Effect of plant extracts on Trametes versicolor (White rot) fungal colonization and inhibition of treated wood samples of Pinus roxburghii Sargent

Abstract

The present studies were conducted on effect of plant extracts on Trametes versicolor (White rot) fungal colonization and inhibition of treated and untreated wood of Pinus roxburghii Sargent. The data on colonization and fungal inhibition were noticed significant variation. Among the concentrations, maximum value for fungal colonization treated wood samples with extract was noticed in the (100%) for the controlled wood samples and minimum was found in 2.00% concentration (12.86%).The maximum colonization was observed in the Acorus calamus extract treated wood samples (59.04) and minimum in Parthenium hysterophorus treated extracts wood samples. In case of solvent used for the extraction, maximum fungal colonization was recorded in petroleum ether extract (58.69%) treated wood samples and minimum (53.38%) in methanol extract treated samples. In case of plant extract and chromium treated wood samples. The data for concentrations, maximum value (76.47%) was found in controlled wood samples and minimum in (10.31%) 2.00% concentration. The maximum value (49.31%) for the extract was noticed in A. Calamus treated wood samples and minimum value (46.84%) in P. hysterophorus treated wood samples. Among the solvent used for extraction maximum value (48.84%) showed in petroleum ether extract treated samples and minimum (47.31%) in methanol extract treated samples. Among the concentrations, maximum value (87.19%) for inhibition treated wood samples with extract was found in the 2.00% concentration treated wood samples and minimum 0.25% concentration. The maximum inhibition was noticed in the P. hysterophorus extract treated wood samples (56.37%) and minimum (49.27%) in the A. calamus extracts treated wood samples. In case of solvent used for the extraction, maximum inhibition was noticed in methanol extract (56.06%) treated wood samples and minimum (49.57%) in petroleum ether extract treated samples. In case of plant extract and chromium treated wood samples. The data for concentration, maximum value (90.41%) was observed in 2.00% concentration and minimum in (10.44%) 0.25% concentration. The maximum value (49.44%) for the extract was noticed in P. hysterophorus treated wood samples and minimum value (43.75%) in A. Calamus treated wood samples. Among the solvent used for extraction maximum value (49.81%) showed in petroleum ether extract treated samples and minimum (43.37) in methanol extract treated samples.
