Impact of Infections with two Trichoderma Aggressivum F. Europaeum Isolates on the Yielding of Some Wild Strains of Agaricus Bisporus (Lange) Imbach

Abstract

Abstract:The effect of infections with Trichoderma aggressivum f. europaeum on the yielding of seven wild and one commercial strain of Agaricus bisporus (Lange) Imbach. was investigated. Wild strains of the mushroom were derived from natural habitats of Poland. The cultivation substrate was inoculated with two different isolates of T. aggressivum f. europaeum Th2. It was found that infections of the substrate with these isolates resulted in a very serious decrease in mushroom yield. The examined mushroom strains showed different reactions to the infections with Trichoderma isolates.

Impact of Trichoderma Pleurotum and T. Pleuroticola Isolates on Yielding of Pleurotus Ostreatus (FR.) Kumm

“…Earlier investigations conducted by the authors concerning the impact of T. aggressivum f. europaeum showed that Agaricus bisporus strains are characterised by different resistance to the infestation with the above-mentioned Trichoderma species. We found that brown strains responded to the infestation with lower yield losses than white strains (Sobieralski et al 2009). The performed experiments failed to demonstrate significant differences in the response to T. pleurotum and T. pleuroticola infestation between the two examined P. ostreatus strains.…”

Effect of Trichoderma Isolates on Yielding of Wild Strains of Coprinus Comatus

“…on yields of the common mushroom mycelium. Researchers demonstrated, a considerable decline of yields of A. bitorquis in the case of its infestation with the T. aggressivum f. europaeum isolate (Sobieralski et al 2010a). Moreover, they also demonstrated that the response of the common mushroom strains, gathered from natural sites, to substrate infestation with the examined T. aggressivum f. europaeum isolates, varied significantly.…”

“…The abovementioned strains constitute biotypes of a non-aggressive form of T. harzianum in relation to cultivated mushrooms. The aggressive strains differ from non-aggressive forms, primarily, by the speed of mycelium growth (Samuels et al 2002;Sobieralski et al 2009). The cultivation of Agaricus bisporus is technologically similar to the cultivation of Coprinus comatus.…”

Genomic Analyses Reveal Evidence of Independent Evolution, Demographic History, and Extreme Environment Adaptation of Tibetan Plateau Agaricus bisporus

“…Its wild resources were first discovered in Europe, and then the American population was reported (Callac et al, 1993; Kerrigan et al, 1998). With continuous investigation and collection, the distribution of wild resources was reported in Canada, Israel, Morocco, and the central and western regions of Africa (Kerrigan, 1995; Kerrigan et al, 1995; Sobieralski et al, 2010; Mata et al, 2016; Rokni et al, 2016; Sonnenberg et al, 2017). In the 1970s, wild A. bisporus was first discovered in the Tibetan Plateau (Wang et al, 2012), which need to withstand harsh environments such as alpine, anoxic, and strong ultraviolet rays.…”
