KETAHANAN MEDANG (Cinnamomum porrectum (Roxb.)DAN CEMARA GUNUNG (Casuarina junghuniana) TERHADAP KONSENTRASI MERCURI PADA MEDIA TAILING DENGAN INOKULASI FUNGI MIKORIZA ARBUSKULA (FMA)
Abstract: This study aims to
determine the endurance of cemara gunung (Casuarina junghuniana) and medang
(Cinnamomum porrectum) toward mercury toxicity in tailings media and to
determine the level of resistance and the cemara gunung and medang after AMF
inoculated against mercury toxicity in tailings media .The study was conducted
in green house Ex - situ Conservation and Development Research Institute of the
University of Natural Orchid Tanjungpura Pontianak and silviculture in the
Laboratory of the Faculty of Forestry, University of Tanjungpura. The research
was using split-split plot design and each treatment was repeated 3 times. The
treatment consists of : the main plot (the Cinnamomum porrectum (Roxb) and
Casuarina junghuniana), as a subplot (without mycorrhizal inoculation and
inoculated by 25 g mycorrhiza . As sub-sub plot (without Hg, 10 ppm HgCl2, 20
ppm HgCl2, Hg30 HgCl2 30 ppm, and HgCl2 40 ppm parameters observed were : the
level of resistance against the mountain pine medang and mercury
concentrations, the effect of AMF inoculation on plant resistance in mercury
concentration, dry weight of roots and canopy, root shoot ratio, Hg measurement
of root and canopy. Results of analysis of variance and the level of plant
resistance Cinnamomum porrectum (Roxb) and Casuarina junghuniana mercury
concentrations in some significant effect on endurance Cinnamomum porrectum
(Roxb) and Casuarina junghuniana. This is evident in the type Cinnamomum
porrectum (Roxb) with 40 ppm Hg concentrations showed symptoms of poisoning
fastest. While the results of analysis of variance on the type Cinnamomum
porrectum (Roxb) AMF inoculation and Casuarina junghuniana as well as its
interaction with mercury no significant effect on plant resistance.
