Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method

Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in post-harvest. The leaf area measurement fundamental plants because leaves are directly related several processes such as transpiration, radiation interception CO2 fixation that enable plant grow. objective work was determine an allometric equation for estimating lisianthus from linear dimensions. 200 were collected length (L), width (W), product between (LW) real (LA) measured. criteria determining best model highest determination coefficient (R2), Willmott's concordance index (d), lowest Akaike information criterion (AIC), root mean square error (RMSE) BIAS closest zero. most suitable ŷ = 1.387*LW.
