Purpose. To study interactions among the representatives of the genus Salix L. through the cluster analysis, form groups of closely related species and hybrid forms basing on differences of morphological parameters of leaves. Methods. Field, cluster analysis and tree graphics. Results. Willow species were grouped according to absolute parameters of leaf, and three groups of clusters were identified. The degree of affinity between species were assessed using values of an Euclidean distance. Distinctive features of leaf parameters were defined: length of a leaf blade (Ll), distance (cm) between the leaf tip and its maximum width (SDmxT) and the distance between the leaf tip (cm) and the line of its width that corresponds to the length of petiole (SLpT). Conclusions. Using the willow species collection as an example, diagnostically valuable quantitative parameters of leaves were revealed, the use of which allows to identify willow species and hybrid forms through PC applications.

Purpose. To analyze the types of license agreements and their difference from other civil agreements, and requirements for the execution and termination of a license agreement. Results. It was revealed that the current legislation provides an inexhaustible list of the types of transactions with respect to disposition of intellectual property rights. The group of agreements on disposition of intellectual property rights includes the intellectual property license. The legislation provides for three types of license agreements under the terms of the exclusive, non-exclusive and single license. The result of a license agreement is to provide the intellectual property rights for temporary use without losing the copyright holder of this object. Conclusions. Proper execution of license agreements between licensor and licensee promotes protection of rights of each of the parties to such agreements. Licensee will have a legitimate reasons to use the variety, the licensee may receive compensation for granting the right to use the variety.

Purpose. Determination of optimum dozes of foliar fee­ding for each cultivar that will provide the highest output of standard rootstocks. Methods. Field, analytical and statistical ones. Results. The author presents the results of study of the hazelnut plant foliar feeding in the mother plantation for vegetative propagation with applying different carba­mide concentration combined with 0.1% potassium sulfate (1.50.4 m) in case of horizontal method of growing. Biometric indices of hazelnut layers were analyzed; the influence of each factor on their height and diameter was determined. The rootstocks output per 1 linear meter for each cultivar as well as optimum foliar feeding doze was defined (0.5% carbamide with 0.1% potassium sulfate). Conclusions. The highest output of standard rootstocks in the mother plantation for horizontal vegetative propagation was achieved when applying the foliar feeding with 0.5% carbamide combined with 0.1% potassium sulfate, particularly (thousand rootstocks per 1 ha) for the cultivars: ‘Sviatkovyi’ – 66.7, ‘Dolynskyi’ – 62.1 and ‘Darunok Yunnatam’ – 50.7. For ‘Koronchatyi’ cultivar, the use of 3% carbamide was the most efficient.

Purpose. Determining prospects of introducing Callistephus chinensis cultivars of foreign breeding for further cultivation under conditions of the Central Forest-Steppe zone of Ukraine. Methods. Field, laboratory, analytical and statistical ones. Results. Ten C. сhinensis cultivars of theGerman breeding were tested under conditions of the Central Forest-Steppe zone of Ukraine. Biomorphological traits of the varieties of five sort types were identified, and their comparative analysis was conducted. Seasonal dynamics of growth and development of cultivars in the growing area was studied. Conclusions. Cultivars with short and mean duration phases of development can be grown under conditions of the Central Forest-Steppe zone of Ukraine by direct sowing that does not affect their seed productivity and sowing quality of seeds. Seeds of late cultivars can reach complete maturity only in case of seedling use. C. chinensis cultivars of the German breeding have successfully passed the initial test for suitability to introduction into the studied area.

Nomenclature of genus Vaccinium considered, as well as the application of names for indigenous and introduced species and denomination of fruit crops as derived from those species. System of binary species names for Vaccinium s.l. has been proposed as based on the Ukrainian generic name ‘lokhina’ that best complies with the principles for establishing generic names.

Purpose. Revealing of adaptive properties of plant varieties of red beet Bordeaux Kharkivskyi and Aktion based on the study of plant growth regulators for marketable production in the Steppe zone of Ukraine. Methods. Field, laboratory ones, variance analysis. Results. The influence of plant growth regulators (Lignogumat, Betastimulin) on earliness and productivity of such red beet varieties as Bordeaux Kharkivskyi and Aktion was established. Conclusions. Plant growth regulators (Betastimulin, Lignogumat) stimulated seed sprouting of red beet Bordeaux Kharkivskyi and Aktion varieties, activated vegetative plant growth increa­sing marketable yield. Application of Betastimulin (0.2%) for red beet Kharkivskyi Bordeaux and Aktion varieties provides the highest number of marketable beetroots, thus forming marketable yield of 44.7 and 54.9 t/ha respectively with the average beetroot weight of 328–519 g.

Purpose. Identifying new scab-resistant apple varieties with high biological potential by the set of agronomic characters and the ability to realize it effectively in various soil and climatic conditions. Methods. Field, laboratory, comparison, generalization, statistical ones. Results. The author presents the results of study of 17 scab-resistant non-irrigated apple varieties on a semi-dwarf rootstock as to their adaptability to biotic and abio­tic stressors as well as their economic productivity. The studied varieties appeared to be winter-hardy, frost- and heat-resistant, but medium drought-tolerant ones. They are characterized by weak and moderate susceptibility to powdery mildew, high resistance to fruit rot and very low amounts of brown spot, except for Gold Rush variety. Such 10 year old varieties as ‘Edera’, Florina’, ‘Amulet’ and ‘Perlyna Kyieva’ and 8 year old ‘Afrodita’, ‘Vitos’, ‘Orlovskoie Polesie’ and ‘Topaz’ formed the highest productivity during the years of study. Due to the pollen quality and high interfertility, ‘Revena’ and ‘Gold Rush’ varieties were identified as universal pollinators for winter scab-resistant apple varieties. Conclusions. Such ecologically resistant winter varieties as ‘Topaz’, ‘Freedom’, ‘Edera’ and autumnal ‘Remo’, ‘Afrodita’, ‘Vitos’, ‘Amulet’ were recognized as promising for new intensive non-irrigated plantations in the Forest-Steppe zone of Ukraine. They can be the basis of new gardens occupying 25–30% of the area where ecologically safe fruits for various target purposes will be grown supplying demands of the population and processing industry.

Purpose. To study the effect of growth regulators EpinTM and Emistym C on yield and quality of strawberry berries of five varieties (Fragaria ananassa (Weston) Duсhesne ex Rozier) with various ripening time. Methods. Field, laboratory, analytical and statistical ones. Results. It was found that there were no impact of growth regulators EpinTM and Emistym C on the speed of phenological phases of strawberry plants development. It was experimentally determined the impact of mentioned substances on the yield of most studied varieties. Laboratory analysis has confirmed the changes in biochemical composition of strawberries. Conclusions. The use of growth regulators EpinTM end Emistym C had a positive effect on fruit yield and quality of studied strawberry varieties. Spraying with these substances increased yields by 14–51% as compared with the control. Content of sugars, dry matter and vitamin C in berries of most of varieties was increasing. At the same time the level of acidity in case of spraying with growth regulators was significantly reducing.
