A study on production of resin from pinus merkusii jungh. Et De vriese in the Bosscha observatory area, west Java-Indonesia

Abstract

We investigated the variability in resin production of a pine stand in Bosscha Observatory Bandung (Indonesia) with the aim to exploit this natural resource in a sustainable way. The potential resin productivity of the pine stand in observatory bosscha area has been known. Therefore, it is necessary to investigate the use of methods (quarre and drill method) in pine resin productivity. The tapping method resulted in differences in resin production in 20-25 year-old trees. The production of extracted with the quarre method was 19.34 g treeG1, meanwhile, the drill method resulted in 32.64 g treeG1. The potential annual resin production in bosscha observatory area were 9.29 and 15.640 t yearG1 for quarre and drill method, respectively. The resin production capacity of pine species (P. merkusii Jungh. Et de Vriese) were affected by tree diameter.
