A fractal root model applied for estimating the root biomass and architecture in two tropical legume tree species

Abstract: -A fractal root model with parameter estimation based on pipe model theory was applied for studying root architecture of Erythrina lanceolata and Gliricidia sepium associated with crops in agroforestry. The results were compared with a theoretical volume-filling fractal model on scaling of plant vascular system. Scaling of root diameter at bifurcation followed same parameter values over the whole root system. The parameter values were approximately equal in both species. Length between two bifurcations could n… Show more

“…Further, the lack of dependence of p and q to link diameter of the shoot system and for the first taproot node was also in accordance with the finding by Noordwijk and Purnomosidhi (1995), Soethe et al (2007), and Salas et al (2004).…”

“…The independence of branching parameters (p and q) for all nodes to link diameter reconfirms the self-similar branching pattern of the shoot system (Salas et al 2004;van Noordwijk and Purnomosidhi 1995). For the root system, independence of p values to link diameters was verified only for the first and third nodes (Adjusted R 2 <0.039 and P>0.05), and independence of q values to link diameters was only confirmed for the first and second nodes (Adjusted R 2 =0.028 and P>0.1).…”
