Daftar Isi:
- Shorea macrophylla and S. pinanga are species that can produce illipe nuts. Both species can be found at PT Sari Bumi Kusuma�s natural stands area. According to IUCN Redlist criterias, both species can be categorized as vulnerable species. Therefore, genetic diversity and mating system studies are needed to find out genetic resources conservation strategy and silvicultural action. This study has been done using isozyme marker. Electrophoresis ran using leaves extract from seedlings. Samples were seedlings that grown from fruits collected during exploration a year before. Results showed that both species have high expected heterozygosity, but there were several rare alleles that can be extinct in the future. Both species tend to outcross, with tm = 0.971 ± 0.023
