【 摘 要 】

Pinus merkusii was famous wood and resin producer trees in Indonesia. Previously, pine wood became one of major material for pulp and paper, later along the changes in forestry paradigm, resin product as non wood forest product became more prospective to develop.. Pine as resin-producing tree requires suitable condition for Producing high amount and good quality of resin. The objective of our study was to determine environment factor that influence growth and resin production structure in three Seedling Seed Orchard (SSO) Perum Perhutani, those were Baturaden (Central Java), Cijambu (West Java) and Sempolan (East Java). Data for this research obtained from secondary and primary data in three Perum Perhutani SSO through direct observation and measurement. Result showed that Cijambu SSO has the highest resin production (101.4 g/tree/3days) compared to Baturaden SSO (88.72 g/tree/3days) and Jember SSO (64.4 g/tree/3days), right-skewness resin production distribution structure and wider resin production interval. Pearson correlation test and multiple linear regression for 14 growth characters out of 35 characters were tested. Stem diameter, branching number, bark thickness and crown had moderate correlation with resin yield (r: 0.75). It is concluded that resin production was affected by genetic and enviromental factors. Although resin production was affected by genetic and environmental factor, therefore appropriate stand management (silviculture treatment) must also be implemented because potential genetic expression would be maximized if environmental conditions is well managed.
