摘要
目的 研究多效唑对忍冬生长发育及金银花质量的影响 ,寻找适宜的施用浓度。方法 用紫外分光光度法测定绿原酸。结果 多效唑可抑制花枝的伸长生长 ,增加叶面积 ,增加产量 ,提高花蕾绿原酸含量。低浓度 (10 0 mg· kg- 1 和 2 0 0 mg· kg- 1 )效果较好。结论 低浓度多效唑可用于金银花生产。
Object To study the effect of PP333 on growth and development of Lonicera japonica Thunb. and quality of honeysuckle, so as to find the most suitable using concentration for honeysuckle production.Methods UV spectrophotometry was used to determine the content of chlorogenic acid. Results It showed that PP333 restrained shoot lengthening growth, increased leaf area, raised yield, and increased chlorogenic acid content in honeysuckle. And lower concentration of PP333 (such as 100 mg·kg -1 and 200 mg·kg -1) showed a better effect. Conclusion Low concentration of PP333 was good to honeysuckle production.
