【摘要】 对具有较强适应性和抗性的5种忍冬,采用嫩枝扦插法,以不同浓度的IBA作为生长调节剂对插穗进行处理,分析药剂浓度对插穗生根率和植株生长状况的影响。结果表明:这5种忍冬的扦插生根率为14.4%~87.6%,蓝叶忍冬扦插平均生根率最高,达到了87.6%。低浓度药剂100 ppm、200 ppm利于忍冬插穗的生根和株高的生长,高浓度500 ppm药剂能刺激忍冬根系分根数的增加,药剂的浓度对忍冬根系长度的生长影响不大。更多还原

【Abstract】 The influences of agent concentration on the rooting rate of cuttings and growth status of 5 kinds of Lonicera L. with higher adaptability and resistance have been analyzed after treating the cuttings by use of IBA with different concentrations. The results show that the rooting rate of 5 kinds of Lonicera L. is 14. 4%- 87. 6%,and the rooting rate of Lonicera korolkowii is the highest,reaching up to 87. 6%. The low concentration of 100 ppm and 200 ppm is suitable for the rooting and growth of cuttings,the high concentration of 500 ppm can promote the increase of root tips. There is no obvious influence of the agent concentration on the growth of root length.更多还原
