摘　　要：应用Origin软件对南丰蜜橘果实生长动态进行Logistic曲线拟合,并对拟合结果进行分析和验证。结果表明,南丰蜜橘单果重与果实发育时间可以用Logistic曲线方程拟合,南丰蜜橘各品(株)系果实单果重的Lo-gistic曲线方程相关系数大于0.95,并呈显著水平;南丰蜜橘小果系SS-28和小果系97-1的Logistic曲线方程的预测值与实测值的相关系数分别为0.9033和0.9444,并呈显著水平,标准误差分别为4.5063和3.2684。Logistic曲线能较好地反映南丰蜜橘果实的生长动态。This paper deals with fitting Logistic curve of the growth dynamic of Nanfeng tangerine with Origin software. And the results were analysed. The regression between fruit mass and development days could be simulated by Logistic equation. All the correlation coefficients of the Logistic equation were higher than 0.95. Significant levels of correlation were showed. The correlation coefficient between predicted values from Logistic equations and measured values of Nanfeng tangerine small-fruit selections SS-28 and 97-1 were 0.903 3 and 0.944 4 respectively and the values of standard errors were 4.500 63 and 3.268 4 respectively. The correlation of the predicted values and the measured values was significant. The Logistic curve reflected the growth dynamic of Nanfeng tangerine fruit commendably.
