Growth Intensity of Trichoderma Viride at Different Doses and Sources of Copper in the Medium

The biological properties of Trichoderma Viride fungi allow them to be effectively used in the technologies crop waste disposal, production organic, environmentally friendly fertilisers, and prevention soil diseases plants. growth development these depend on a number trace elements that are found medium. Copper is great importance among elements. establishment ability use copper as stimulator biomass accumulation scientific practical interest for national economic needs, which indicates relevance study. purpose study establish effectiveness effect various compounds Viride. To investigate metal-biotic microorganisms, 0.5 10.0 mg/100 cm3 element form sulphate, mixed ligand complex glycinate were added medium with potato dextrose agar (PDA). In control variant, was not nutrient media inoculated Viridin preparation. recorded days 4 7 experiment. It has been experimentally established fungal population affected by content source presence biotic metal mineral or chelated up 1.0 stimulates build-up biomass. proved 4th day cultivation introduction into amount mixed-ligand form, increased 75.0%. On 7th day, increase cells 58.3%. more than 5.0 any decreased. higher medium, greater inhibition cell reproduction. generalised comparing action copper, glycinate, it latter compound most toxic against
