spawn quality plays an important role in successful production of medicinal mushrooms. in this study, firstly, to determine the optimum temperature for mycelia growth of g. lucidum, four basal media, including seeds of wheat, barley, millet and abies sp. wood chip were studied separately at 25±1˚c and 29±1˚c. in the second section, in order to achieve suitable the mycelia growth, barley, wheat ...

the aim of this study was to develop an optimal sustainable forest plantation based on goal programming and analytic hierarchy process (ahp) methods. this study was carried out in guilan province, north of iran. first of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological makhdoum model by m...

In declining broadleaf forests in western Ukraine, several Phytophthora species including P. plurivora, bilorbang, polonica, gonapodyides and cactorum were recovered using soil baiting assays identified morphological molecular methods. Pathogenicity tests of selected isolates performed on black alder (Alnus glutinosa (L.) Gaerth.) silver birch (Betula pendula Roth.) to assess susceptibility the...

this study was carried out to determine the chemical composition and degradability parameters of dm, adf and ndf in alnus subcordata saw dust (sd) biodegraded by phanerochaete chrysosporium and pleurotus ulmarius fungi. the sd samples were incubated by the fungi at 30 ± 1˚c and 65 ± 5% relative humidity for 7 and 17 days. biodegraded samples were sterilized to constant activity and oven dried f...
