摘要摘要：运用随机区组排列，以红叶石楠为材料，采取 3 种激素和 5 种激素浓度进行浸泡处理，观察扦插后生根情况。结果表明，生根效果表现为吲哚丁酸>ABT生根粉>吲哚已酸；适宜浓度处理可以明显提高生根效率；200 mg/L 的吲哚丁酸处理插条生根效果最好。关键词：红叶石楠；扦插；吲哚乙酸；吲哚丁酸；ABT 生根粉IAbstractUsing randomized block arrangement and Photinia rubra as material, three hormones and five hormone concentrations were soaked to observe rooting after cutting. The results showed that the effect of rooting was indolebutyric acid > ABT Rooting Powder > indolecaproic acid; suitable concentration treatment could significantly improve rooting efficiency; 200 mg/L indolebutyric acid treatment had the best rooting effect.Key words: Photinia rubra; Cutting; Indole acetic acid; Indole butyric acid; ABT rooting powder目录第 1 章 背景与意义............................................3第 2 章 引言..................................................3第 3 章 材料与方法............................................43.1 试验材料..............................................43.2 试验方法..............................................4第 4 章 结果与分析............................................54.1 不同激素对红叶石楠扦插后 25D 后愈伤组织形成状况.........54.2 不同激素对扦插苗浸泡两个小时后生根条数的影响..........54.3 不同激素对扦插苗生根长度影响..........................64.4 不同激素对扦插苗生根率的影响..........................64.5 不同激素对扦插苗成活率的影响..........................74.6 不同体积分数 NAA 插前处理后红叶石楠生根情况.............84.7 不同体积分数 IBA 插前处理后红叶石楠生根情况.............84.8 不同体积分数 IAA 插前处理后红叶石楠生根情况.............94.9 不同体积分数 NAA+IBA 插前处理后红叶石楠生根情况........104.10 不同体积分数 NAA+IAA 插前处理后红叶石楠生根情况.......114.11 不同体积分数 IBA+IAA 插前处理后红叶石楠生根情况.......114.12 插前喷洒叶面扦插生根时间...
