The result showed that treatment of 500 mg·L -1 IBA or 500 mg·L -1ABT is better than other treatments. It also showed that the biennial cuttings treated with 500 mg·L -1IBA are more active than the annual cuttings with same treatment, and its rooting rate reaches to 100%. But the rooting rate of the annual cuttings is higher than that of the biennial cuttings treated with 500 mg·L -1 ABT, the rooting rate reaches to 90%.展开更多
选用3个杜鹃花品种Rhododendron‘Orchid Lights’,R.‘Millennium’,R.‘Pink and Sweet’的嫩枝为插穗,以V(泥炭)∶V(珍珠岩)∶V(3Lmix)=2∶2∶1为扦插基质,以不同施用方法和不同质量浓度的吲哚丁酸钾盐(K-IBA)处理插穗,在全光照自动...选用3个杜鹃花品种Rhododendron‘Orchid Lights’,R.‘Millennium’,R.‘Pink and Sweet’的嫩枝为插穗,以V(泥炭)∶V(珍珠岩)∶V(3Lmix)=2∶2∶1为扦插基质,以不同施用方法和不同质量浓度的吲哚丁酸钾盐(K-IBA)处理插穗,在全光照自动间歇喷雾下进行嫩枝扦插试验。结果表明:不同品种间扦插生根率、平均根长和根体积差异均达到极显著水平;3个杜鹃花品种的生根效果以品种R.‘Millennium’最好,R.‘Pink and Sweet’最差,说明品种效应明显。低质量浓度的液态K-IBA对3个品种的生根有明显的促进作用,液态K-IBA质量浓度为1000 mg·L-1时对R.‘Orchid Lights’和R.‘Pink and Sweet’品种的生根效果最好,液态K-IBA质量浓度为3000mg·L-1时对品种R.‘Millennium’的处理效果较好。2种不同IBA(K-IBA和Hormodin)的7种处理方法对3个品种插穗的生根率、平均根长和根的体积具有显著性影响。展开更多
