NATURAL RESISTANCE OF WOOD A wood-destroying fungi under laboratory conditions
Abstract
The research aims to assess the natural resistance of the seven species of wood fungi
wood decay in laboratory conditions. Species tested were leucaena (Leucaena leucocephala (Lam.) De Wit.), Blond-brown (Cordia trichotoma Vell. Former. Steud.), Jurema in (Mimosa tenuiflora (Willd.) Poir.), Quince-black (Croton sonderianus Muell. Arg.), thrush (Mimosa caesalpiniifolia Benth.)-Indian neem (Azadirachta indica A. Juss.) and teak (Tectona grandis Lf.). Of each species body-of-proof 2.54 x 2.00 x 1.00 cm were removed, with the largest dimension in the direction of the fibers, in four positions from pith to bark. The samples were subjected for 98 days to fungi Postia placenta (Fr.) MJ Lars. & Lomb. or Polyporus fumosus Pers. ex Fries. Woods jurema in and thrush were the most resistant, while neem and quince the most likely. Samples from the outside of the trunk suffered the greatest losses in mass. P .placenta attacked more severely tested woods.
