针对QY、PRI、NDVI、水势分别从不同的方面反映玉米的生理状况，以甜糯二号玉米作为材料，通过田间试验测量玉米昼夜4个参数值，研究了QY、PRI、NDVI、水势4个参数的昼夜变化，并且分析它们之间的相关性。结果表明，QY、水势、PRI三者具有很强的相关性，并且能建立回归模型表示它们之间的联系。

Because QY, PRI, NDVI and water potential can respectively reflect the physiological state of corn from different aspects, the diurnal variations in these 4 parameters of corn variety Tiannuo No.2 at heading stage were studied through field trials, and the correlations among them were analyzed.The results indicated that there were significant correlations among QY, water poten-tial and PRI, which could be expressed by building regressive models.
