Abstract
Experiments on the effect of brassinosteroids and their salicylates on the mycelium biomass during submerged cultivation of oyster mushroom (Pleurotus ostreatus) were carried out. It was shown that their addition to the nutrient medium at a concentration of 0.05 mg/l significantly increases the biomass of the mycelium. It was found that, when exposed to 24- epi- and 28-homocastasterone for 9 days, the mycelium colony developed only in the depths of the culture liquid, and the mycelium was formed into glomeruli with a dense structure. The use of salicylates 24-epicastasterone and 6-deoxo-24-epicastasterone promoted the development of an extensive colony of mycelium both on the surface and in the depth of the culture liquid. Salicylates also influenced the structure of the mycelium – the jellyfish-like loose mycelium was observed in flasks with a medium containing 24-epi and 6-deoxo-24-epicastasterone salicylates. For the first time, the determination of the content of endogenous brassinosteroids in the fruiting body and mycelium of P. ostreatus was carried out.
