Abstract
The influence of neighbouring tree species on architectual traits of companion tree species was studied in mixed plantations raised for revegetation of coal mine spoil. The three types of combinations used were legume: legume, legume: non-legume and non-legume: non-legume. The architectural traits analysed were height-diameter relationships and crown mass-trunk mass relationships. The neighbouring species altered the height-diameter relationships in Acacia catechu, Pongamia pinnata, Tectona grandis and Terminalia bellirica. Similarly, the neighbouring species was also found to alter the crown mass-trunk mass relationships in A. catechu, Gmelina arborea, P. pinnata, T. grandis and T. bellirica.
