Abstract
The present study entitled “Studies on effect of Acorus calamus L. extract on wood characterstics of Morus alba L. wood was carried out during 2021-2022 and 2022-2023 in the laboratory and wood workshop of the Department of Forest Product, College of Forestry, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan. Wood samples were prepared and dipped in Acorus calamus L. (rhizome) extract treated with petroleum ether, methanol and water for 72 hours at different concentration 0.25, 0.50, 1.00, 1.50 and 2.00 per cent to examine the physico-chemical and mechanical properties of Morus alba L. wood. The highest value (119.67%) for maximum moisture content (%) was observed in untreated wood samples and the lowest value (114.45%) in wood sample treated with petroleum ether extract at 2 per cent concentration. The maximum specific gravity (0.557) was found in petroleum ether extract treated wood samples at 2 per cent concentration while the minimum (0.546) in untreated wood samples. The maximum volumetric swelling co-efficient (8.90%) and volumetric shrinkage co-efficient (6.66%) was observed in untreated wood samples and minimum volumetric swelling co-efficient (8.27%) and volumetric shrinkage co-efficient (6.31%) was noticed in petroleum ether treated wood samples at 2 per cent concentration. The highest cold water soluble extractives (4.75%), hot water soluble extractives (6.50%) and alcohol benzene soluble extractives (11.10%) was recorded in water extract treated wood samples at 2 per concentration while the lowest cold water soluble extractives (4.46%), hot water soluble extractives (6.16%) and alcohol benzene soluble extractives (10.66%) was observed in untreated wood samples. The maximum tensile strength (0.074 kN/mm2), bending strength (0.011 kN/mm2), compression parallel to grain (0.057 kN/mm2) and compression perpendicular to grain (0.019kN/mm2) was found in petroleum ether extract treated wood samples at 2 per cent concentration and minimum tensile strength (0.071 kN/mm2), bending strength (0.008 kN/mm2), compression parallel to grain (0.055 kN/mm2) and compression perpendicular to grain (0.018 kN/mm2) was observed in untreated wood samples. In paint application, the highest maximum moisture content (134.64%), volumetric swelling co-efficient (10.65%) and volumetric shrinkage co-efficient (8.24%) was noticed in absolute control whereas, the lowest was recorded in 100 per concentration which was statistically at par with 95 per cent paint with 5 per cent thinner concentration and upto 75 per cent paint with 25 per cent thinner concentration.
