2005
Luciano Denardi | José Newton Cardoso Marchiori
The purpose of this work is the comparison of the wood anatomy of Blepharocalyx salicifolius (H.B. K.) Berg (Myrtaceae) from two provenances in the State of Rio Grande do Sul. There were collected 6samples of wood; three from Serra do Sudeste and the others from Campos de Cima da Serra. The woodanatomical features did not express relevant differences between provenances, with the exception of pithflecks. With respect to the quantitative features, on the other hand, there were found important differences inthe structure of vessels, axial parenchyma, rays and fibres. For the Serra do Sudeste samples, there werefound xeric evidences in the wood: a larger number of small vessels, besides shorter vessel members andfibres, in comparison with those from the Campos de Cima da Serra region. The differences in the woodanatomy may be interpreted as adaptative responses to environmental conditions.
