Allometry of a neotropical palm, Euterpe edulis Mart. Acta Botanica
Alves,Luciana F.; Martins,Fernando R.; Santos,Flavio A.M..
The stem allometry (stem diameter vs. tree height) of a Neotropical palm (Euterpe edulis) found in rain and seasonal forest of Southeastern Brazil was examined. Observed height-diameter relationships along the stem (diameter at ground level, (dgl), and diameter at breast height (dbh) were compared to three theoretical stability mechanical models: elastic similarity, stress similarity and geometric similarity. Slopes of log-transformed height-diameter relationships did not lie near those predicted by any stability mechanical models. Significant differences in stem allometry were found when comparing dgl to dbh, suggesting greater increase in dbh with height. The relationship between stability safety factor (SSF) and palm height showed that both dgl and dbh...
