| 摘 要： | 以苦苣苔品种Primulina dryas‘Hisako’和Primulina‘Blue Mood’为试材,采用正交实验设计,分析不同因素、不同基质组分对扦插成活率、子株数、子株叶数的影响,并筛选出最优组合。探讨影响报春苣苔属扦插成活的因素,为报春苣苔属的扦插繁殖技术提供参考依据。结果表明:3种不同因素对Primulina dryas‘Hisako’成活率的影响大小为浓度>基质>叶片部位,对子株数的影响大小为叶片部位>浓度>基质,对子株叶数的影响大小为基质>叶片部位>浓度,最优组合为IBA+NAA等量混合浓度100 mg·L^-1+泥炭:珍珠岩:蛭石的体积比2∶1∶1+叶片下部。4种基质组分对P.‘Blue Mood’成活率的影响大小为泥炭>稻壳炭>蛭石>珍珠岩,对子株数的影响大小为珍珠岩>泥炭>蛭石>稻壳炭,对子株叶数的影响大小为泥炭>稻壳炭>珍珠岩>蛭石,扦插基质最优组合为泥炭、珍珠岩、蛭石、稻壳炭的体积比6∶2∶2∶1。

| Abstract: | In order to provide reference for the cutting propagation technology of Primulia,the factors influencing the cutting survival of Primulia were discussed.With Primulina Dryas‘Hisako’and Primulina‘Blue Mood’as materials,orthogonal experiment design was used to study.Three factors and three levels test were carried out on P.Dryas‘Hisako’and four factors and three levels test were carried out on P.‘Blue Mood’.The effects of different factors and matrix components on the survival rate,number of new plants and leaves of new plants were analyzed,and the best combination was selected.The results showed that the influence of three different factors on the survival rate of P.Dryas‘Hisako’was concentration>substrate>leaf position,the influence on the number of new plant was leaf position>concentration>substrate,the influence on the number of new plant′s leaves was substrate>leaf position>concentration,the optimal combination was IBA+NAA equal mixed concentration of 100 mg·L^-1+peat∶perlite∶vermiculite volume ratio of 2∶1∶1+lower part of leaf.The effect of the four substrate components on the survival rate of P.‘Blue Mood’was peat>rice husk charcoal>vermiculite>perlite,the effect on the number of new plant was perlite>peat>vermiculite>rice husk charcoal,the effect on the number of leaves were peat>rice husk charcoal>perlite>vermiculite,the optimal combination of cutting substrate was peat,perlite,vermiculite,rice husk charcoal volume ratio of 6∶2∶2∶1. |
