Purpose. To reveal the influence of the substrate compositions on technical indicators and the chemical composition of the fruiting bodies of the golden oyster mushroom and poplar mushroom.Methods. The experimental design included cultivation of two species of wood-decay fungi Pleurotus citrinopileatus Singer (strain 2161 IVK) and Cyclocybe aegerita (V.Brig.) Vizzini (strain 2230 IVK) on three variants of substrate composition. Laboratory, laboratory-production methods for evaluating the effectiveness of growing technology, chemical composition of the obtained raw materials, statistical methods of analysis were applied.Results. The structure and composition of substrates affect the technological characteristics of the culture, physical and chemical properties of fruiting bodies. The shortest fruiting cycle of 35.2 ? 1.7 days was determined for C. aegerita under growing conditions on SC1 substrate which formula included ?straw, husks, pellet, rapeseed, corn, and CaCO3? in the ratio of 30: 40: 70: 20: 20: 1. The highest yield (170.5 ? 15.2 g per 1 kg of substrate) in the experiment was determined for P. citrinopileatus on the SC1 substrate composed of ?straw / pellets? / rapeseed / corn /?CaCO3? in the ratio 40: 90: 20: 25: 1. Fruiting bodies of P. citrinopileatus obtained from the SC3 substrate composed of? ?pellets / rapeseed / corn / CaCO3? in the ratio 60: 110: 20: 30: 1 had the highest protein content ? 22.47 ? 0.19%, and fruiting bodies from the SC1 substrate had the least amount of proteins ? 17.38 ? 2.60%. Fruiting bodies of C.?aegerita contained more lipids than those of P. citrinopileatus, but the factor of the influence of the substrate composition on the total amount of lipids for some cultivars was insignificant. The largest amount of endopolysaccharides was isolated from the fruiting bodies of C. aegerita (6.81 ? 0.41%) cultivated on SC3 substrate, and the smallest in the SC1 variant (1.38 ? 0.25%). The content of endopolysaccharides in the fruiting bodies of P. citrinopileatus had less variability from 2.54 ? 0.54 (SC3) to 4.72 ? 0.61% (SC1).Conclusion. Substrate compositions significantly affect the biological efficiency of cultivars and the content of nutrients in fruiting bodies of the studied species. The obtained results enable producers of mushrooms to predict the production efficiency and quality of grown mushrooms in accordance with the use of available raw materials. | ????. ?????????? ????? ?????? ??????????? ?????????? ?? ???????? ????????? ?? ???????? ????? ???????? ??? ????? ??????? ?? ??????? ??????????. ??????. ????? ???????????? ???????? ??????????? ???? ????? ???????????????? ??????

Purpose. Based on the study of consumer qualities of perspective potato hybrids (Solanum tuberosum L.) the ones with a high degree of differentiation depending on the biochemical composition of tubers and culinary-consumer type were identified. Methods. Field (phenology); laboratory (biochemical, technological); mathematical and statistical (linear correlation, regression). Results. Consumer qualities and patterns of their formation under the influence of the biochemical composition of tubers were studied. Excellent taste was determined in mid-early (‘203.703-3’, ‘205.781-9’), mid-season (‘205.786-72’, ‘205. 798-15’) hybrids. High cooking quality of the tubers was detected in early-season hybrids (‘99.523-15’, ‘205.791-3’, ‘205.785-25’, ‘205.792-205’). Soft crispy texture was detected in mid-early (‘205.776-25’, ‘99.546-3’) and mid-season (‘205.782-24’, ‘205.786-72’, ‘205.798-43’) hybrids. The mid-early hybrid '205.780-8' contained high levels of starch. In terms of resistance to browning, three early-season (‘99.517-39’, ‘203.703-2’, ‘205.785-25’) and two mid-season hybrids (‘205.781-9’, ‘205.788-3’) were selected. It is proved, that the taste development depended on the starch content (r=0,657), proportion of starch/protein (r=0,470) and sugars accumulation (r= -450). The positive dependence of the cooking quality of the tubers on their starchiness (r=0,945), proportion of starch and protein (r=0,900) was detected. The influence of proportion of starch/protein over the texture of the tubers (r=0,877) and starch content (r=0,868) was established. Mealiness depended on sugars (r= -0,494) and starch content (r=0,474), resistance to browning – on tyrosine content in protein (r=-0,873) and free tyrosine content (r= - 0,824). In terms of culinary and consumer type of food (table) potatoes, eight hybrids were rated as type B, five and five hybrids belonged to types A and C respectively, and three hybrids belonged to type D. Conclusions. The selected, as for the high level of culinary quality indicators, hybrids can be recommended as valuable output material for practical plant breeding. Determination of biological interrelation of potato culinary quality indicators and biochemical composition of their tubers allowed to develop mathematical simulations to predict taste and texture, and it practically relieved from boiling and subjective evaluation by organoleptic method of tasting results. Systematization of culinary and consumer type food (table) potatoes can be a subject matter in the course of state variety testing.
