Abstract:
In Maluku and Fiji islands, forest trees are an important vegetation to protect environment quality and provide economical value for community as well as state. In sustainable tree nursery, using Plant Growth Promoting Rhizobacteria(PGPR) to enhance plant growth is recommended. The objective of this assessment was to provide information concerning the diversity and similarity of native forest tree species based on secondary data grown in both tropical Melanesian regions and the possibility to apply PGPR in its seed nursery. The result demonstrated that at least 15 trees genus among them five tree species are naturally grown in both region but the main utilization of those trees in both regions is differed. Tree similarity provides evidence on the same natural factors affecting the process of vegetation establishment in Maluku and Fiji. Timber production in Fiji is more extensive than the one in Maluku, but seed nursery in both regions has not yet applied PGPR as bio fertilizer and bio stimulant. Researchers elsewhere have been studying the presence on PGPR in 10 of 15 genus that also grown in Maluku and Fiji. The future use of PGPR is very promising since naturally indigenous PGPR has been colonizing those tree roots. Further collaborative research is needed to develop certain bio fertilizer for native tree nursery in Maluku and Fiji.
