[Classification of Softwood according to its biological resistance versus decay fungi depend on Ethanol/Cyclohexan-Extract]

Attributed the biological of resistance of timber to the content of the extracts of wood ((Extract ethanol / cyclohexane)) It gives extracts of wood resin, softwood species biological resistance against fungi, so it was under this research study the possibility of classifying softwood according to the biological resistance versus decay fungi depend on Ethanol/cyclohexane Extract, Note that there are many research known and which addressed the issue of classification of wood of some species conifers and broad leaves, according to the biological resistance and durability where they adopted the method of estimating the biological resistance of wood to study the loss in weight and chemical components (cellulose, Hemicellulose, Lignin) after vaccination of wood Mushroom. However, the classification of wood species according to the biological resistance versus decay Fungi of the wood depending on the content of the wood extracts. (ethanol /cyclohexane) is still not beaten yet in a time when prescription Biological Control of wood, especially against fungi analyst of wood of the most important characteristics that determine the durability and their uses.Has been obtained secondary extract of the following wood species a pine-Halabi Mill( Pinus halepensis) , pine Albroca( Pinus brutia) ,pine fruiting (Pinus pinea L) , cypress Permanent green L( Cupressus sempervirens ), cypress silver( Cupressus arizonica) , tannins eastern (Biota orientalis) ,Lebanese cedars(Cedrus libani) , fir Syrian (Abies cilicica) , Allmab Beib( Juniperus excels)using the technology of ethanol cyclohexane of heart wood, was then test the effect of several concentrations of these extracts in mushrooms \{Shiitake Lentinula edodes (Berkeley)\} sensitive to wood conifers and sleep get the following results: 1-decrease in the average growth dimeter of fungal colony within each type measured with increasing concentration of ethanol / cyclohexane of wood, which increases the biological resistance of the kind of wooden increasing concentration of ethanol / cyclohexane extract of its wood. 76 2-notes the hinder of growth Misaleom mushrooms at concentrations of 200 ppm, 250ppm, 300ppm, 600ppm extract ethanol / cyclohexane the wood of Cypress permanently green and cypress silver and tannins east and cedars lebanese and Allmab while enabling Misaleom fungus to grow at the same concentrations of ethanol / cyclohexane extract of the wood of fir and pine-Halabi and Albroca and fruiting, this means that the biological resistance of against the fungus for wood of fir and pine-Halabi and Albroca and fruiting is less than the biological resistance against the fungus for wood of Cypress permanently green and cypress silver and tannins and cedars lebanese and Allmab.3- the lack of significant differences at p = 0.05 between the average diameter growth of fungi colony for the species of the same Genera pinus or cupressus, it means the species of the same Genera have similar biological resistance against fungus Genera which prove similar to the chemical composition of ethanol extracts / cyclohexane extract for their timbers.4-increasing biological resistance against the fungus ascending order according to the following: fir - pine (Prouty, Halabi, Thamari) - Cypress (permanent green, silver) - tannins Eastern - Lebanese cedars - Allmab. And match this result with the International Classification of wood as the biological resistance of the fungus damaged wood and adopted in the European standard Norms:EN:350-21/1994.5- match each of the statistical , biological , (ED50, toxic lines) and photographic results with the International Classification of wood as the biological resistance of the fungus damaged wood and adopted in the European standard norms.
