Plants of the genus Chaenomeles are traditionally used in the countries of South-East Asia, due to their high nutritional and health-promoting properties. However, the successful introduction of species promising for gardening from geographically remote areas requires the study of plant ontogeny under the conditions of new habitat. This is a very substantial problem for the steppe zone, where the continental climate has features of aridity and complicates the process of increasing the diversity of fruit crops by introducing the desired species. The present study aims to assess the effectiveness of the protective enzymatic system of different Chaenomeles genotypes subject to a steppe climate as well as the accumulation of the biologically active compounds with high antioxidant capacity. The study was performed on the basis of the introduced horticultural plants collection in the Botanical Garden of the DNU, and the Chaenomeles fruits, leaves, and the seeds were examined. The highest activity of catalase, benzidine-peroxidase and guaiacol-peroxidase, and the greatest enzymes activation during vegetation were found in leaves of Ch. cathayensis and Ch. speciosa, while the lowest activity was in leaves of both Japanese species. The biggest total phenolic content in the isopropanolic plant extracts, determined by Folin–Ciocalteau assay, was found in leaves of Ch. × superba, Ch. × californica and Ch. cathayensis (44.8, 52.8, and 43.6 mg GAE/g WW); a less high level was found in leaves of Ch. japonica and Ch. japonica var. maulei (43.1 and 40.2 mg GAE/g), while the lowest was in leaves of Ch. speciosa (29.3 mg GAE/g). The total flavonoids content determined using the aluminum chloride method, did not differ by variety or species in the plant leaves, being in the range of 2.6–2.9 mg of RE per g WW (accordingly, in leaves of Ch. japonica var. maulei and Ch. × californica). The high total reducing power determined by potassium ferricyanide assay was found in leaves of both hybridogenic species and Ch. cathayensis (respectively, 11.6, 14.1, and 11.4 AAE/g WW); leaves of both Japanese species had slightly lower values and the lowest was in leaves of Ch. speciosa (7.7 AAE/g). In the Chaenomeles fruits, the total phenolic content was the lowest in Ch. speciosa (17.8 mg GAE/g), average in both Japanese species (28.7 and 27.8 mg GAE/g), and the highest (33.3 mg GAE/g) was in Ch. cathayensis. The flavonoid accumulation was highest in the fruits of Ch. cathayensis and Ch. japonica var. maulei (0.67 and 0.63 mg RE/g), intermediate in both hybridogenic species and Ch. japonica (accordingly, 0.57, 0.42 and 0.38 mg RE/g), and the lowest in Ch. speciosa (0.30 mg RE/g). The total reducing power of Chaenomeles fruit was lower as compared to leaves, and decreased from 11.2 to 5.7 mg AAE/g in the series Ch. cathayensis > Ch. × californica > Ch. japonica > Ch. japonica var. maulei > Ch. × superba > Ch. speciosa. High correlation coefficients between total reducing power and total phenols content in the Chaenomeles leaves and fruits (respectively, r = 0.96 and r = 0.95, P < 0.05) confirm the significant contribution of phenolic compounds to the antioxidant capacity. The study results indicate a high antioxidant capacity of the Chaenomeles species in the conditions of the steppe climate due to the antioxidant enzymes activity and the accumulation of a significant amount of phenolic metabolites in leaves and fruits.

“…In the steppe zone of Ukraine, maintaining the existing plant diversity and expanding its spectrum can be effective if species are introduced from other geographical areas. Particular attention is paid to fruit plants, a significant group of which are non-traditional fruit crops (Khromykh et al, 2018a;, which are characterized by rapid growth, durability, annual abundant fruiting, high taste and therapeutic and dietary qualities of fruits. In addition, they have decorative, phytomeliorative, honey and medicinal properties (Andola et al, 2010).…”

“…To date, more than 400 species of fruit and berry plants have been introduced in different regions of Ukraine (Klimenko et al, 2013; Shcherbyna et al, 2017), but the number of species introduced into industrial steppe zone gardening is insufficient. Plant species and hybrids originating from arid or mountainous habitats and having a high adaptive capacity to the steppe climate, including species of the genera Chaenomeles Ukrainian Journal of Ecology, 9(4), 2019 L. and Berberis L., may be promising for the region's introduction (Khromykh et al, 2018a(Khromykh et al, , 2018b. The fruits of these plants have high nutritional value and are a source of physiologically active compounds, which has led to their centuries-old use in traditional medicine, and today puts in a number of important objects of numerical research in order to obtain raw materials for the creation of functional products and medicines.…”

