摘　　要：为了优化卡亚(Cnidoscolus aconitifolius)的扦插繁殖技术,以卡亚当年生半木质化嫩枝为试验材料,探究不同生根剂种类和浓度以及不同基质对不同品种卡亚扦插生根的影响。结果表明,将卡亚插条在500 mg/L的IBA溶液中处理2 h后,扦插于基质3(椰棕∶泥炭土=3∶1)中,其生根效果最佳,生根率可达93.15%,平均根数为24.53条,平均根长为32.90 cm。'Chaya'品种有更好的生根效果。To optimize cuttage propagation of Cnidoscolus aconitifolius,taking semi-lignified twigs as materials,effects of different types and concentrations of rooting agents,different substrates on rooting of C.aconitifolius with different varieties were studied.Results showed that rooting rate was 93.15%when cuttings were treated in 500 mg/L IBA solution for 2 h,then implanted in substrate 3(coconut palm∶peat soil=3∶1)with average number of roots 24.53 and average root length 32.90 cm.The variety of'Chaya'had better rooting effect.
