Effects of Seed Bulb Size on the Growth of Bulb in Lilium longiflorum Thunb.

[Objective] The aim of the research was to solve the propagation problem of seed bulb in Lilium longiflorum Thunb.[Method] According to the size and weight of different seed bulbs,20 level treatments were set up to study the effects of seed bulb size on the growth of bulb in L.longiflorum.[Result] The treatment with lily seed bulb size of 50～65 g had obvious increasing effects on bulb fresh weight and dry weight,bulb diameter and bulb quantity.Bulb diameter,fresh weight and dry weight had obvious correlations with the size of lily seed bulb and their regression relational expressions were Y1=40.117 0-22.946 9 X1+3.854 5 X12,Y2=-12.611 2+0.879 5 X2-0.002 059 X22 and Y3=-10.365 6+2.685 1 X3-0.018 91 X32 respectively.[Conclusion] This research provided basis for further study on seed bulb of L.longiflorum.
