| 摘 要： | 通过对影响生根的生长素种类和浓度等因素的研究，确定了柱型苹果鲁加6号最佳生根生长素组合，即：1/2MS＋0.3 mg·L^-1IAA＋1.0 mg·L^-1IBA。试验结果表明，鲁加6号生根率可达100%，平均生根数达到8.9根。IAA和IBA组合处理的组培苗生根质量明显比单一生长素处理好。正交试验结果表明，影响鲁加6号生根的主次因素顺序为IAA〉IBA〉NAA。

| Abstract: | The hormone such as type and concentration on rooting has been studied in columnar apple ＂Lujia No. 6＂. The optimal rooting medium of columnar apple ＂Lujia No. 6＂ has been chosen,that was 1/2MS＋0. 3 mg · L-1IAA ＋1.0 mg · L^-1IBA. The results indicated the treatment with combination of IAA and IBA was the best. In the best root system of ＂Lujia No. 6＂,rooting rate was up to 100% and average rooting per plantlet reached 8. 9. The plantlet in vitro treated by IAA and IBA has more root hairs than the one by IBA or NAA. Orthogonal test indicated that their important order was IAA〉 IBA〉NAA. |
