生根剂对两种风箱果品种扦插生根质量的影响

Effects of Rooting Hormones on Cutting Rooting Quality of Physocarpus opulifolius ‘ Luteus ’and‘Summer Wine

为促进彩叶风箱果扩繁及推广,分别以金叶风箱果(Physocarpus opulifolius‘Luteus’)和紫叶风箱果(P.opulifolius‘Summer Wine’)的嫩枝穗条为试材,在全光喷雾条件下开展秋季扦插试验,探索不同生根剂处理对其扦插生根的作用。结果表明:2个品种中,金叶风箱果生根能力强于紫叶风箱果,生根剂可以促进插穗节间生根,提高生根质量;金叶及紫叶风箱果经生根剂处理后生根率最高分别可达97.8%和94.4%,且不定根数目及平均根长等指标均比较理想。

For successful propagation and popularization of Physocarpus opulifolius ＇ Luteus＂ and ＇ Summer Wine＇, the effects of different hormone treatments on softwood cutting of the two attractive varieties were studied in the condition of all-optical spray in autumn. The result showed that in the two species, ＇ Luteus＇ had a greater rooting ability than ＇ Summer Wine＇. Hormones could promote rooting and improve the rooting quality,and the greatest rooting percentage of ＇Luteus＇ and ＇Summer Wine＇ were 97.8% and 94.4% ,respectively. Number of adventitious roots, the average root length and other indicators were comparative ideal.
