Blue honeysuckle (Lonicera caerulea var. kamtschatica Sevast.) is a valuable berry crop with a unique biochemical composition. It is rich in vitamins, minerals, and biologically active substances. Different species and cultivars of honeysuckle require different cultivation conditions in the field of accelerated reproduction in vitro. Taking into account the high clonal replication potential of the plant, we conducted research on the chelated-iron form’s influence on the micropropagation productivity of the blue honeysuckle “Lulia” cultivar at the multiplication, rooting, and subsequent acclimatization stages of microplants. In a preliminary study, five types of iron chelates were tested with carboxyl- and phosphorus-containing ligands: Fe(III)-EDTA, Fe(III)-DTPA, Fe(III)-EDDHA, Fe(III)-HEDP, and Fe(II)-HEDP. Each type of iron chelate was applied at four concentrations: standard, decreased by 2 times, and increased by 1.5 times and 2 times in the basic Murashige and Skoog (MS) nutrient medium. It was found that the blue honeysuckle “Lulia” had a selectivity to the type of iron chelate that was used. The nutrient-medium modifications with iron chelates, which caused the plant response, contributed to a significant improvement in the plant’s physiological status and increased its survival rate during the microplant’s acclimation to the nonsterile conditions stage. At the rooting stage, an increase in the rooting rate of up to 100% (Fe (III)-EDDHA), an increase in the number of shoots by 1.5–2 times, and an increase in the number of roots by 1.4–1.9 times were observed. The positive effect of the iron’s chelated forms was also observed at the acclimation stage. According to the results of the research, the most suitable iron forms for clonal micropropagation of blue honeysuckle were carboxyl-containing Fe(III)-EDDHA and phosphonate-containing Fe(II)-HEDP. Moreover, the effectiveness of both complexonates was confirmed in a wide concentration range: Fe(III)-EDDHA from (×1.0) to (×2.0), and Fe(II)-HEDP from (×0.5) up to (×1.5).

Relevance. The annual increase in the area under the eggplant culture in small farms and the individual sector is explained by high nutritional, dietary, taste, and also the multi-purpose use of fruits. For optimal growth and development, eggplant needs a high amount of active temperature, which greatly limits the cultivation of crops in many regions of Russia. However, the egg-plant growing area is expanded through the use of industrial and film unheated greenhouses. The development of technology elements for growing eggplant in film greenhouses is relevant, as it contributes to an increase in the area of farms.Materials and methods. The aim of the research was to substantiate the elements of the technology for growing eggplant in film unheated soil greenhouses. The studies were carried out in 2018-2019 at the base of the Educational and Scientific Production Center “Vegetable Experimental Station named after IN AND.

Лук-порей – одна из распространенных овощных культур в Европе. В России порей можно отнести в категорию малораспространенных, что связано с рядом проблем: более суровыми климатическими условиями в период массовой уборки позднеспелых сортов по отношению к европейским странам и нехваткой помещений для хранения продукции с регулируемыми условиями. Распространение этой культуры сдерживается из-за недостаточной информированности населения об ее ценных свойствах и возможностей применения в питании, а также из-за отсутствия прогрессивной технологии выращивания и хранения. Современная технология лука-порея требует значительных затрат ручного труда во время товарной доработки. Все перечисленные факторы затрудняют внедрение лука-порея в массовое производство. Цель работы – изучить влияние гнездового размещения растений на раннюю и общую урожайность. Исследования проводили в 2019–2020 годах на коллекционном участке кафедры овощеводства, территории УНПЦ «Овощная опытная станция имени В.И. Эдельштейна». В исследованиях использовали сорта Карантанский, Коламбус. Использовали для посадки рассаду возрастом 60 суток, все варианты высаживали одновременно. Погодные условия 2019–2020 годов на момент высадки рассады в открытый грунт были приблизительно равны среднемноголетним значениям. Способ размещения рендомизированный, повторность четырехкратная. Площадь опытной делянки 38 м2, схема посадки – 70×30 см. Для получения рассады семена высевали в первой декаде марта, рассаду высаживали в открытый грунт в первой-второй декаде мая, пучковую продукцию убирали во второй декаде июля, сбор урожая проводили в первой декаде октября. В период вегетации были проведены биометрические измерения и учет урожая. Приведены особенности развития растений лука-порея в зависимости от варианта опыта. Сорта Карантанский и Коламбус рекомендуются для получения мини-продукции лука-порея, используя вариант два растения в гнезде. Для получения максимальной товарной продукции у изучаемых сортов необходимо выращивать одно растение в гнезде. Leek is the one of the most common vegetable crop in Europe. In Russia, leek can be classified as less common, which is associated with such problems as: harsher climatic conditions during the period of mass harvesting of late-ripening varieties in relation to European countries and the lack of premises for storing products with controlled conditions. The spread of this crop is hindered due to insufficient population awareness of its valuable properties and nutritional applications, as well as the lack of advanced growing and storage technology. Modern leek technology requires significant manual labour during product refinement. All these factors make it difficult to introduce leeks into mass production. The purpose of the work is studying the effect of nesting of plants on the growth and formation of the crop. Research was carried out in 2019–2020 at the collection site of the department of vegetable growing, the territory of the Vegetable Experimental Station named after V.I. Edelstein. The research used varieties Karantansky, Colambus. Seedlings aged 60 days were using for planting, all variants were planted simultaneously in one day. Seedlings aged 60 days were used for planting, all variants were planted simultaneously on the same day. Weather conditions in 2019–2020 at the time of planting seedlings in the open ground were approximately equal to the long-term average values. The placement method is rendomized, with four-fold repetition. The area of the experimental plot is 38 m2, the planting scheme is 70×30 cm. Seeds were sown for seedlings in the first decade of March, seedlings were planted in the open ground in the first or second decade of may, bundle products were harvested in the second decade of July, and the total yield was in the first decade of October. Biometric measurements and crop records were performed during the growing season. Features of development of leek plants depending on the experiment variant are given. Thus, the varieties Karantansky and Columbus can be recommended for obtaining mini-products of leeks, using the option of two plants in the nest. To get the maximum marketable products in the studied varieties, it is necessary to grow one plant in the nest.
