TOLERANSI SIMPUR AIR (Dillenia suffruticosa) TERHADAP BERBAGAI KONSENTRASI HgCl2 DI MEDIA TAILING

Abstract

Research on Dillenia suffruticosa tolerance for Hg in the tailing was conducted in July to August 2012 at Tanjungpura University Pontianak. This research aimed to determine the tolerance of D. suffruticosa to Hg. It used Randomized Completely Design (RCD) with 5 level Hg concentration (0, 10, 20, 30, and 40 ppm) and 3 replications. Data analyzed use Anova test and Duncan test to see D.suffruticosa poisoning symptoms to Hg concentration. The results was that the whole plants showed symptoms of Hg posioned, especially in 30 and 40 ppm. D. suffruticosa can be concidered as phytoremediation agent for Hg contaminated land but less tolerance to high Hg concentration.
