纽荷尔脐橙果实生长规律Logistic模型探究

摘要

Newhall navel orange was treated with different growth regulators during its flowering phase, and then the growth dynamics of its fruit volume were simulated by using Logistic model. The results showed that the correlation coefficients of the simulative models in various treatments all reached the extremely significant level. The fruit volume growth of Newhall navel orange was divided into 3 phases: young fruit period, fruit intumescence period and fruit maturation period according to the two characteristic points of the simulated Logistic curve.%在纽荷尔脐橙花期用不同生长调节剂进行处理,然后采用Logistic模型拟合了其果实体积生长动态.结果表明:各个处理的拟合模型的相关系数均达到了极显著水平；根据所拟合的Logistic曲线的两个特征点,将纽荷尔脐橙果实体积生长划分为3个阶段:幼果期、果实膨大期、果实成熟期.
