摘要:

利用恒温基质繁育系统,开展微型月季‘丘比特’扦插繁殖技术试验,采用L9(34)正交试验设计,研究基质温度、微喷次数、微喷时间、激素处理4个因素对扦插生根效果的影响,以期建立微型月季‘丘比特’恒温基质扦插繁殖技术体系。综合分析平均生根率、平均根长、平均生根数3个生根效果指标,最优的水平组合为A3B2C1D1,即采用基质温度25℃、微喷2次、微喷时长5 min、IBA 200 mg/L浸泡10 min;本试验中最佳处理为T8处理,平均生根率达91.08%,平均根长5.17 cm,平均生根数6.36条。

Abstract:

The cutting propagation technology experiment of Rosa chinensis var. minima ‘Petit Four’ with constant temperature substrate breeding system has been done. The effects of substrate temperature, micro spraying times, micro spraying duration and hormone treatment on the cutting rooting were studied with orthogonal design L9(34), so as to improve the breeding technology system of Rosa chinensis var. minima ‘Petit Four’. The results showed that by comprehensively analyzing the average rooting rate, average root length and average rooting number, the optimal horizontal combination was A3B2C1D1, that is, the substrate temperature was 25℃, the micro spraying was 2 times, the micro spraying duration was 5 minutes, soaked with IBA 200 mg/L for 10 minutes. The best treatment in this experiment was T8 treatment, with an average rooting rate of 91.08%, an average root length of 5.17 cm, and an average number of 6.36 roots.
