摘要

The research was oriented to the observation of production rate of oyster mushrooms (Pleurotus ostreatus) on beech (Fagus sylvatica) and aspen (Populus tremula) stumps. The primary aim of experiments was to verify assumption about faster decomposition of wood after careful infection with wood destroying mushroom Pleurotus ostreatus as well as the effect of an intensity of fruit body creating on the chemical composition of wood. The highest mean value of biological efficiency (B. E.) (29. 05 %) was found on beech stumps. Relatively high values of B. E. were recorded also on aspen stumps (21.69 %). Maximal value of B. E. on individual stump reached 47.75 % on beech stump and 45. 10 % on aspen one. Minimal value of B. E. was 7.79 % on aspen stump and 17. 51 % on beech one. Total yield of fruit bodies from 40 beech stumps was 353 695 g, more than twice above the total production on 44 aspen stumps (157 100 g). Maximal values of production were reached in the third year. Inoculated stumps had in average about 37% higher content of N than control ones. The ash content was about 90 % higher in inoculated stumps. The share of mineral elements Ca, Mn, Zn, Cu, Pb, Al, B, and Mg has an increasing tendency in inoculated stumps. The only element with a significant decrease (25%-74 %) of its content in inoculated stumps was K. The stumps with a minimal production of fruit bodies and the stumps with the lowest value of B. E. had the highest share of the mineral elements Pb, Al, Fe, Mg and P.

E.值（21.69％）。单个树桩上的B. E.最大值在山毛榉树桩上达到47.75％，在一个白杨树上达到45. 10％。在白杨树桩上，B。E.的最小值为7.79％，在山毛榉一树上为17. 51％。 40个山毛榉树桩的子实体总产量为353 695 g，比44个白杨树桩的总产量（157 100 g）高出两倍以上。第三年达到了最大的生产价值。接种的树桩平均含氮量比对照树桩高约37％。接种的树桩中的灰分含量高约90％。矿质元素钙，锰，锌，铜，铅，铝，硼和镁的份额在接种树桩中有增加的趋势。接种树桩中唯一含量显着下降（25％-74％）的元素是K。子实体产量最低的树桩和BE值最低的树桩中矿质元素Pb的比例最高。 ，铝，铁，镁和磷。
