Research on the Simulation Model of Above-Ground Organs Morphogenesis of Flue-Cured Tobacco

.In order to create the simulation model of Above-ground Organs Morphogenesis of Flue-cured Tobacco, the dynamic model of organ morphology in different growing step of tobacco was built with potting experimental methods with which the biomass of tobacco organ in different growth period can be systematically determined. As simulation of organ morphology of tobacco measured in 2007 shows that the correlation coefficient between the simulated value and the measured value of above-ground organ of tobacco in different growth cycle is 0.735 to 0.9997 at significant level which proved that the dynamic of above-ground organ morphogenesis of tobacco can be predicted well by the model. The regulation of growth of tobacco morphology can be reflected well by the model of above-ground organ morphogenesis; furthermore, the model can also be a theoretical basis for virtual growth of tobacco.
