ANATOMICAL COMPARISON OF POPULAR BRACATINGA (Mimosa scabrella Bentham) VARIETIES OF WOOD

ABSTRACT

The main objective of this research was to compare anatomical wood characteristics of the popular varieties of Mimosa scabrella Bentham known as bracatinga-branca, bracatinga-vermelha and bracatinga- argentina. The material used in this work was collected from 6 to 7 years old trees of the popular varieties from areas located in Colombo municipality, State of Paraná, owned by Embrapa Florestas. Botanic for anatomical characterization of wood material was identified and described. Results did not show differences of anatomical characteristics between the bracatinga-branca and bracatinga-vermelha. The bracatinga- branca and bracatinga-vermelha showed statistically differences in relation to bracatinga-argentina to average values in pores tangential diameter, pores quantity per square mm, vessel elements individual length, axial parenchyma cells diameter, unisseriate and multisseriate rays width. In conclusion, the observations contribute to a better understanding of the differences showed by the popular varieties.
