The res- in output of Australia hybrid pine was 3 057 kg/hm2 in whole year and it was higher than that of Slash pine , Caribbean pine and Masson pine by 43.1 % ,59.9% ,82.5% respectively. The resin output of Australia hybrid pine was related to the in- dex of the tree height and its diameter. The study also showed that the resin chemical compositions of Australia hybrid pine , Slash pine , Caribbean pine and Masson pine were very similar. There was no any difference between Australia hybrid pine and Slash pine or between Australia hybrid pine and Caribbean pine in the chemical composition. There was a little differ- ence between Australia hybrid pine and the Masson pine.
