2013
Н. В. Лещук | Н. П. Костенко | Н. В. Павлюк | В. А. Павлюк
The article discloses the meaning of botanical semantics, highlights practical appliance of binary scientific botanic nomenclature during plant varieties identification. It is the binary nomenclature of introduced cultivars that requires a scientific approach to structuring and developing the methodological and source learning database of botanical names in Ukrainian and Latin. According to the results of analytic monitoring, research aspects of differentiation of systematic units are shown, as well as certain rules and recommendations concerning theoretically sustained names of botanical taxa in Ukrainian and Latin. The scientific search for harmonization will enable to improve the practical appliance of methodological and linguistic and orthographic requirements and rules of spelling for botanical taxa names during the registration of rights on them. Spelling harmonization by Linnaeus semantic (in Latin) will facilitate a uniform approach to updating methodological and source studying database of binary names of the introduced cultivars of botanical taxa.

С. П. Полторецький
The objective of the research is to improve the technology of growing high-quality seeds of millet broomcorn by means of the optimization of sowing terms and methods, aimed at increasing its productivity and improving seed qualities under conditions of unstable moistening of the Right-Bank Forest-Steppe of Ukraine. Scientific literature review indicates the study of the influence of these technology elements on the formation of sowing qualities and crop capacity of millet seeds has been of schematic and occasional nature. The issue has not been studied in this region condition at all, that is why the research has considerable significance and novelty. Analysis, observations and calculations were done by means of conventional methods. Research results indicate that under conditions of unstable moistening of the southern part of the Right-Bank Forest-Steppe of Ukraine the highest yield of Slobozhanske and Lana varieties was reached at sowing in drills – 39.2 and 41.0 metric centners per hectare, respectively. That was 2.4 and 3.9 metric centners per hectare increase against the wide-row sowing. In the years with optimal hydrothermal conditions maximum seed productivity of millet broomcorn at the level of 4.24 to 4.79 metric tons per hectare (Slobozhanske variety) and 4.53 to 5.28 metric tons per hectare (Lana variety) was observed at postponing the sowing terms to the third decade of May. If atypical for the region hydrothermal conditions (drought or excessive moistening) are forecasted du ring the vegetation period of millet, the highest productivity is provided by sowing in the second decade of May. Early sowing in the first decade of May causes decrease in yield at the level of 0.14 to 0.48 metric tons per hectare (Slobozhanske variety) and 0.14 to 0.48 metric tons per hectare (Lana variety); if the sowing is postponed to the first decade of June, the yield increases by 0.31 to 0.77 and 0.39 to 0.84 metric tons per hectare, respectively. Early spring and summer sowing using ordinary drill method contribute to the formation of the highest qua lity of seeds – the overall quality index was the highest at the level of 97,9 to 98,5% (Slobozhanske variety) and 98,3 to 100,0% (Lana variety).

Н. О. Горган
Collection samples of the onion of varying ecological and geographical origin have been scrutinized under the conditions of Chernigiv region to establish their susceptibility to Botrytis allii Munn pathogen. It is noted that the disease develops, first of all, on samples with dry leafs colored white, and established that enhanced resistance to the pathogen is inherent in forms of anthocyanin or red coloration or dry and damp skins (Rubin, Amfora, Veselka, Mavka, Braushverska Chervona, Venta F1, Tango F1, Golubka). Sources of resistance to neck rot are indicated (Olina, Texas Curli, Violetta, Red Baron F1), which have not been damaged by the pathogen at all through the three years of study. The use of parental pars quality of such samples will enable to produce prospective breeding material at hybridization.

Purpose. To study effects of low temperatures on Lavandula angustifolia plants and their response depending on their age and variety as well as identify critical temperature values for such structure elements of plants as bark, cambium, wood, pith. Methods. Field investigation, spectrometric analysis, statistical evaluation. Results. Topicality of investigation of Lavandula angustifolia to be grown in the Forest-Steppe zone of Ukraine was highlighted. Low temperature effects on structural elements of shoots for 8 varieties of domestic and foreign selection were analyzed. One-year shoots have suffered the most from low temperatures – 4.5 points on a six-point scale, two- and three-year shoots were damaged in a lesser degree – from 0.8 to 2 points. Plants of ‘Feuervogel’ and ‘Maestro’ varieties with total damage coefficient of 11.3% and 10.6% accordingly were the most resistant to low temperatures. These varieties can be recommended to producers for further introduction to the Forest-Steppe zone of Ukraine. Conclusions. Tissues of a lavender one-year shoot were most damaged by low temperatures regardless of a variety, but this organ is ephemeral and can be removed without causing damage to a plant. Two- and three-year shoots, which provide plant recovery, were significantly less damaged. None of the plants from 8 studied lavender varieties was lost under the influence of low temperatures, though some of them were damaged significantly. Such varieties as ‘Feuervogel’, ‘König Humbert’, ‘Veseli notky’ (pith damage is on the level of 1–2 points), ‘Maestro’ (0.8–2.5 points) were the most resistant to low temperature exposure which allows to conclude about successful lavender cultivation under conditions of the Forest-Steppe zone of Ukraine.
