A review of the available literature data of some authors on the medicinal value of plants of the genera Elaeagnus and Shepherdia (Sehepherdia) of the Elaeagnaceae family is carried out to identify the current state and degree of knowledge of this theme, as well as to systematize this information. The article discusses the properties and medical uses of such species as Elaeagnus angustifolia, Elaeagnus argentea, Elaeagnus multiflora and Shepherdia argentea. Parts of these plants used in medical practice, their chemical composition, useful characteristics, and diseases, in the treatment of which it is reasonable to use medicines obtained from the plants which are being studied, are described. Then are given existing medicines obtained from the considered species, their characteristics and application are discribed. Also article includes the basics of cultural practice of Elaeagnus and shepherdia. Species of the Elaeagnaceae family are very valuable for world medicine.
Sea buckthorn is often perceived and used precisely as a fruit crop, but it also has decorative qualities. When choosing varieties for gardening, it is important to know the phenological dates of the onset of decorative phases, but literary sources often indicate only one phenophase - the period of fruit ripening. The purpose of this work is to analyze 18 varieties of sea buckthorn of the average ripening period according to the degree of originality of the onset of a number of phenophases. Female sea buckthorn plants are in the collection of the Main Botanical Garden. N.V. Tsitsina (Moscow, Russia). Annually from 2014 to 2019, 16 phenodates were noted (swelling and blooming of buds, appearance and blooming of leaves, complete leafing, yellowing of leaves, leaf fall, beginning of budding, mass budding, beginning of flowering, mass and end of flowering, fruit setting, single ripening, mass ripening , fruit fall). Originality coefficients were calculated by a statistical method for assessing the modality weight. It was found that among the varieties of the average ripening period, the Chuiskaya and Gus-Khrustalnaya varieties have a high degree of originality of the complex of phenological dates, and the overwhelming majority of varieties are the most typical in the sample.

In this work, the results of evaluating the differences in the variants of the three-factor experiment on rooting of varieties of Barberry Thunberg (Berberis thunbergii DC.) By factors: varietal characteristics, the number of nodes and the use of a root formation regulator are considered. The study involved cuttings of the following varieties: ‘Dart’s Red Lädy’, ‘Kobold’, ‘Golden Ring’, ‘Harlequin’, ‘Rosetta’, ‘Red Chief’ and ‘Aurea’. 4- (indol-3-yl) butyric acid (trademark "Kornevin") was used as a root formation stimulator by the method of dusting. The green cuttings had 2 and 3 knots. The results of analysis of variance on the variability of the average total root length in green cuttings depending on varietal characteristics, dusting with a root formation stimulator and the number of nodes made it possible to establish that the ‘Red Chief’ variety had the maximum average total root length and was significantly different from all other varieties. The average total length of roots when using a root formation stimulator is significantly higher than in the control variant. Cuttings with three nodes reliably had a large average total root length. Based on the results obtained, it is assumed that the use of a root formation stimulator and rooting of cuttings with three nodes has a positive effect on the rooting processes of barberry cuttings. Keywords: BERBERIS THUNBERGII, THUNBERG BARBERRY, GREEN CUTTINGS, 4- (INDOL-3-YL) BUTYRIC ACID, KORNEVIN, KNOTS
The Sedum L. genus is extensively represented in the Tolstiaceae family, (more than 600 species). Diversity in the market of species makes genus Sedums popular and promising in landscape gardening, urban and interior gardening. In indoor floriculture, there are more than 20 species of sedums, which are herbaceous, succulent semi-shrubs that can be either single or perennials. Decorative effect is given to the plant primarily by decorative leaves, their structure and coloring. Sedum are in demand in modern interior landscaping.
