Fig. 5. Biomass allocation in seedlings at 90 days after seed sowing. Error bars represent ± 1 standard error of the mean. The symbol * represents significant difference at p ≤ 0.05 and NS represents no difference between two species (independent sample t-test). RMF: root mass fraction; SMF: shoot mass fraction; LMF: leaf mass fraction; RSR: root-to-shoot ratio. S. catechu: Senegalia catechu; L. leucocephala: Leucaena leucocephala.
