不同因素对高粱泡扦插生根的影响

Effects of Different Factors on Rooting of Rubus lambertianus Cutting

[目的]开展高粱泡扦插繁殖试验。[方法]采用正交试验设计方法,以植物生长调节剂、扦插基质、插穗类型和处理时间为影响因子,开展高粱泡扦插繁殖试验。[结果]植物生长调节剂处理高粱泡插穗,插穗生根率、平均根数、平均根长、生根质量均明显高于清水对照组。萘乙酸(NAA)处理对高粱泡插穗生根率具有明显的促进作用。插穗类型对高粱泡生根率、平均根数、生根质量的影响最大,而扦插基质对高粱泡平均根长的影响最大。从总的生根质量来看,当插穗类型为顶芽茎段、扦插基质为菜园土、萘乙酸(NAA)浓度为300mg/L、处理时间为2h时,高粱泡无性繁殖的生根效果最好。[结论]该研究为高粱泡种苗提供了一种高效的繁殖方法。

[Objective]To carry out the experiment of Rubus lambertianus Ser.cutting propagation.[Method]Orthogonal experiment design method was adopted to carry out the experiment of R.lambertianus cutting propagation with plant hormone,cutting matrix,cutting type and treatment time as the influencing factors.[Result]Rooting rate,average root number,average root length and rooting quality of R.lambertianus cuttings treated with plant hormones were significantly higher than those of the control group.NAA treatment significantly promoted rooting rate of R.lambertianus cuttings.The rooting rate,average rooting number and rooting quality of R.lambertianus were significantly affected by the type of cuttings,while the rooting substrate had the largest impact on the average rooting length of R.lambertianus.In terms of the total rooting quality,when the cutting type was the terminal bud stem segment,the cutting substrate was vegetable soil,the NAA concentration was 300 mg/L,and the treatment time was 2 h,the rooting effect of R.lambertianus asexual propagation was the best.[Conclusion]This study provides an efficient propagation method for rapid propagation of R.lambertianus seedlings.
