Abstract
Goal. To find out the influence of substrate compositions made of agricultural residues (barley straw and sunflower husk) on the morphological characteristics of sprouts and individual fruiting bodies of P. citrinopileatus, as well as on the biochemical parameters of fungal raw materials. Methods. Empirical analysis and synthesis, computational and analytical, statistical. Results. Due to the mixing of plant materials in the calculated proportion, the desired ratio of organogenic elements (C/N) was achieved, but the different structures of the components caused a significant difference between the humidity and density of the obtained substrates. It was determined that the composition of the manufactured substrates did not have a statistically proven effect on the main technical characteristics of the growths: weight, size and the total number of fruiting bodies in the sprouts (p>0.05), while the morphological characteristics of individual fruiting bodies differed significantly. Statistically proven dependence of the biochemical composition of fruiting bodies on changes in the components of plant residues in the formula of the substrate was not detected, but the U-test with the use of comparison of the average values had proved an increase in protein in the dry matter to 32.07±0.27% at the use of substrate № 3, which was 8% higher than in fruiting bodies obtained from the substrate № 1. Conclusions. The possibility of using available local agricultural residues (barley straw and sunflower husk) for the cultivation of the fungus P. citrinopileatus, a valuable edible species with proven healing properties, has been determined. The technological characteristics of the sprouts were analyzed, which made it possible to calculate the size of the container to reduce mechanical damage to the mushrooms during packaging. The influence of the substrate composition on the morphological features and biochemical composition of fruiting bodies was statistically proved. A positive correlation was found between the content of ash substances in the substrate and the obtained fruiting bodies.
