The objective of this study was to analyze leaf area data for four cotton cultivars estimated using the Petiole and LeafArea software, with leaf area calculated as the product of leaf length, leaf width, and a correction factor, and the LI-COR device method used as the standard for validation. The validation of the data estimated by the Petiole software and LeafArea, and the method by which leaf length and width correlate, was performed using statistical indices to evaluate precision and accuracy. The petiole showed the best performance in estimating leaf area for the cultivars TMG44B2RF, IMA5801B2RF, and FM985GLTP. The methodology using leaf dimension measurements and a correction factor is more effective for estimating the leaf area of cultivar BASF – FM 944GL. Among all the evaluated methods, the LeafArea method had the lowest effect on the leaf area of the cotton cultivars. The methodologies evaluated provide precise and accurate estimates of leaf area for the different cotton cultivars, with results that vary across cultivars.
Keywords: leaf morphometry; digital photography; Gossypium hirsutum L.; image processing.
