CHRYSOPOGON ZIZANIOIDES (L.) ROBERTY ESSENTIAL OIL AS PINUS WOOD RESISTANCE ENHANCER AGAINST THE ACTION OF XYLOPHAGOUS FUNGUS RHODONIA PLACENTA
Main Article Content
Abstract
Background: Plant essential oils have been tested as strategy to increase wood durability and to optimize its use. The aim of the present study is to assess the efficiency of Vetiveria zizanioides essential oil produced in Brazil and in China to increase Pinus wood resistance against the wood-destroying fungus Rhodonia Placenta. Wood specimens were exposed to fungus Rhodonia placenta and treated with these oils at concentrations 10%, 25%, 50% and 100%. Gas chromatography in combination to mass spectrometer was performed to feature the oil components.
Results: The Brazilian oil turned Pinus wood highly resistant to R. placenta and the Chinese one made it partially resistant to this fungus. Brazilian sample presented compounds typical of V. zizanioides, namely: khusimol, β-vetivone, vetiselinenol and β-vetisperene. The Chinese oil only presented few sesquiterpenes, among them, cis-thujopsene, cedrol and pachoulol. Isopropyl myristate was its major component, but it does not have plant origin.
Conclusion: Therefore, Pinus wood is highly susceptible to fungus R. placenta, but it gets resistant to it after being treated with typical V. zizanioides essential oil at concentrations of 25%, 50% and 100%. V. zizanioides essential oil added with additives, such as isopropyl myristate, loses efficiency in making Pinus wood resistant to fungus R. placenta.
