| Abstract: | The growth at GBH of 8 trees of Tectona grandis L.f., Camptotheca acuminata Decne and Mayodendronigeum Kurz were measured for six years with dendrometers. Mean annual growth at GBH was between 1 5cm and 2 5cm, with the most growth from June to Augast. The annual growth was not significantly correlated with the sum of temperature and sum of rainfall in a year. Growth at GBH of the trees showed similar monthly patterns to that of rainfall and temperature. The mean daily growth was more significantly correlated with the mean daily rainfall than mean temperature. It was found that the response to rainfall and temperature was different among the species. |
