Purpose. To reveal the peculiarities of the seasonal rhythm of growth and development of Itoh Group peony cultivars in the conditions of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine. Methods. The objects of research were plants of 24 cultivars of Itoh Group peonies. The research was conducted on the experimental field of the Department of Flowering and Ornamental Plants of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine during 2017–2020. The sum of effective temperatures was calculated by summing the daily air temperatures reduced by the biological zero.                 Results. The phenological phases of Ito Group cultivars growth were determined. Phenological spectra for different groups are presented. It was determined that the flowering of early cultivars: ‘First Arrival’, ‘Hillary’, ‘Julia Rose’, ‘Morning Lilac’, ‘Old Rose Dandy’, ‘Sonoma Apricot’ starts at the sum of effective temperatures ≥ 400 °С. The middle group hybrids bloom when the sum of temperatures reaches 450 °С. This group includes: ‘Bartzella’, ‘Callie’s Memory’, ‘Cora Louise’, ‘Lollipop’, ‘Scarlet Heaven’, ‘Sonoma Velvet Ruby’, ‘Yellow Dream’, ‘Yellow Emperor’, ‘Yellow Heaven’, ‘Yellow Waterlily’. Late flowering group includes: ‘Border Charm’, ‘Garden Treasure’, ‘Kopper Kettle’, ‘Pastel Splendor’, ‘Prairie Charm’, ‘Viking Full Moon’, ‘White Emperor’, ‘Yankee Doodle Dandy’; accumulation of effective temperatures above 500 °С is an essential requirement for their flowering. Conclusions. Itoh Group cultivars successfully pass all phases of seasonal development and manage to complete the growing season. Cultivars belong to the spring-summer-autumn-green phenorhythmotype. The onset of the corresponding phenological phases in peonies of the studied group of cultivars requires a certain sum of effective temperatures. Plant outgrowth begins on March 23 – April 2, when the sum of effective temperatures ranges from 20–40 °С. The flowering of varieties characterized as late spring, lasts 6–9 days ± 3–4 days, depending on the varietal characteristics and the year of cultivation. A rapid increase in the sum of effective temperatures up to 700 °C shortens the flowering phase by 4–5 days. An assortment of early (May 22–25 ± 2–3 days), medium (May 26–28 ± 3–5 days) and late-flowering (May 29–31 ± 4–6 days) cultivars has been selected, what ensures the continuity of peony flowering during two months.

Purpose. To define of phenological and morphological features of A. donax var. versicolor growth during the introduction in the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (NBG). Methods. The object of research was the plants of A. donax var. versicolor in the collection of ornamental grasses of the department of flower and ornamental plants of NBG. The plants were grown on a sunny experimental area during 2014–2020. Since under NBG conditions, A. donax var. versicolor did not enter the flowering phase, the beginning of the phases of spring regrowth, leaf unfolding, and the end of the growing season were recorded. Morphometric parameters and shoot-forming ability were investigated for 3–5 years of cultivation. Results. The beginning and duration of the phases of shoot spring regrowth and the unfolding of leaves of A. donax var. versicolor as well as their dependence on the sum of effective temperatures was established. Thus, spring regrowth begins with renewal buds on May 11 ± 5 days at the effective temperature sums of 226.6 ± 19.7 °С. The phase of leaf development in plants occurred on May 20 ± 7 days. The effective temperature sum at the beginning of this phase was 309.45 ± 11.66 °C. The productivity of shoot formation (1.6 ± 0.3 shoot per plant) under the conditions of introduction was determined. Conclusions. A. donax var. versicolor plants did not have a full cycle of seasonal development in the conditions of the NBG. Plants formed vegetative monocyclic shoots 240–260 cm tall. The duration of their vegetation was 182–189 days. The optimal period for the growth of the ground mass of plants fell on July-August. During this period, the leaves were quickly formed, the number of which was 28.8 ± 6.68 on the shoot. The correlation between the rate of accumulation of effective temperatures and the rate of regrowth of plant shoots was recorded.

The purpose of this work was to investigate ontomorphogenesis of Asphodeline lutea (L.) Rchb. (a rare Mediterranean species of plants for Ukraine) in culture, to analyze the features and describe plants in а different age stages and the sequence of their passage by individuals outside of the natural area in M.M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (Kyiv). In the article detailed morphological descriptions of plants in different age stages are given. The plants were studied in culture. Observations were conducted during 5 year period (2014-2019). The growth and development of individuals in this article are considered as components of ontogenetic changes in plants within a large life cycle. Ontomorphogenesis was studied by conventional methods. For the description of the ontogenetic development degree of individuals, the terms "age-stage" and "age-period" are used. To describe the variation of the passage by individuals of ontogeny stages we divided stages into ontomorphs, which determined the degree of development-degradation of plants. Due to the fact that A. lutea is included in the Red Book of Ukraine (2009), after research of the the specimens they were planted in the soil for further growth. It has been established that A. lutea plants go through four periods of ontomorphogenesis and eight age stages in culture. Plants annually bloom, form seeds and seedlings. As a result of observations of individuals, it has been established that A. lutea plants are drought-resistant and winter-stable in Kyiv, and their annual cycle of development depends on seasonal climatic variations. Asphodeline lutea is a perennial herb with a short rhizome and monocarpic generative shoots, vegetatively mobile. The underground part is a rhizome with renewal buds and stocking roots. Vegetative recovery occurs from underground buds. Pregenerative period lasts 5 years or more. Seedlings and juvenile plаnts are formed during one period of vegetation. Due to the degree of development of juvenile and immature plants they are divided into ontomorphotypes. Such differentiation determines the possibility of multivariate development in individuals. We noted that the virginіle plants can be represented as a separate shoots or а clone, that is formed as a result of "tillering". In the generative period a further vegetative growth is characteristic for A. lutea, which is successfully used for artificial vegetative reproduction of these plants in culture. Formation of subsenile and senile plants is a result of prolonged cultivation in one place or in stressful conditions. In the postgenerative period of ontogenesis for the preservation of plants in a culture, it is necessary to "rejuvenate" them by separating and planting members of clonе to a new place. Due to the biological characteristics of the species, the examination of plants for the study of the ontogenetic structure of cenopopulations is best carried out during flowering, as later on, an overland part of the juvenile species may already be absent, which will affect the assessment of the age range of the population.
