Determining the leaf area of fig trees by non-destructive methods

The determination of the leaf area on fig leaves by non-destructive methods, based on the size of the leaves and the correction coefficient, was the objective of the present study. Fig leaves were taken randomly, in different categories and sizes. Leaf samples were herborized to ensure leaf integrity. The leaves were measured to determine length (L), and width (W) dimensions. From the analysis of the scanned images of the leaves, the scanned leaf area (SLA) vas determined. Through the comparative analysis of the measured leaf area (MLA) with SLA, the value of the correction coefficient (CC) was determined. Under CC = 0.58 conditions, the minimum ME error value between MLA and SLA was recorded. The RMSEP = 18.0450 calculated value confirmed the optimal value for the correction coefficient. The regression analysis described the fit between MLA and SLA through a linear equation, under conditions of R2 = 0.950, p<0.001.
