果实大小预测可分为定量预测和定性预测两类。笔者从果实大小预测的依据、时期和方式三方面论述了果实大小定量预测的研究现状，把果实大小的定量预测归纳为表格法和预测函数法两种。指出：果实大小的定量预测应依据果实自身的生长状况；从群体和定量的角度来预测果实大小是发展方向 Fruit size prediction can be divided into quantitative prediction and qualitative prediction of two categories. The author discusses the research status of quantitative prediction of fruit size from three aspects: the basis, period and mode of fruit size prediction. The quantitative prediction of fruit size is summarized into two kinds: form method and predictive function method. It is pointed out that the quantitative prediction of the fruit size should be based on the fruit’s own growth status. It is the development direction to predict the fruit size from the perspective of population and quantitative
