有效授粉期（EPP）的概念是由威廉姆斯[J. Hort.Sci. 40（1965）31]来评估花的感受性。它被定义为授粉有效产生果实的天数，由胚珠的寿命减去授粉和受精之间的时间差决定。自这一概念首次提出以来，已经过去了30多年，在此期间，已经进行了大量的实验来研究不同物种和品种以及不同环境条件下的EPP。结果表明，EPP对果树的产量起着明显的控制作用，因此，它是一个有用的参数来解剖和定位限制坐果的因素。本文综述了温带果树EPP的研究进展。由于EPP是由三个主要过程-柱头可授性，花粉管动力学和胚珠发育-他们每个人所扮演的角色进行检查。最后，一些因素的影响-温度，花的质量和化学处理-影响这些参数进行评估。
The effective pollination period (EPP) concept, was developed by Williams [J. Hort. Sci. 40 (1965) 31] to asses flower receptivity. It is defined as the number of days during which pollination is effective in producing a fruit and is determined by the longevity of the ovules minus the time lag between pollination and fertilisation. Over 30 years have elapsed since this concept was first introduced and, during this time, a good number of experiments have been carried out to study the EPP in different species and cultivars and under different environmental conditions. The results obtained indicate that the EPP plays a clear role controlling cropping in fruit trees and, consequently, it is a useful parameter to dissect and locate the factors limiting fruit set. In this paper, the information built up around the EPP is reviewed in temperate fruit trees. Since EPP is conditioned by three main processes — stigmatic receptivity, pollen tube kinetics and ovule development — the role played by each of them is examined. Finally, the influence of a number of factors — temperature, flower quality and chemical treatments — that affect those parameters is evaluated.
