- 摘要:
- 以方枝野海棠扦插枝条为试材，采用5%萘乙酸钾盐水剂为根动力药剂，研究了不同浓度根动力剂以及不同浸泡时间对方枝野海棠枝条扦插繁育中根系生长发育的影响。结果表明：随根动力剂浓度的增加和浸泡时间的延长，方枝野海棠插穗扦插的成活率均呈现出先增加后减小的趋势；同时，其生根率、根长以及发根数亦表现为先增加后减小的趋势。其最佳处理浓度为萘乙酸水剂60倍稀释液，最佳浸泡时间为10 min，可使插穗生根率达98.26%，平均根长达11.49 cm。
- Abstract:
- Taking the cutting branches of Bredia quadrangularis Cogn.as experimental material,using 5% 1naphthylaceticacid K+ solubility liquid (SL) as rooting agent，the effects of different concentrations and immersion time of rooting agents on cutting propagation of Bredia quadrangularisCogn.were studied.The results showed that the effects were strong varied with the change of the concentrations and immersion times，the survival rate of Bredia quadrangularis Cogn. first increased and then declined along with the enhance of the concentrations and immersion times of rooting agent under a certain concentration exposition.The rate of rooting，length of root and number of rooting plants presented the same principle.The optimal concentration was 60 times，the optimal immersion time was 10 min，and they could make the rate of roofing reached 98.26%，the average length of root reached 11.49 cm.
