Abstract:
The
heavy metal content in area post mine nickel Sorowako reached 14.200 mg.kg-1
and became limiting factor in plant growth. Phytoaccumulator plant of Canavalia ensiformis can be inoculated
with arbuscula mycorrhiza to speed up reduction process. The aim of this
research is knowing ability of mycorrhiza Acalauspora
sp which inoculated on Canavalia
ensiformis to reduce nickel, which prepared base on randomized block design
with treatment of mycorrhiza Acaulospora
sp, i. e: without inoculation of Acaoluspora
sp (control); inoculation of indigenous Acaulospora
sp; and inoculation of non-indigenous Acaulospora
sp. The research conducted in Nursery PT. Vale Indonesia, Sorowako. The results
showed that Canavalia ensiformis
inoculated with indigenous Acalauspora
sp can was increase accumulation of nickel in plant amounted by 7,91 to 11,68%
with reduction rate ranging from 2,25 to 19,02 mg.kg-1.hour-1
and absorption efficiency of 3,19 to 10,10%. The nickel concentrations in Canavalia ensiformis increased of 1.40%
to 2.54%, nickel concentration in root tissue was higher than other organs at
age of 30 to 60 day after planting. This result indicated that indigenous Acaulospora sp could recommendation as
biological agent that can help phytoaccumulator plant at nickel post mine area
in Sorowako.
