The genus Rubus is one of the largest taxonomically diverse and complex genera in the family Rosaceae. Morphology of pollen grains (equatorial and polar axes length, shape and size, aperture position, exine sculpture, perforations) is regarded as one of its main diagnostic features for identification of species and varieties. An attempt was made to fill the gap concerning the pollen micromorphology and ultrastructure of R. idaeus L. using light, scanning, and electron transmission microscopy. This study is a comparative analysis of micromorphological and ultrastructural traits of pollen from six raspberry cultivars. The pollen grains were classified as small or medium of shape prolato-spheroids. The parallel striae in the equatorial view in the exine sculpture were sometimes branched dichotomously in ‘Glen Ample’, ‘Polka’, and ‘Polana’, arcuate in ‘Laszka’ and ‘Pokusa’, or irregularly overlapping in ‘Radziejowa’. The width of exine striae of biennial fruiting cultivars was much larger than in repeated fruiting cultivars. In terms of the increasing number of perforations per unit area of the exine surface, the cultivars were ranked as follows: ‘Pokusa’ < ‘Glen Ample’ < ‘Laszka’ < ‘Polka’ < ‘Polana’ < ‘Radziejowa’. The thickest tectum, the highest and thickest columellae with the largest distances between them, and the thicker foot layer were demonstrated in ‘Glen Ample’. The ectoexine constituted on average ca. 78–90% of the exine thickness. The findings may constitute auxiliary traits i.a. for identification of related taxa, interpretation of phylogenetic relationships, and pollination biology.

“…They believe that plants become more mobile, they are isolated from the soil and are less susceptible to root infections. This is a big advantage for the profitability of growers [7]. However, when growing raspberry in containers, its lifespan reduces to two-three years.…”

When studying the world and domestic experience of cultivating primocane -fruiting raspberry varieties, the greenhouse crop cultivation method has attracted attention. Cisbaikalia is a territory where the cultivation period for horticultural crops is not long, whereas the need for fresh berries is high. Taking that into consideration, we see the prospect of developing a technology for cultivating primocane-fruiting raspberry varieties in the extended cycle in the Southern Cisbaikalia growing conditions. The present paper introduces the research carried out in 2019-2021 at the experimental site Phytotron of Siberian Institute of Plant Physiology and Biochemistry of the Siberian Branch of the Russian Academy of Sciences (Irkutsk, Russia). The research objects were varieties and selected forms of domestic primocane-fruiting raspberry. For this purpose, the plant productivity was determined, and phenological observations were performed. The research was carried out according to the generally accepted program and methodology for the variety study of fruit, berry and nut crops. The research involved medium and late-ripening varieties with a long fruiting period, such as Oranzhevoye chudo, Zhar ptitsa, Gerakl, Bryanskoye divo, Rubinovoye ozherel’ye, selected form 37-15-4. Plants of the first year of growth, which were in the budding phase at the time of transplantation, were selected. The plant preparing for transplantation was started 4 weeks before. In the first week of September, seedlings were transplanted into 8-10 liter containers. For normal growth and fruiting under new growing conditions, optimal water and temperature conditions were created, the plant feeding was improved. All the plants adapted well to the extended cultivation and entered the fruiting phase. High productivity was observed in Gerakl, Oranzhevoye chudo, and Rubinovoye ozherel’ye.

“…In these countries, the raspberry production system has changed, and cultivation with nutrient substrates, pots, and polytunnels are preferred over traditional cultivation. Such structures enable regulating microclimatic conditions and limiting the spread of diseases and pests (Marchi et al, 2019;Linnemannstöns, 2020;Tan et al, 2020).…”

The biochemical compounds of red raspberry (Rubus idaeus L.) fruits cultivated with conventional growing technology and on a nutrient substrate were studied during 2019–2020 at the Federal Horticultural Research Center for Breeding, Agrotechnology and Nursery, Moscow, Russia. The antioxidant activity, phenolic compounds, and ash constituents of the fruits and the metabolites of the alcoholic extract of the raspberries were determined. The effect of growing technologies, i.e., conventional vs. nutrient substrate, on the accumulation of macro- and microelements in raspberry fruits was established. In red raspberries grown on nutrient substrate, the antioxidant activity decreased by 25 times (aqueous extract) and 1.5 times (alcoholic extract). The K and Na contents and Se contents of red raspberries grown on nutrient substrate were 1.5 and 3 times higher than those of raspberries of grown with conventional technology. Raspberries grown with conventional technology contained 2 times more Ca, Ni, and Mn and 7.4 times more Fe than raspberries grown on nutrient substrate. The total amount of elements in raspberries grown through soilless cultivation was 5.5% higher than that in berries grown conventionally. A total of 48 compounds were identified in the alcoholic extracts, and only 29 substances were found in berries grown on a nutrient substrate. Sugar and citric acid constituted the largest share of red raspberry components. Fructose and turanose disaccharide synthesis in raspberries grown on nutrient substrate was 20% higher than that in conventionally grown raspberries. A total of 48 organic compounds with different biological activities were identified. They included five substances with antimicrobial activity, three phenolic substances, eight organic acids, four sugar acids, nine amino acids, and 19 sugars and their derivatives. At the same time, 42 compounds were found in raspberries grown with traditional technology, and 21 compounds were identified in raspberry fruits grown on nutrient substrate. Three fatty acids, namely, ɑ-linoleic acid (polyunsaturated omega-6 fatty acid), palmitic acid, and stearic acid (saturated fatty acid), along with cinnamic acid, shikimic acid, and chrysin were found in berries grown conventionally.
