520			_aRubber wood (Hevea brasiliensis) treated with different concentrations of aqueous solution of chromic acid (2.5, 5, 7.5 and 10;) followed by heat treatment was assessed for its bio-resistance against brown rot and white rot fungi. Though these treatments imparted considerable water repellency in the wood, the invasion of fungal hyphae could not be completely prevented. These treatments have imparted very high resistance against white rot fungi even at the low treating solution concentration of 2.5;. But, the highest concentration (10;) could not give equally significant resistance in case of brown rot fungi. High effectiveness of these treatments against white rot fungi may be attributed to the formation of chromic acid-lignin water insoluble complex.
