PENGARUH PEMBERIAN FUNGI MIKORIZA ARBUSKULA (FMA) TERHADAP KANDUNGAN LOGAM TIMBAL (PB) PADA TANAMAN SENGON (PARASERIANTHES FALCATARIA)
ABSTRACT: Plumbum (Pb) is an
environmental contaminant that risk for human’s health, reducing soil fungtion
and productivity and damage for plants. Therefore, remediation is need to do
such as bioremediation using AMF and sengon as a host. A research was conducted
to knowing the effect of the addition of AMF for
Pb content on Sengon in green house of Agriculture USU. Analyze of Pb
metal was done at Research Laboratory of Pharmacy USU on October 2014- February
2015 using faktorial completely randomize design with two faktors, i.e Pb
addition (0 and 400 ppm) and doses of mycorrhiza inoculation (0, 25 and 50 g).
Parameters measured were root colonization, plant height, stem diameter, root
drying weight, crown drying weight, crown root ratio, root Pb content, crown Pb
content and soil Pb content after harvest.The results showed that Pb addition
affected significantly on plant height, Pb content on root, crown and soil
after harvesting parameter. Inoculation of mycorrhiza affected significantly on
plant height, stem diameter, drying weight of root and crown. Inoculation of
mycorrhiza did not significant on Pb content but capable to increasing Pb
content on root, crown and soil. The interaction of the two faktors did not
affected significantly on all parameters.
