不同生长调节剂对三角梅水培生根的影响

Effect of Different Plant Growth Regulators on Rooting of Bougainvillea spectabilis in Water Culture

为高效率大面积生产繁殖三角梅种苗满足市场需求提供技术依据,采用水培试验法,探究生根液及2种植物生长调节剂对三角梅扦插生根的影响。结果表明:生根液和植物生长调节剂对三角梅水培插条的生根时间、生根根数、生根根长、萌发新芽枝条数有不同程度的影响,其中IBA 200mg/L处理的促根效果最好。

The effect of ABT,NAA and IBA on rooting of Bougainvillea spectabilis cuttings in water culture was studied to provide a reference for high efficiency large-area production and propagation of B.spectabilis seedlings to meet its market demand.Result:ABT,NAA and IBA have different effects on rooting time,rooting number,root length and new germinated branches of B.spectabilis cuttings.200 mg/L IBA has the best effect on root-induction of B.spectabilis cuttings.
