description |
Forest degradation in Indonesia led to the extinction of Shorea macrophylla
and Shorea stenoptera as the major source of illipe nut (tengkawang) oil. To protect
those species from being extinct, genetic conservation such in-situ conservation are
necessary. The study was aimed to determine the genetic variation of S. macrophylla
and S. stenoptera in natural forest population and the distribution of genetic
variation in four living levels, i.e. trees, poles, saplings, and seedlings.
Leaf and cambium samples of two Shorea species were collected from
natural forest at Desa Sungai Buaya, Kecamatan Kayan Hilir, Sintang, Kalimantan
Barat by purposive sampling. Genetic variation observed by 3 primers microsatellite
marker, i.e. Shc-2, Shc-7, and Shc-9. Data were analyzed using GenAlex 6.5.
The results showed that proportion of polymorphic locus is 100% of both
species. The observed heterozygosity (Ho) of S. macrophylla are 0,633 (trees), 0,292
(saplings), and 0,333 (seedlings), while expected heterozygosity (He) are 0,560
(trees), 0,353 (saplings), and 0,318 (seedlings). Ho for S. stenoptera are 0,633
(trees), 0,542 (saplings), and 0,422 (seedlings), while He 0,462 (trees), 0,557
(saplings), and 0,541 (seedlings). The genetic variation of S. macrophylla derived
from trees to saplings level was 46,129% and seedlings level was 52,606%, while
genetic variation of S. stenoptera derived from trees to saplings level was 83,624%
and seedlings level was 66,667%. |
