摘要
用不同浓度吲哚丁酸(IBA)处理除虫菊分蘖苗后,对其后期生长有着不同程度的影响,除3125 mg/L浓度以外,用吲哚丁酸处理除虫菊后,其成活率、根冠比、须根数、分蘖数、干重、鲜重、叶片厚度、叶绿素含量各指标与对照相比均有明显提高,其中以625 mg/L处理效果最好,其叶片厚度、成活率根冠比、须根数、分蘖数、干重、鲜重、叶片厚度与对照相比均达到极显著水平,同时叶绿素a、叶绿素b含量也达到了显著水平。并根据各处理指标的分析结果,拟合回归方程,预测理论最佳处理浓度,为吲哚丁酸(IBA)对除虫菊分株繁殖的应用,提供一定的理论指导依据。
After taking off and using the IBA of the different concentration to treated pyrethrum offshoot, as to it＇s expect to have the influence of its different degree to pyrethrums growth. After using the IBA processing pyrethrum, the survival rate, root/shoot ratio,the number of whiskers root, the number of tillers, stem heavy, fresh heavy, a leaf thickness, the chlorophyll content etc. each index sign all showed the significant increasing, excepted by 3 125 mg/L handle outside, among them the 625 mg/L is best, the leaf thickness and the survival rate compared to controls reach the most significant level, the root/shoot ratio and the chlorophyll becomes to the level of significance,and other each index sign compared to control also had the obvious increase. And according to each dealing with the analysis result of the index, fit and return to the equation, predict that deals with IBA and application breeding to the Dalmatian pyrethrum offers theory to guide the basis.
