Effects of intra-specific tree competition on dendrometric parameters of Peltophorum dubium

The purpose of this research was to assess the performance of dendrometric parameters of 'Peltophorum dubium' in several trees competition and stand age. The experiment was carried out in Brazil from 2009 to 2013. The experimental evaluations were done on variables such as cylindrical volume (CV), crown diameter (CD), diameter at beast height (DBH1.3 m), crown area (CA) and total height of tree (THT). The experiment was performed in a Nelder wheel competition, which is used in forestry research to test tree competition in a single plot. The interaction between the treatments (tree competition and stand age) was statistically significant (p
