The collection of the daffodils of Central Botanical Garden of the NAS of Belarus unites 413 varieties representing 10 garden groups. In order to select daffodils for industrial gardening, a method for comparative assessment of cultivars has been developed, which is presented in this article.The system is based on the evaluation of cultivars of flower-ornamental plants. Cultivars of daffodils are evaluated in stages. In the period of mass flowering, a 5-points scale is used to assess the decorativeness of cultivars and their adaptability to local conditions. For further study, prospective varieties are distinguished, estimated at no lower than 4 points. They are grouped by garden groups, by color and size of flowers, flowering time, height of peduncles and practical use (group planting, cutting, forcing). In the selected groups and subgroups, a comparative assessment of promising varieties is made by of decorative and economic-biological qualities.The decorativeness of the cultivars is proposed to be assessed on a 100-point scale in total by 8 features: color, flower size, heat resistance of the flower, the quality of the perianth stems, the quality of the peduncle, the duration of flowering, abundance of flowering, originality. Each attribute is evaluated on a 5-point scale and multiplied by the coefficient of its significance, respectively, the maximum score of the attributes ranges from 10 to 15 points.The assessment of the economic and biological qualities of cultivars is carried out in total within a 50-point scale in 7 indicators: winter hardiness, spring frost damage, resistance to disease, resistance to pests, resistance to viral infection, reproductive capacity, plant condition. Coefficient of significance of all signs 1–2.Assessment of cultivars of daffodils in total for decorative and economic-biological characteristics is a key moment in the formation of the assortment of daffodils for industrial use. It allows selection of the most decorative, stable and well-breeding varieties in local conditions, estimated at not less than 130 points.

Berry Ripening

<p style="text-align: justify;">Given the climat of the Bordeaux area, major climatic accidents can affect both the yield and the quality of the crop. Spring frost can destroy the future harvest, as happened in 1977 and 1991. Heavy rain in September can compromise a promising grape potential, evaluated at the end of August, and cause major <em>Botrytis</em> problems, as happened in 1963, 1965, 1968, and, more recently, in 1993. In this paper we discuss how soil and vine covering can contribute to avoid these problems. Vine covering, by means of a transparent plastic sheet, was experimented with in 1995 and 1996, between the end of March and early May, to reduce frost harm. In September of the same years, at the end of the ripening period, we studied the influence of soil covering (mentionned "BS") as well as soil and vine covering (mentionned as « BT ») on water status of the vines, microclimate, berry ripening and wine quality.</p><p style="text-align: justify;">In 1996, 14 p. cent of the buds were frozen in the control plot. No frost damage was noted underneath the plastic cover. In the same year, when most of our observations were made, supranormal rainfall in August preceeded the second period of soil and vine covering, carried out on 27th August. Under these conditions, we did not mesure any difference in vine water status until the harvest on the three plots. Microclimate was warmer and drier on the covered plots, especially underneath the over-vine cover.</p><p style="text-align: justify;">On the covered plots, yields were higher. In 1996, on BT, the vines carried more bunches, the bunches carried more berries and berry weight was higher. The control vines were significantly more affected by <em>Botrytis</em> compared to BS ; BT showed almost no rot. Berries on the covered plots showed a tendancy of having more sugar and total phenolics, and less malic acid. Separate microvinifications were done with 50 kg of grapes from each plot. Wine from BT was preferred over BS. Wine from the control plot was the least appreciated.</p>

Fruiting is an important characteristic of plant adaptation to new growing conditions. This is especially actual for ornamental plants, which, after successful introduction, can be used in landscaping of settlements. The genus Syringa L. has about 30 species, many of which can replenish the range of ornamental plants in the region. The collection of lilacs of the South Ural Botanical Garden-Institute of the UFIC RAS (Ufa Federal Research Centre of Russian Academy of Sciences) currently contains 11 species that have reached a generative state. The aim of this research is to identify the features of fruiting species of the genus Syringa during introduction in the conditions of the Bashkir Cis-Urals. The fruiting level of lilac species in the collection of the Botanical Garden was studied by determining the total number of fruits of the mother bushes. It is revealed that the fruiting level of introduced species of lilac is determined by the biological (hereditary) characteristics of the species and seasonal changes of weather conditions. S. velutina is characterized by the highest fruiting level, S. vulgaris and S. wolfii – by the lowest ones. It is assumed that there might be a tendency for dependence of the degree of fruiting on the quality of the formed pollen. Two taxa among all studied ones demonstrate fruiting level instability: S. reticulata ssp. reticulata blooms and bears fruit irregularly, while S. reticulata ssp. amurensis has regular abundant flowering, but there is a lack of fruiting in some years.

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 assortment of floral and ornamental plants is annually replenished with new varieties of perennial floral plants. The group of late summer and autumn flowering perennials is one of the most popular in landscaping. Korean chrysanthemum (Chrysanthemum сoreanum) is one of the most promising crops for landscaping settlements in the Republic of Belarus, therefore, breeders of the Central Botanical Garden of the National Academy of Sciences of Belarus began to work with this group of small-flowered chrysanthemums.The article describes the results of breeding work, the purpose of which was to create local highly decorative varieties for our climatic zone. The method of free cross-pollination and subsequent selection from the obtained hybrid seedlings of the most promising forms were used in the work. The most significant features in the selection were the following: flowering time, winter hardiness, resistance to diseases and pests, as well as good vegetative reproduction. As a result, 4 domestic varieties of Korean chrysanthemum have successfully passed state variety testing and have been registered in the National List since 2020. Descriptions of these new varieties, their biometric parameters, decorative parameters and flowering times are provided.

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.

Methods. Analysis and synthesis, comparison and generalization of information data, introduction forecast. Results. The modern assortment of the genus Salvia is presented in quantitative, taxonomic, arealogical and ecological-cenotic terms. Belonging of the species of the genus to 6 main centers of origin of cultivated plants was determined, and a significant diversity of life forms (nanophanerophytes, microphanerophytes, hamephites, hemicryptophytes, theophytes), naturally formed under the influence of factors determined by different geographical and ecological-phytocenotic conditions of plant growth was reflected. Species assortment of the genus Salvia from the collection fund of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine was analyzed in comparison with the collections of other Ukrainian botanical gardens. The list of decorative species of the collection, found in the natural flora of Ukraine, was given. Three groups of species have been identified by origin, what determines the conditions for plant cultivation in the Forest-Steppe of Ukraine. In terms of taxonomic structure, introduced sage species belong to eight (according to Bentham, 1833) out of twelve sections, which represent biomorphological diversity and confirm the high introduction potential of these plants.  The species and interspecific hybrids most fully used in breeding work and represented by a significant varietal diversity were distinguished, as well as the sage assortment of the collection of ornamental plants of the NBG was presented. Conclusions. It has been revealed that the species and varietal diversity of the genus Salvia of the world cultivated flora has a significant introduction potential for the Forest-Steppe zone of Ukraine. It was determined that the main base for the introduction of the ornamental species of the genus Salvia in Ukraine is the collection of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine. The main directions of further introduction and breeding work with representatives of the genus Salvia in the Forest-Steppe conditions of Ukraine were highlighted.
