- 摘要:
- 为了研究不同因素对4种报春苣苔属植物叶插效果的影响,并筛选出适合不同报春苣苔的最佳叶插处理条件。以‘紫氛’报春苣苔(Primulina‘Purple Fumes’)、冬花报春苣苔(P. hiemalis)、寿城报春苣苔(P.shouchengensis)和长柱报春苣苔(P. longistyla)叶片为材料,进行不同叶片部位以及不同IBA浓度的扦插试验。结果表明,4种报春苣苔最佳叶插部位均为上部叶片,较下部叶片更易产生子株。不同IBA浓度对4种报春苣苔的处理效果不同,‘紫氛’报春苣苔、冬花报春苣苔、寿城苣苔和长柱报春苣苔的上部叶片切口在浓度分别为500,300,100和500 mg·L-1的IBA溶液中浸泡15 s,可以达到最佳的扦插处理效果。
- Abstract:
- In order to study the effects of different factors on leaf cuttings of four Primulina species, the optimum conditions of leaf cuttings for different species were screened. Cutting experiments of P. ‘Purple Fumes’, P.hiemalis, P.shouchengensis and P.longistyla were carried out on different leaf positions and IBA concentrations.The results showed that the best leaf position for cuttings of four Primulina species was the upper leaf, which was easier to produce the new plant than the lower leaf. The treatment effects of different IBA concentrations on the four Primulina species were different. The best cutting effect can be achieved by immersing the incisions of the upper leaves of P. ‘Purple Fumes’, P.hiemalis, P.shouchengensis and P.longistyla in IBA solution with concentrations of 500, 300, 100 and 500 mg·L-1 for 15 seconds.
