Conteúdo: |
Calophyllum brasiliense is a hydrophilous tree species widely distributed in Brazil. It often dominates tropical swamp forests and shows morphophysiological responses to flooding and sensitivity to water deficits. To investigate the edaphic influence on the xylem structure of this species, wood samples were obtained from adult C. brasiliense trees in two soil types, Podzol and Histosol, both covered by lowland Atlantic Forest, in a coastal plain in southern Brazil. The sandy texture of Podzol and its microrelief often lead to more mesic conditions compared to Histosol, which is an organic and hydromorphic soil. Permanent slides with histological sections and dissociated material were prepared for qualitative and quantitative anatomical analysis. Principal component analysis and mean comparison tests were performed to assess variations in anatomical traits between soil conditions. Vessel density and fiber length were higher in trees from Podzol compared to Histosol, while the width of the rays was greater in Histosol. Additionally, the cross-sectional area and mean lumen diameter of vasicentric tracheids were larger in populations from Histosol than in Podzol. Furthermore, Vulnerability and Mesomorphy indices showed higher values in Histosol compared to Podzol. While the response associated with vessel occurred in density (higher in Podzol), the response in tracheid is reflected in cell diameter (higher in the soil with more water: Histosol). This publication is likely the first to demonstrate intraspecific variation of vasicentric tracheids in a hydrophilous species. The anatomical structure and functional implications of the observed variations are discussed regarding the efficiency and safety of the conductive system, considering the ecology of the species and the characteristics of the sampled soils.
