to 92.3% and the nursery-grown plants grow best;hormone concentration is the most significant factor and there is a significance level of difference which is 5%.
