Abstract
Quality of cut flowers was influenced profoundly by cutting in chrysanthemum(Dendranthema morifolium cv.'Jingba').According to growth data of cuttings with different quality level,we established plant growth simulation equations.The first grade cuttings required 15.2 days to arrive quick growth phase after plantation,and growth velocity was 1.55 cm per day.The simulation equations was: Y=91.012/[1+exp(2.627-0.085t)],r2=0.996.The time for the second grade cuttings was 16 days,and growth velocity was 1.51cm per day.The simulation equation was: Y=90.037/[1+exp(2.655-0.082t)],r2=0.998,the time for the third grade cuttings was 15.8 days,and the growth speed was 1.39 cm per day.The simulation equation was: Y=85.106/[1+exp(2.618-0.081t)],r2=0.996,linear relationship between height and fresh weight: Y=0.473x+56.27,r=0.89,linear relationship between height and time to florescence: Y=-1.19x+202.7,r=0.976,and the linear relationship between height and stemdiameter: Y=180.85x-37.71,r=0.919.Compared with the uniformity of height,fresh weight and the time to florescence,the cuttings after filtration performed much well than control.The model developed in this study can predict plant growth properties from standard cuttings and can be used for decision making to optimize uniformity-control for standard cut chrysanthemum production in greenhouse.
