The plant collections of the NDP “Sofiyivka” of NAS of Ukraine including accessions of the subtribe Malinae Rev., formerly the subfamily Maloideae C. Weber (Rosaceae Juss.), are the objects for research in the field of plant introduction and phytodiversity protection. Because of the significant number of park’s holiday-makers, which are not always careful about plants, the posttraumatic regenerative ability of plants is of particular importance for adaptation and periods of the highest regenerative activity could be favourable for vegetative reproduction, including microcloning. Thus, Malinae of the “Sofiyivka” might be useful for germplasm conservation and utilization in the breeding programs.

Ukraine's food security is due to the production of a sufficient number of high-quality, environmentally friendly, high-quality food products of animal origin, including poultry products. The purpose and objectives of the study. To analyze the slaughter condition, safety, and quality of slaughter products of meat turkeys in the direction of productivity when using the prebiotic drug actigen. The object of study was turkeys of the BIG-6 breed. The prebiotic Actigen was added to the essential diet of turkeys in the following doses: from the 1st to the 21st day: 0.4; 0.8 and 1 g/kg of feed; from the 22nd to the 42nd day: 0.4; 0.6 and 0.8 g/kg of feed; from the 42nd to the 120th day: 0.2; 0.4 and 0.7 g/kg of feed. Mixing prebiotics with compound feed was performed with a feed mixer on the farm for compound feed production. The bird had free access to food and water throughout the fattening. According to DSTU 3143:2013, carcasses of broiler turkeys of experimental groups belong to the first category of fattening. The macrostructural characteristics of the organs of broiler turkeys in the experimental groups correspond to the age norm of the bird. Organomacroscopic characteristics of slaughter products of broiler turkeys of all experimental groups do not differ significantly. When determining the organoleptic characteristics of broiler turkey meat after using the prebiotic Actigen, it was established that Volodar LLC, Kyiv region, sells quality products that meet the requirements of the current National Standard. In the study of microbiological and microscopic indicators of broiler turkey meat after the use of the prebiotic Actigen, it was found that the microbiological indicators of MAFANM content in broiler turkey meat of Volodar LLC of the experimental group were 2.12 ± 0.25 × 103 and control groups 2.98 ± 1.07 × 103 according to the norms 1×106 CFU/g – fresh turkey, i.e., met the requirements of the current National Standard. It was found that the broiler turkeys' meat after using the prebiotic Actigen had a higher relative biological value – 100.0 %, compared with the control group of 95.0 % (P < 0.05). The number of Tetrahymena pyriformis cells grown on a nutrient medium with broiler turkey meat after three hours of incubation in the experimental group was 100.0 ± 5.3 – due only to motile cell forms. A similar trend remained after six hours of incubation. Infusoria had the shape of a regular shoe; they are mobile. Therefore, no adverse effect of samples of the meat of turkey broilers of Volodar LLC on the morphophysiological parameters of ciliates of Tetrahymena pyriformis was found, which indicates that the studied meat of the experimental groups is not toxic.

Aim. The study of morphological characteristics of fruits and seeds of the genus Malus is the key to the effective use of the apple genetic diversity in landscape-gardening, fruit growing, introductory and breeding. Methods. Morphological features of fruits and seeds of nine species and three varieties of apple (M. baccata, M. coronaria ‘Red Tip’, M. floribunda, M. fusca, M. halliana, M. niedzwetzkyana, M. × purpurea, M. × purpurea ‘Ola’, M. × purpurea ‘Royalty’, M. × purpurea ‘Selkirk’, M. trilobata, M. tschonoskii, M. toringoides) were studied. Generally accepted tech- niques of research was used. Results. The fruit weight of apple species and varieties varied from 0.30 g (M. fusca) to 61.20 g (M. coronaria ‘Red Tip’), the weight of 1000 seeds — from 5.00 g (M. fusca) to 62.77 g (M. coronaria ‘Red Tip’). The largest number of seeds in the fruit was characteristic of M. toringoides (6.64), the smallest — M. tschonoskii (0.25); developed seeds were not detected in the fruits of M. trilobata for 2019–2020 years. The lowest level of variability among biometric indicators of the studied representatives of the genus Malus was in terms of fruit height, fruit diameter and seed height, the highest — in terms fruit weight and number of seeds in the fruit. Conclusions. Detailed characteristics of fruits and seeds of the genus Malus, growing in the National Dendrological Park “Sofiyivka”, were compiled as a result of research. The obtained data can be used as a supplement to the botanical characteristic, and as a comparative material for taxonomy and phylogeny.
