Phenotypic variations of Andira fraxinifolia Benth. (Fabaceae) from two Restinga sandbank formations

ABSTRACT

The study analyzed the variability of morphological trait variability of Andira fraxinifolia from two different Restinga formations. The study was conducted at Acaraí State Park, São Francisco do Sul, Santa Catarina, Brazil, in areas of shrub-tree Restinga and Forest transition. Five individuals were selected on each area in order to characterize their height, trunk diameter at breast height, leaf morphological traits, and stem anatomical traits. Andira fraxinifolia presented phenotypic variations between the studied areas; leaf dimensions and the plant size being the most significant variations. The structural adjustments of these traits can be adaptive, allowing the plant survival in areas with distinct environmental conditions.
