Influence of traditional (heteroauxin and gibberellin) and growth stimulators of new generation (fumar and biogumat) on development of vegetative mycelium Pleurotus ostreatus at surface cultivation on agar nutrient medium is investigated.

Fumar in concentration of 10–3% and 10–4% and biogumat in concentration of 10–2% render positive effect on radial growth rate of mycelium. The heteroauxin in concentration of 10–4% inhibits mycelium in phase of linear growth.

The examined growth stimulators influenced positively on formation of the teleomorphos stage, especially fumar and biogumat. Quantity increase of primordias on the nutrient medium under addition of fumar and biogumat shows growth stimulators influence on morphogenesis processes of the tested basidial mushroom.

.Key words: growth stimulators, heteroauxin, gibberellin, fumar, biogumat, linear growth rate of mycelium, primordias.
