... Instead, BD and SM values are different in the two afforestation sites, but these differences are not related to the presence of the trees planted or the tree density used. Regarding AN, AK, and AP, the effect of trees on the soil concentration of these minerals did not provide a clear pattern despite it is known that H. rhamnoides is characterized by high nitrogen storage capacity (Zhou et al. 2017;Li and Schroeder 1996). Previous studies have reported that during the restoration of degraded farmland, the content of AN is characterized by a negative relationship with soil BD (Wang et al. 2011;Singh et al. 2012). ...
This work examines the variation of carbon sequestration (considered as the sum of above- and below-ground plant biomass production added to soil organic carbon) occurring in two sites (named respectively BN and ER) characterized by a semi-arid climate after planting three tree species (Populus sibirica, Ulmus pumila, and Hippophae rhamnoides). Soil organic carbon (SOC) was analyzed at four different depths (from 0–60 cm). In these two sites, the three tree species contributed differently to carbon sequestration. We found that above-ground plant biomass (leaf, branch, stem) was higher at the BN site whereas at the ER site prevailed below-ground biomass. That is probably due to the low tree density in BN site and the higher soil moisture content present in ER site. Among the three tree species considered, P. sibirica showed the highest biomass value. The SOC values were highest in the topsoil layer (0-40 cm) and decreased with depth. This works clearly shows that in semi-arid lands carbon sequestration depends on the environmental factors that characterize the site, the tree density, and the tree species selected.
... Hippophae rhamnoides L, a cold-resistant deciduous shrub, is an excellent soil and water conservation tree species, with yellow or orange berries, distributed in Asia and Europe [1] . Hippophae rhamnoides fruit has high nutritional value [2] and medicinal value [3] , however, because the Hippophae rhamnoides fruit is small and does not easily form a separate layer, the fruit is closely clustered on the branches covered with thorns [4] . Seabuckthorn fruit skin is thin and contains much water, so it is difficult to harvest directly. ...
Hippophae rhamnoides have yellow or orange berries, which have high nutritional and medicinal value, but it is difficult to harvest directly because of their close attachment to the fruit branches. The vibration harvesting equipment can be designed and developed correctly and reasonably by using the finite element method to study the vibration harvesting dynamics of Hippophae rhamnoides pruning and the parameter design of the related mechanism. First, the 3D model of Hippophae rhamnoides pruning was established by CATIA and was imported into ABAQUS software for modal analysis and harmonic response. The first 12 natural frequencies were determined to be 4.1 ~ 23.1 Hz, the optimum excitation frequency is 21.1 Hz and 16.2 Hz, and the optimum excitation force is 35 N and 25 N respectively. Secondly, the dynamic model of the cutting branch device is established and solved, and after bringing in the relevant parameters, the optimal design dimensions of crank r and connecting rod l are determined to be r1=22mm, l1=88mm, r2=13mm, l2=52mm, respectively. This research can provide a theoretical basis for the development and testing of a vibrating sea buckthorn-cutting harvesting device.
... It contains linoleic and linolenic acids, carotenes, fatty acids (primarily omega-3, omega-6, omega-9, and palmitoleic acids), and stearic acids. This is a multipurpose plant, the fruits of which are classified as "superfoods" [159][160][161]. The ability to enter into symbiosis with nitrogenfixing bacteria and resistance to adverse environmental conditions (drought, high and low temperatures, etc.) makes sea buckthorn a promising crop for growing in poor and polluted soils, as well as for land remediation. ...
... However, the maximum effective sex ratio differs depending on the plant and the type of pollination (insect pollination or wind pollination). For example, sea buckthorn shows the best yield in a planting pattern where one mixed row of male and female plants falls between two rows of female plants (in a mixed row, male plants comprise one in five plants) [160]. The role of the pollinator in the formation of economically valuable traits cannot be directly assessed. ...
