    Anatomical investigation of root, stem and branch wood in 10-year-old Inga laurina in the context of anatomical adaptation to hydraulic and mechanical stresses

    Wood varies between species, from pith to bark, roots to crown within the same plant to ensure hydraulic safety and efficiency. Inga laurina (Sw.) Willd. is investigated herewith for the structural heterogeneity of the wood, since this species thrives well in all major forests of Brazil. I. laurina stem wood possessed narrow vessels; thick walled fibres; wider, taller and higher frequency of rays, features that provide hydraulic and mechanical adjustments. Thick walled fibres and less parenchyma as compared to root provide enough strength to stem to support the large crown. Higher proportion of parenchyma cells in roots results in a high storage capacity for starch, which is important for the shoot recovery after fire damage, common in the Cerrado.
