Apstrakt: "Ispitan je uticaj prouzrokovača mrke prizmatične truleži Coniophora puteana (Schumach.) P. Karst., na gubitak mase i smanjenje pritisne čvrstoće kitnjaka (Quercus petraea agg.). Gubitak mase drveta Q. petraea agg., pod dejstvom gljive C. puteana, posle 2, 4 i 6 meseci inkubacije iznosio je 1.5, 2.12 i 2.23, što znači da je najveći gubitak mase drveta nastupa u prva dva meseca. Utvrđeno je da se pritisna čvrstoća drveta Q. petraea agg. pod dejstvom gljive C. puteana posle 2, 4 i 6 meseci smanjila u odnosu na početnu (100%) i iznosila 92.13, 90.72 i 76.25. Korelacionom analizom gubitka mase - Gm i smanjenja pritisne čvrstoće drveta kitnjaka - p (zavisno promenljive) u odnosu na vreme dejstva gljive C. puteana (T - nezavisno promenljiva), konstatovana je jaka veza između promenljivih i dobijene su regresione jednačine : Gm = 0,0638492 + 0,954107 x T p = 96,328 - 2,666 x T"

Abstract:"The paper examines the effects of a brown rot agent - Coniophora puteana (Schumach.) P. Karst on the mass loss and compression strength of sessile oak (Q. petraea agg) wood. The wood mass loss of Q. petraea agg., caused by C. puteana amounted to 1.5, 2.12 and 2.23 after 2, 4 and 6 months respectively. The obtained values indicate that the biggest mass loss of wood occurred in the first two months. Compression strength also decreased under the influence of C. puteana. In comparison to its initial value (100%), it amounted to 92.13, 90.72 and 76.25 after 2, 4 and 6 months. The analysis of the correlation between the sessile oak mass loss - Gm and compression strength decrease - p (dependent variables) and the incubation time (T-independent variable) revealed a strong correlation between the variables and the following regression equations were obtained: Gm = 0.0638492 + 0.954107 x T p = 96.328 - 2.666 x T"
