The Potential of Rhizospheric Fungi From Critical Land of Sub-District Cempaka, South Kalimantan as Fe-Absorbent on Calopogonium Mucunoides Plant

Abstract

Exploiting the rhizospheric fungi from critical land area is one way to know the ability of the fungi to absorb Fe. Calopogonium mucunoides which used as experimental plants in this study was capable to grow well in critical land area of Cempaka Sub-District. The study was begun with the isolation of rhizospheric fungi of critical land district Cempaka, followed by calculation of soil Fe content of the critical land areas, selection of the fungi bae on its ability to absorb Fe and fungal spore application to C. mucunoides growth. Humicola sp. R.Dn (from rhizosphere of Dianella nemorosa Lam.) has better ability to absorb Fe than with two other isolates, i.e.Penicillium sp. R.Ha and Penicillium sp RG. Humicola sp. R.Dn could uptake 108.83 mg Fe/mg biomass and giving 2.38 x 103 of Humicola sp. R.Dn spore significantly affected on the reduction of plant Fe content.
