以经过选优确定的8株4-松油醇型白千层优株为试验材料,采用同一基质、同一生根促进剂及同一浓度的单因子试验方法,研究了不同时间、不同插穗以及不同优株对扦插生根成活率的影响。试验结果表明,在1、2、3、4、11、12月扦插其生根成活率平均可达45.6%以上,其它月份扦插生根成活率很低,只有5%～0;同一优株不同插穗生根成活率差异不大;不同优株其扦插生根成活率差异显著,生根成活率最高的是28号优株,平均生根成活率达到86.9%～91.9%,扦插生根成活率最低的是34号优株,平均生根成活率仅有32.1%～37.8%.本试验研究结果对生产上进行4-松油醇型白千层优良种源的无性繁殖具有重要意义。
Eight selected 4-terpinen-rich Melaleuca alterniflora as tested materials were selected to study the effects of different time, different cuttings and different superiority on the same substrate, the same rooting accelerant and the same concentration of single factor test method Effect of Strain on Survival Rate of Rooting. The results showed that the rooting survival rate of cutting could be up to 45.6% on average in 1, 2, 3, 4, 11 and 12 months. The survival rate of cuttings in other months was very low, only 5% ~ 0. There was no significant difference in survival rate between the two groups. The survival rate of different superior plants was significantly different from that of rootstocks. The highest survival rate of rootstock was 28th excellent strain, and the average rooting survival rate reached 86.9% ~ 91.9%. The lowest rooting survival rate was 34th excellent strain , The average rooting survival rate was only 32.1% ~ 37.8% .The results of this study on the production of 4-Terpineol Melaleuca seed provenance of asexual reproduction of great significance.
