“…It is known that in the flowering phase, the aerial mass of H officinalis contains up to 1.5% of essential oil in terms of dry weight; flavonoids (apigenin, luteolin, quercetin), their glycosides and phenolic acids (chlorogenic, protocatechuic, ferulic lilac, phydroxybenzoic coffee, vanillin, p-coumaric, rosmarin and gentisin); Vitamin C and carotene, along with many other substances [5][6][7]. The essential oil of H. officinalis, which is obtained in many countries of the world, is of great interest [8][9]. The chemical composition of H. officinalis essential oil was studied in various parts of the world, and according to the results of most studies, the main components are pinocamphone and isopinocamphone [5][6][7][10][11][12][13].…”

The sterilization process of plant explants of H. officinalis was optimized when introduced into an in vitro culture, the most effective sterilization modes, optimal sterilizing agents, their exposure time and concentration were selected. Callus tissues and mini-plants of H. officinalis were obtained in vitro and the most optimal nutrient media were determined both for microclonal propagation and for the induction of callus tissue H. officinalis, which can be further used for mass cultivation of cell and culture and obtaining safe bio-additives with active substances for livestock and crop production as a part of the development of modern agrobiotechnologies.

Potential crop productivity can be achieved under meeting the requirements on biological needs of crops on their nutrition area twith essential number of nutrients, optimum temperature, lighting and moisture supply. Growing medicinal and essential oil crops leads to uneven seedling in unstable temperature conditions of the spring period. Therefore, it is important to determine the favorable time for sowing, as well as the optimal placement of plants in the area aimed at the seed germination energy growth as well as good and even sprouts. Sowing time and methods influenced Clary sage seeds germination. The highest seed germination rate was observed with a sowing period of April 15 and a wide-row sowing method of 45 cm – 92,3 %. These techniques contributed to better survival of Clary sage plants at the end of the growing season (fruit formation phase) as well, the figure was 95,1 %. The highest growth rate of Clary sage (6.1–14.1) cm was observed in the period of complete formation of leaves rosette. By the budding phase, its growth was slow – 2–3 cm in ten days, and from budding to flowering the crops growth rates significantly increased to 8–10 cm. After the flowering phase, the growth of Clary sage decreased, which ensured a uniform redistribution of nutrients from the vegetative to generative part. The greatest crops height was noted for the winter period of sowing and row spacing of 15 cm (31.8 cm). A change in the ratio of accumulation of crops green mass parts (stems, leaves, inflorescences) was observed in the process of Clary sage growth and development. So, in the budding phase, the share of leaves was 1.9–2.9 % of the total plant weight and in the fruit formation phase it made 3.6–5.9 %. The same trend was observed in the change of the total stems weight. An increase in the row spacing (up to 45) influenced the growth of Clary sage biomass. In the fruit formation phase, the total plant weight increased by 0.4–3.1 g in comparison with that under 15 cm row spacing Late sowing dates for Clary sage (April 15) contributed to the formation of a larger number of stems, leaves and inflorescences on the plant. The total number and productive inflorescences was larger under 15 cm width method of sowing, which is more than those compared with the wide-row sowing of 45 cm. Solid sowing method (15 cm)provides a larger number of Clary sage stalks, but only in subwinter sowing. Indicators of individual productivity of Clary sage such as stems, leaves and inflorescences number determine the optimal application of growing technology methods to realize the potential of this crop. The most favorable conditions for Clary sage high productivity formation are created for a sowing period of April 15. Maximum values of crop production were obtained with a row spacing of 30 cm. The enhancement of plant density (with a row spacing of 15 cm) results in Clary sage productive inflorescences number increase. Consequently, the maximum values for Clary sage plants (average data for the experimental sites) were noted with a sowing period of April 15 with 45 cm row spacing (plant weight – 17.6 g, leaves weight – 5.7 g, inflorescences weight – 5.3 g). Key words: Clary sage, sowing time, row spacing, phenological phases, green weight, leaves, inflorescences.

Seedlings planting terms and row spacings influence on fennel seed yield formation

Fennel is a perennial plant though the crop is used as biennial. Growing fennel seedlings and planting it in open ground at the phase of 4–5 leaves reduces the growing season and increases crop productivity of the plant. The beginning of growth phases and development of fennel plants depends on the seedlings planting time. The accelerated process of the crop budding phase is noted at its early planting on April 20. The large-scale flowering of fennel was noted only 19 days after planting and fruit formation – after 27 days for seedlings planting on May 10. It was found that linear growth of seedlings at the early stage of planting (April 20) was the largest at row spacing of 15 cm and was 38,6 cm at the flowering period of fennel, that is 12,2 cm larger than in the 45 cm row spacing. The linear growth of crops in the main phases of fennel vegetation was lower for planting seedlings on May 10 compared to April 20. A faster acceleration of the growth and development phases as well as linear growth of fennel was noted for early planting of seedlings – on April 20. After planting fennels seedlings in the open ground, it was found that plants grow slowly (2–3 cm per decade) until the budding stage, and from the budding to fruit formation stage the growth rate of plants increased by 11.0–17.8 cm. Phenological observation of fennel plants leaf apparatus formation was carried out immediately after the shoots appearance. It was established that the first pair of true leaves formed in 10 days after sowing of seeds in the greenhouse, and the fifth pair of leaves – in 50–55 days. The leaves weight grew most during the budding stage – the fruit production of fennel plants depended on the seedlings planting time. The maximum value was noted for planting on May 10 and for 45 cm row spacing and made 10.86 g. The main indicator of fennel performance is its fruits and seeds weight. Plant mass and its individual parts grew and the ratio of green mass parts changed during the growth and development of the crop. Thus, the leaves weight on the experimental sites was 2.1–3.1 g or 37.5–38.3 % at the budding phase. Leaves weight was 4.7–7.8 cm2/m2 or 38.0–51.7 % during the fennel fruit formation. At the budding phase the leaves weight increased by 8.1 % for planting the seedlings with an intermediate row of 15 cm (compared to 45 cm row spacing) respectively, and the leaves weight was 13,7 % higher by the fruit formation time. The plants density in the area (intermediate row 15 cm) contributed to increase in individual fennel productivity (green mass of plants). The maximum yield of fennel seeds in the experimental sites was noted for the row spacing of 45 cm – 5.9 kg/10 m2. Thus, the most favorable conditions for fennel growth and development are under seedling planting on April 20, as the maximum yield is noted here. The denser placement of plants in the area (15 cm spacing) contributes to individual productivity increase (green plant weight, including leaves and stalks). Increasing the row width (up to 45 cm) contributed to the maximum yield of fennel seeds up to 5,9 kg/10 m2. Key words: fennel, seedlings planting terms, row width, productivity, leaf apparatus.
