摘　　要：为构建辣椒形态结构模型,实现植株可视化,在田间试验的基础上,综合分析了温度对辣椒叶片形态发生的影响,量化了温度与叶片形态建成的关系,构建了基于有效积温(GDD)、以Logistic方程为基础的辣椒叶片长度、宽度及数量形态发生的动态模型,并利用独立的试验资料对模型进行检验。结果表明:辣椒叶片长度、宽度及数量的模拟值与观察值之间的均方根差分别为1.328cm、0.384cm和6.615片,辣椒叶片形态发生的观测值与模拟值具有良好的吻合度,模型具有较好的准确性和预测性。In order to construct the morphology model and realize the visualization of the chili pepper plant,the effect of temperature on the development of chili pepper leaves were quantified,the relationship of temperature and the morphogenesis of leaves were quantified,and physiological dynamic simulation model on length,width and number of leaves which based on growing degree days（GDD） and Logistic equation was constructed,based on the field experiments in 2008 and 2009.Independent experimental data sets were used to validate the models.The results showed that the root mean square error（RMSE） between simulated value and observed value of the length,width and number of leaves were 1.328 cm,0.384 cm,and 6.615 pieces of leaves,respectively.The simulated value and observed value had high goodness of fit,which indicated that the model was accurate and predictive.
