Особенности биологии гриба шиитаке (Lentinula edodes (Berk.) Pegler) на территории лесного участка ПГСХА «Реликт Приморья»

The shiitake mushroom (a fragrant Japanese mushroom) grows in deciduous forests of Primorye dominated by mongolian oak, mostly on the dead wood of oak. The purpose of the study was the analysis of features of growth of a shiitake mush-room in various climatic conditions. Researches were conducted on the territory of the wood lot of Primorsky state agricultural academy "Relict of Primorye". As the analysis of collected data, the size and weight and in general productivity of shii-take mushrooms showed a complete dependence on climatic conditions (humidity and temperature). Also ventilation played a significant role in the area where marked districts were situated. As favorable condition for good productivity was humidity of air not lower than 78 % and temperature from 18 to 28 degrees Centigrade. Optimum terms and fructifica-tion were revealed: from May to November. Know-ing weather conditions of the forthcoming vegeta-tive period, one can with a sufficient accuracy pre-dict productivity of a shiitake mushroom on the ter-ritory of Primorsky region.
