Evaluation of Different Sensing Approaches concerning to Nondestructive Estimation of Leaf Area Index ( Lai ) for Winter Wheat

Abstract

Different approaches of non-destructive estimation of the LAI in winter wheat were compared. Plant height had weak relation with the LAI, while estimated biomass showed high logarithmic relationship (R=0.839). NDRE and REIP were logarithmically well related to the LAI (R=0.726 and 0.779 respectively). Saturation effect of NDRE and REIP was less than NDVI… (More)
