“…The advantage of actinidia fruits is due to their high content of biologically active substances with antioxidant properties, vitamins, catechins, pectin, tannins and coloring substances, flavonoids, alkaloids and other compounds. The use of fruits of this culture provides the human body with a complex of biologically active compounds [18,19].…”

The unique collection samples of the Far Eastern species of the genus Actinidia Lindley preserved in Federal Horticultural Center for Breeding, Agrotechnology and Nursery were analysed. The in vitro collection of Actinidia has been formed since 2005 in Tsitsin Main Botanical Garden of Russian Academy of Sciences and currently includes more than 40 cultivars belonging to 3 species of Actinidia: A. kolomikta (Rupr. еt Maxim) Maxim., A. arguta (Siebold et Zucc.) Planch. et Miq., and A. polygama (Siebold et Zucc.) Maxim. Easily reproducible, dependable method for clonal micropropagation of promising selected genotypes of Actinidia was optimized. It has been established regeneration features for the studied species of the genus Actinidia at the stage of micropropagation. A. kolomikta was characterized by a lower morphogenetic potential (multiplication coefficient 5.0) compared with other studied species. A. arguta and A. polygama were characterized by high multiplication coefficients, but no significant difference between them was present (8.0 and 7.7, respectively). The features of morphogenesis of male and female forms of A. kolomikta were revealed. The cultivars of the female forms had the highest multiplication coefficient (‘Universitetskaya’ 5.2, ‘Prelestnaya’ 5.2) compared with the male and bisexual forms (‘Adam’ 4.3 and ‘Dr. Szymanowski’ 4.3). The Quorin-Lepoivre nutrient medium supplemented with 6-Benzylaminopurine at a concentration of 0.5…1.0 mg L−1 was found to be effective at the micropropagation stage, and the use of β-indole acetic acid at a concentration 0.5…1.0 mg L−1 was better at the rooting stage.

Among the representatives of the Actinidia Lindl. genus, Actinidia kolomikta (Siebold et Zucc.) Planch. is valued as the most winter-hardy variety with high taste and dietary properties. The Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery has a live collection of Actinidia, which includes more than a hundred cultivated forms and varieties. In this study, ash content in Actinidia kolomikta fruits of 10 varieties and collection samples was studied by energy-dispersive X-ray spectroscopy using an analytical scanning electron microscope JEOL JSM6090 LA. A decreasing series was established for the accumulation of ash elements in the fruits of the studied samples: Ca> K> P> Mg> Mo> S> Se> Zn> Fe> Co> Si> Na. In terms of accumulation of useful macro- and micronutrients, the most valuable varieties were identified. The total accumulation of macronutrients in the fruit ash ranged from 28.6 to 45.3 wt%. This indicator was the highest in the fruits of Dolgovechnaya, Uslada and Vinogradnaya (42.068–45.638 wt%). The fruits of the Uslada variety were distinguished by a high content of phosphorus (5.89), silicon (0.504), sulfur (1.34) and potassium (23.596 wt%). In terms of micronutrient accumulation, the Pamyati Kolbasinoj variety (4.904 wt%) showed the highest levels of molybdenum (3.804) and selenium (0.801 wt%). Iron accumulated more readily in the fruits of the Uslada variety (0.161), cobalt — in Nadezhda (0.157), zinc — in Vinogradnaya (0.247) and Chempion (0.195). A statistically significant positive correlation (r > 0.7) was revealed in the accumulation of the following pairs of ash elements: sodium — sulfur (r = 0.70), phosphorus — potassium (r = 0.75), silicon — iron (r = 0.76), as well as molybdenum with phosphorus (r = 0.84), sulfur (r = 0.83) and potassium (r = 0.71). A statistically significant negative correlation was observed only for the accumulation of phosphorus and calcium (r = -0.71). According to the results, the fruits of the Actinidia kolomikta varieties under study can be an additional or alternative source of dietary minerals in functional food products.

Реферат. Проблема распознавания пола у Actinidia Lindl. связана с отсутствием морфологических и анатомических маркеров пола у ювенильных растений, и до первого цветения сеянцев невозможно определить пол каждого растения. Исследование посвящено поиску различий физиолого-биохимических показателей мужских и женских растений многолетней двудомной культуры актинидии коломикта (Actinidia kolomikta) для ранней диагностики пола ее растений. Методом спектрофотометрии определено количественное содержание фотосинтетических пигментов и сумма фенольных соединений (с использованием реактива Фолина-Чокольтеу). Установлено, что в течение исследуемого периода количество хлорофилла a и b в коре мужского растения в 1,1-2 раза больше, чем в коре женского. Содержание хлорофилла a в 1,1-2,9 раза больше, чем хлорофилла b. Достоверные различия по содержанию суммы каротиноидов и сумме фенольных соединений в коре мужских и женских растений актинидии отсутствуют. Методом газовой хроматографии с массспектрометрическим детектированием исследован качественный и количественный состав метаболитов коры женской и мужской формы A. kolomikta. В экстрактах коры было определено 52 химических соединения различной природы: из них 18 органических кислот, 16 углеводов, 5 лактонов, 4 соединения фенольной природы, 5 соединений из группы органических спиртов, 3 соединения, относящихся к жирным кислотам, а также аукубин. В коре мужского растения актинидии содержится на 8 органических кислот больше, чем в коре женского. В результате проведенного сравнительного анализа установлено наличие в исследуемых образцах общих и специфичных вторичных метаболитов. Приведенные в работе различия качественного состава метаболомных профилей и количества фотосинтетических пигментов коры однолетних побегов мужских и женских растений могут быть использованы в дальнейшем как биологические маркеры для ранней диагностики пола у A. kolomikta.Ключевые слова: Actinidia kolomikta, кора, газовая хромато-масс-спектрометрия, хлорофилл, фенольные соединения, биохимический состав Summary. The problem of sex recognition in Actinidia Lindl. is associated with the lack of morphological and anatomical markers of sex in juvenile plants and it is impossible to determine the sex of each plant before the first flowering of seedlings. This study is devoted to the search for differences in the physiological and biochemical parameters of male and female plants of the perennial dioecious culture Actinidia kolomikta. The purpose of this study is to find differences in the physiological and biochemical parameters of male and female plants of the perennial dioecious culture A. kolomikta for early diagnosis of the sex of plants. The quantitative content of photosynthetic pigments and the sum of phenolic compounds (using Folin&Ciocalteu's phenol reagent) were determined by ФГБНУ ФНЦ СадоводстваСборник научных работ
