4种生根促进剂对大叶女贞扦插生根的影响
|
摘要
为筛选大叶女贞最佳生根促进剂,以大叶女贞优良抗寒单株一年生萌条为试验材料,采用萘乙酸、吲哚丁酸、萘乙酸钠、吲哚丁酸钾在50,100,200 mg·L~(-1)慢浸,和300,500 mg·L~(-1)速蘸进行处理,统计大叶女贞生根率、生根数和最长根长。结果表明:与对照组相比,4种生根促进剂和5个浓度处理均可显著提高大叶女贞生根率;4种生根促进剂仅萘乙酸处理,5个浓度中仅200 mg·L~(-1)浓度处理可显著提高大叶女贞生根数;4种生根促进剂和除500 mg·L~(-1)外的其他4个浓度处理均可显著提高大叶女贞最长根长。运用隶属函数进行综合分析,各处理中以萘乙酸200 mg·L~(-1)对大叶女贞的生根综合效果最好,其次为吲哚丁酸钾200 mg·L~(-1)。
In order to screen the optimum rooting accelerator for Ligustrum lucidum Ait, the cuttings from annual plants with good cold resistance were processed using Naphthalene acid, Indolebutyric acid, Sodium naphthalene-1-acetate, Potassium 4-butanoate at the concentration of 50, 100, 200 mg·L~(-1) for slow-soaking and 300, 500 mg·L~(-1) for quick dipping, and the rooting rate, root number,and longest root length were recorded. The results showed as follows: compared with the control, four different rooting agents and five different concentrations significantly increased the rooting rate, only naphthalene acetic acid in four rooting agents and 200 mg·L~(-1) in five concentrations increased the root numbers significantly, four rooting agents and the remained 4 concentrations except 500 mg·L~(-1) significantly improved the longest root length. Comprehensive analysis by subordinate function, the optimal rooting accelerator was Naphthalene acid, and the optimal concentration was 200 mg·L~(-1), and then was Potassium 4-butanoate under the concentration of200 mg·L~(-1).
