Diversity of Sonneratia Alba in Coastal Area of Central Java Based on Isozymic Patterns of Esterase and Peroxidase

Abstract

Setyawan AD. 2009. Diversity of Sonneratia alba in coastal area of Central Java based on isozymic patterns of esterase andperoxidase. Nusantara Bioscience 1: 92-103. The study was intended to observe the diversity and the relationship of Sonneratia alba insouthern and northern coast of Central Java Province based on isozymic patterns of esterase and peroxidase. This research wasconducted in July until December 2003, at six sites, i.e. Wulan (WUL), Juwana (JUW), Pasar Bangi (PAS), in the northern coast, andBogowonto (BOG), Motean (MOT), and Muara Dua (MUA) in the southern coast. The laboratory assay was conducted in CentralLaboratory of Mathematics and Natural Sciences, Sebelas Maret University (UNS) Surakarta. The seedling plant samples that werecollected from enam mangrove habitats transplanted in green house in the laboratory. There were 20 individual samples each sites. Theresult indicated that the individual of S. alba of the same or near location has the same genetic diversity in common, because the geneticexchange on a same population was higher than on a different population. Therefore, the populations of S. alba from northern coast hadhigher similarity each others than southern coast one, on the other way the populations from southern coast had higher similarity eachothers than northern coast one
