[Objective]The aim to study the effects of different hormone ratios on the cutting and propagation ability of Narcissus tazetta.[Method]The bulbs of three N.tazetta varieties,Yulinglong,Golden Sun and Autumn Pearl were processed with different concentrations of 6-BA and KT,respectively,to calculate the propagation of different N.tazetta.[Result]The cutting ability of different varieties of N.tazetta was significantly different,and the ability of Yulinglong to produce small bulbs after cutting was stronger than Golden Sun.The use of exogenous hormones 6-BA and KT could effectively improve the propagation coefficient of the three N.tazetta varieties bulbs cut,among which 25 mg/L 6-BA+10 mg/L KT treatment Yulinglong was better,and the multiplication of small bulbs was 1.98 times that of the control.50 mg/L 6-BA+10 mg/L KT showed higher reproductive coefficients of Golden Sun and Autumn Pearl bulbs,which were 2.00 times and 2.21 times of the control,respectively.[Conclusion]Hormones would improve the reproduction efficiency of N.tazetta and speed up the popularization and application of N.tazetta.