“…In the steppe zone of Ukraine, the introduction of plants from remote geographical areas, including natural and hybrid species of the genera Berberis L., has been taking place at the Botanical Garden of Oles Honchar Dnipro National University (city of Dnipro) for many years (Figure 1). The study of phenolic compounds content in the fruits of introduced barberry plants revealed the dependence of their accumulation both on the species properties of the plants and on environmental conditions (Khromykh et al, 2018a). Generally, the content of physiologically active substances in fruits and other parts of plants has been shown to be genetically determined and at the same time have a high dependence on the microclimatic and edaphic conditions under which the ontogenetic development of fruit plants occurred.…”

The study dealt with the patterns of adaptation of the genus Berberis L. low-abundant alien plants to the climatic conditions of the steppe zone of Ukraine. The success of the introduction, which was conducted on the territory of the Botanical Garden of Oles Honchar Dnipro National University (city of Dnipro) near 60 years ago, was evaluated by a set of indicators. According to the study of phenological rhythms, introduced plants can be characterized as plants with a relatively short growing season, a relatively long shoot growth, a short flowering period and a long maturing period. This indicates the lability of the phenological rhythms of the introduced plants, which respond to changes in environmental conditions in terms of the beginning and end of the phenological phases. The aquatic regime of introduced plants reflects the level of their adaptation to the environment due to the ability of plant organism to withstand water consumption. The study of water exchange features of Berberis L. plants revealed a moderate decrease in the intensity of transpiration and a moderate water deficit in the plant leaves, which indicates the adaptation of the species to the difficult climatic conditions of the steppe zone. The response of introduced plants to the level of moisture in the steppe region confirmed the universal mechanism of plant adaptation to arid conditions. Comparative analysis of the reproductive ability of introduced plants of the genus Berberis L. in the conditions of the Botanical Garden revealed a significant variability of quantitative indicators. The weight of 100 fruits ranged from 12.5 g (B. vulgaris) to 16.3 g (B. declinata). Seed length varied from 4.5 mm (B. canadensis) to 5.2 mm (B. declinata, B. amurensis), seed width varied from 1.8 mm (B. amurensis, B. vulgaris) to 2.1 mm (B. koreana). The highest mass of 1000 seeds was observed in the species B. koreana. To compare sample averages, the criterion for the significant difference of Tukey's group averages was used. The investigated plants of the genus Berberis L. can be recommended for the introduction into large-scale and individual gardening in order to expand the range of fruit products and obtain biologically valuable raw materials for the industrial production of functional products.

In recent years, interest in cultivating Ginkgo biloba L. as a medicinal plant has grown in Ukraine, and improvement of the technology of growing this plant in the conditions of the North-East of Ukraine is a relevant problem. The purpose of this article to present research on the morphological structure, growth and viability of young G. biloba plants in grown from seeds by different technologies and comparative analysis of growth and development of G. biloba plants under greenhouse conditions and on open soil. The experiment on G. biloba cultivation was initiated in 2014 in three variants (the plants were grown from the seeds). Variant No 1: G. biloba growing in a greenhouse at 60–80% humidity and temperatures not below +27 ºС; shading (shading level 60%) by green agronetting. Variant No 2: growing in open soil; shading (shading level 60%) by green agronetting; the climatic conditions were typical for Sumy region. Variant No 3: growing in open soil; there was no shading; climatic conditions were typical for the Sumy region. Plant analysis was conducted in June 2018. The following morphometric parameters of G. biloba plants were measured: plant height, annual growth of shoots, number of leaves, leaf size and leaf area, phytomass of the shoots, phytomass of leaves and phytomass of the stem, diameter of the shoots. The sampling used 60 samples. The leaf area was determined by the method of drawing contours on millimeter paper. Statistical processing of research results was carried out by generally accepted modern methods of mathematical statistics using dispersion, correlation, regression and vital analysis. In the conditions of the Ukrainian North East, G. biloba seedlings can be grown successfully in greenhouses and open soil, both with 60% shade by agronetting and without it. Differences between the plants grown in such conditions are insignificant and statistically unreliable. The obtained three to four year old G. biloba seedlings grown using different technologies were 25–30 cm in height and formed 13–17 leaves per plant. The seedlings were of quite high viability (Q is 0.22–0.30) and morphostructural integrity (67.8%). The output of viable seedlings (vital classes “a” and “b”) in variant 1 was 60%, variant 2 45% and variant 3 60%. Ecological-cenotic stability of G. biloba was observed repeatedly, though certain limitations on G. biloba cultivation may be that the plant is photophilic and thermophilic. But the conducted experiments show that the climatic conditions of the Ukrainian North-East are quite favourable for this species. Based on the data obtained for the Ukrainian North-East, it is possible to recommend the technology of growing G. biloba seedlings in open soil without agronetting as quite effective and low-cost.
