| 摘 要： | 为深入研究亚热带地区薰衣草无性繁殖方法,验证在南方地区建立薰衣草育苗基地的可行性,在南宁地区研究了不同基质、枝条部位、IBA浓度和处理时间对齿叶薰衣草、甜薰衣草和羽叶薰衣草扦插成活效果的影响。结果显示,甜薰衣草扦插成活效果要显著优于齿叶薰衣草和羽叶薰衣草,河沙和珍珠岩可作为薰衣草的扦插基质,枝条中部作插穗成活效果更佳,而IBA处理浓度和时间对不同薰衣草扦插成活效果的影响差异较大。综合分析表明,齿叶薰衣草最佳扦插条件为枝条中部+河沙基质+1000 mg/L的IBA处理60 s,甜薰衣草为枝条中部+珍珠岩基质+1000 mg/L的IBA处理30 s,羽叶薰衣草为枝条基部+河沙基质+500 mg/L的IBA处理15 s。本研究表明在南宁地区进行3种薰衣草的扦插育苗是可行的。

| Abstract: | In order to study the asexual reproduction method of lavender in subtropical regions intensively and to verify the feasibility of establishing lavender breeding bases in southern regions, the effects of different substrates, different parts of the branch, different concentration of IBA hormone and different treating time on the cutting of L. dentata, L. heterophylla and L. pinnata were studied in Nanning. It showed that the cutting effects of L. heterophylla was obviously better than that of L. dentata and L. pinnata. Sand and perlite could be used as the cutting substrate. The middle branch was more suitable for cuttings. The effects of IBA concentration and treatment time on different lavender varieties were different. Integrated analysis implied that the optimum cutting conditions for L. heterophylla, L. dentata and L. pinnata were as follows respectively: middle cuttings + sand + 1000 mg/L IBA 60 s, middle cuttings + perlite +1000 mg/L IBA 30 s, base cuttings + sand + 500 mg/L IBA 15 s. The experiment indicated that raising lavender seedlings of the three varieties was feasible in Nanning. |
