Resumen	Leaf Area Index (LAI) is a dimensionless quantity that measures the total one-sided area of leaves per unit ground area covered by a canopy. It quantifies canopy density and structure: LAI = 0 for bare soil, LAI = 1 for a thin crop, LAI = 3-6 for dense cereal or grass canopies, and LAI > 8 for dense forest. LAI is a key variable in crop growth models, evapotranspiration estimation, and remote sensing because it directly controls light interception, photosynthesis, and water loss from vegetation.	Root Architecture Analysis is a quantitative method in agronomy and plant science that characterises the spatial configuration, branching pattern, and geometric properties of a plant's root system. By measuring parameters such as total root length, lateral root density, root angle, and root tip number, researchers link below-ground structural traits to nutrient and water acquisition efficiency, soil penetration capacity, and ultimately to crop productivity and stress tolerance.
