| 中文摘要: |
| 采用正交试验设计研究了扦插温度、扦插基质、激素类别、激素浓度对罗汉果组培苗扦插效果的影响。结果表明：成活因子和长势因子分别为第1、2主成分,2个因子的方差累计贡献率在77%以上；扦插温度、激素类别对扦插苗的影响较大,扦插基质、激素浓度影响次之；扦插效果最佳组合为：扦插温度25 ℃,扦插基质为细河砂,激素浓度为200 mg/L的吲哚丁酸。 |
| 英文摘要: |
| Through orthogonal design, to establish the cutting propagation system of Siraitia grosvenorii. Four factors were tested by orthogonal design, including cutting temperature, cutting matrix, hormone type and hormone concentration. The results show that the survive factor served as the first principal component and the grew factor the second. The accumulative variance contribution of them was more than 77%. Cutting temperature and hormone type had more significant effect than that of cutting matrix and hormone concentration on cutting propagation. The treatment of Siraitia grosvenorii cultured in vitro treated with 200mg/L IBA in bank sand at 25℃ was the optimal combination for survival rate of cutting propagation. |
