摘　　要：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.
