Non-destructive Leaf Area Measurement using Mathematical Modeling for Paddy Varieties

Abstract

Leaf area is considered an important parameter in fields such as plant phenotyping and plant breeding. In this study, leaf areas of different rice varieties were measured using a leaf area meter. Subsequently, a mathematical model was developed using leaf dimensions to estimate leaf area. Multiple regression analysis was used in the study to examine how leaf area is related to leaf dimensions. The results showed significant differences in leaf areas among different paddy varieties (Efe, Osmancık-97, Hamzadere, and Paşalı). Additionally, leaf dimensions were found to be a strong predictor for estimating leaf area. The equation of leaf area (LA= a + (b x L) + (c x W) + (d x L²) + [e x (L x W)] for paddy varieties tested. The R² values for paddy varieties between 84% - 99%. The mathematical model is an important tool that can be used in plant phenotyping and plant breeding, and can be further utilized in future research in these fields.
