华蔓茶藨子压条繁殖技术研究

Research on Asexual Propagation Biology Technique of Ribes fasciculatum var. chinensis

以中国原产野生植物华蔓茶藨子为材料,采用压条进行无性繁殖试验研究,探讨不同压条处理、枝条处理和激素种类及其浓度对生根率和生根质量的影响。结果表明,压条试验中枝条刻伤、激素及不同浓度处理生根率均达到80%以上,刻伤和激素处理的生根率差异不显著,但能明显促进生根数量和根质量,刻伤后施加激素能够显著缩短愈伤组织和不定根出现时间,提高根数和根质量,加速生根进程,其中NAA促进新根萌生的效果略优于IBA,而IBA促进根生长的效果较好;枝条刻伤处理效果比外源激素处理更显著。

The asexual propagation experiments of Chinese wild plant Ribes fasciculatum var.chinensis were carried out by layering,so as to indicate the effects to the rooting rates and quality of roots under different propagation times,hormone and contents.
