摘　　要：为了提高糯玉米栽培技术和品种选育效果,应用Origin软件对糯玉米品种‘垦粘1号’,‘吉糯3号’和‘京科糯2000’的果穗的生长动态进行Logistic曲线拟合,并对拟合结果进行分析。结果表明,各糯玉米品种的单穗重与果穗发育时间可用Logistic曲线方程拟合且各糯玉米品种单穗重的Logistic曲线方程相关系数均大于0.99,达极显著水平;各测量值与曲线拟合值间的残差相对较小,且残差随时间变化具周期性;通过所求曲线参数求得的糯玉米单穗重发育的关键点和关键时期,能更好的说明糯玉米单穗重的发育过程,实验结果表明Logistic曲线能较好地反映糯玉米单穗重的生长动态。In order to increase the technology of cultivation and the efficiency of breeding of waxy corn, this study dealt with fitting Logistic curve of the growth dynamic of single ear of waxy corn varieties ＇ Kennianl＇, ＇Jnuo3＇, ＇Jingkenuo2000＇ with Origin software. The results showed that, the regression between single ear mass of the test varieties and development days could be simulated by Logistic equation. All the correlation coefficients of the Logistic equation were higher than 0.99 significant levels of correlation were showed. The residual errors between measure values and values of fitting curve were relative small and had periodicity. The developmental process could be explained better through the key points and key time intervals were figured out by parameter of fitting curve. The Logistic curve reflected the growth dynamic of waxy corn single ear mass relative correctly were showed by this experiment.
