- 摘要:
- 为了促进紫叶风箱果在北京地区的繁殖，研究了激素种类、处理浓度和时间及插穗直径等因素对紫叶风箱果硬枝插条生根的影响，从中找到最佳的扦插繁殖方案。结果表明：用300 mg?L-1ABT处理1 h效果最好，插条的生根率可达80%，平均根数为30.8条，平均根长2.9 cm；ABT 处理的插穗生根效果比IBA好；插条直径0.8 cm以上有利于生根。
- Abstract:
- In order to promote the breeding of Physocarpus opulifolius’ Diabolo’in Beijing area，the etfect of different growth regulators,concentrations,treatment time and cutting diameter on cutting propagation of Physocarpus opulifolius’ Diabolo’ was studied.The results showed that rooting was maximized (80%) for cutting treated with 300 mg?L-1?ABT for 1 h,the average root number was 30.8,the average root length was 2.9 cm.The cuttings treated by ABT had more roots and higher rooting rate than those treated by IBA.The optimal hardwood cuttings’ diameter should be greater than 0.8 cm.
