A Comparison of Physical Properties of Hang Together and Mistletoe Defect of Iran wood Branches and Stem Normal Wood

This study examines physical properties of hang together and mistletoe and normal Iran wood branches. For this purpose three healthy parratia persica tree were selected in altitude levels 200 and 400 meters at 20vat FORESTRY project. From each tree, three discs for three portion of hang together and mistletoe and normal branches of trees were cut down. Samples of discs prepared to measure physical properties including oven-dry Density , basic density, volumetric shrinkaya and volumetric swelling. The analysis of variance showed that the effect of branches on the oven-dry density, basic density ,and longitudinal shrinkaya was significant and on the volumetric shrinkaye ,tangential shrinkaye and radial shrinkaya wasn’t significant. Trend changes more then of wood basic density ,oven-dry density and longitudinal shrinkaye in hang together branches but mentioned changes in the normal and mistletoe branches were approximately equal. The results showed that misttetoe branches as plants pest didn’t howe negative effect on the physical propertieses of wood.
