Leaf angle distribution modelled by Beta function. Analysis of two reconstructed field-grown wheat canopies that shows the reconstructed leaf angle distributions θ (black bars) and calculated Beta functions with \(f\left(t\right)=\frac{1}{B\left(\mu \text{,}\nu \right)}*{\left(1-t\right)}^{\mu -1}*{t}^{\nu -1}\) (a) red; (b) orange), both displaying a high concordance (CCC > 0.5) between distribution and fit; a) CCC = 0.8, and b) CCC = 0.56 (Variety: Matthus; sowing density: \(250 \frac{seeds}{{m}^{2}})\)
