The bulb scales had a higher induction rate of 89.3% to 93.3%, better quality and lower decay rate and the best rooting, in which single-scale reproduction coefficient reached 1.14 to 1.19 when cutting in soil from original environment and peat and pearlite (1:1) as medium under the condition of 25℃ and dark, followed by cutting in peat and sand (2:1) and peat and vermiculite and perlite (1:1:1).