Unlike in animals, dioecy among flowering plants is a rare phenomenon. The vast majority of angiosperm species have a bisexual flower that combines male (androecium) and female (gynoecium) reproductive organs. However, about a quarter of species have dioecious flowers, which can be located within the same plant (monoecious) or on different plants (dioecious). The flower formation in dioecious plants is determined by various genetic mechanisms. They become more complex from the work of a single gene to the functioning of full-fledged heteromorphic sex chromosomes, which can directly affect sex differentiation or participate in the balance determination of sex (where the formation of male or female flower organs depends on the ratio of X chromosomes to autosomes, for example). In recent years, the development of sequencing techniques, bioinformatics, and molecular biology has led to an increase in interest in the sex determination mechanisms among plants. It is noteworthy that a significant number of dioecious plants have economic value. At the same time, dioeciousness often complicates the growing process. This fact increases the relevance of studies on dioecious crops. In this review, we attempt to summarize the current information on sex chromosomes and the mechanisms of sex determination in dioecious plants, concentrating on species with agricultural importance.
... Due to its excellent medicinal and nutritional properties, sea buckthorn is widely used to treat and prevent Alzheimer's disease (1), cardiovascular disease (2), gastric ulcers (3), cancer (4), and skin problems (5). These applications of sea buckthorn are related to the rich active biological substances that are present in its berries, such as flavonoids (6), polysaccharides (7), polyphenols (8), organic acids (9), vitamins (10), amino acids (11), and other active substances (12). Although sea buckthorn berries are nutritious, their taste is sour and astringent, thereby rendering the plant unpleasant to eat raw. ...
Sea buckthorn ( Hippophae rhamnoides L.) is an edible and medicinal plant species. However, due to its sour taste, it is not readily accepted by consumers. To overcome this, fermentation can be used to change its flavor profile. In this study, we used response surface methodology (RSM) to determine the best process for producing fermented sea buckthorn juice (FSBJ) using probiotics. The biological enzyme activity and total flavonoid content (TFC) of sea buckthorn juice (SBJ) increased after fermentation. When the number of bacteria inoculated was 4.08 × 10 ⁶ CFU/mL and the inoculation ratio was 30% Z. mobilis , 5% L. casei , 13.75% L. plantarum , 31.25% P. acidilactici , 12.5% L. animalis , and 7.5% P. pentosaceus , the amount of sugar was 2.98% (w/v) after 20 h of fermentation at 37°C, and the superoxide dismutase (SOD) activity reached 725.44 U/mL, and the TFC reached 2.38 mg/mL. FSBJ demonstrated strong antimicrobial activity against Escherichia coli , Staphylococcus aureus and Botrytis cinerea . Then, to investigate the antioxidant capacity of FSBJ, we used H 2 O 2 to induce oxidative stress in C2C12 cells and assessed the protection conferred by FSBJ to damaged cells. It was discovered that after 24 h of treatment with FSBJ, not only was there an increase in the activities of intracellular SOD and glutathione peroxidase (GSH-Px), but also a reduction in reactive oxygen species (ROS) content, catalase (CAT) activity, and malondialdehyde (MDA) content. This research lays the theoretical groundwork and provides reference materials for the improved fermentation of sea buckthorn and demonstrates its resulting antioxidant effect.
... The constantly present H. rhamnoides belongs to the group of heliophytes, which prefers dry sites rich in Ca 2+ and is eminently light-demanding forming the highest level of vegetation (Kobendzina, 1969;Tobolski, 2003). Dunes were the proper habitat for Hippophae because this species can grow even on nondurable dunes and on irrigated soils due to its extensive root system (Li and Schroeder, 1996). The peatland was overgrown with B. nana, while its shores were occupied by Salix undiff. ...
This study investigated the history of the development of six, paleo-lakes, which are at present
filled with sediments, in a dune area in Central Poland, based on multiproxy paleoecological analyses and
accelerator mass spectrometry radiocarbon dating. The aims of the paleoecological studies were: i) to determine
the initial age of lakes development, ii) to reconstruct the local and regional plant succession, as well as iii) to
reconstruct the environmental conditions during the initial stage of the development of lakes and peatlands.
The obtained results indicated that: the former lakes in dune depressions were developed during the Bølling
and Allerød when sparse vegetation allowed strong aeolian activity. Climate warming in Bølling led to the
development of a denser plant cover, inhibition of sand transportation and the formation of mid-dune reservoirs
with the accumulation of organic sediments. As indicated by 14 C dating, mid-dunes basins were formed between
14 686 ± 60 cal. yr BP and 13 421 ± 60 cal. yr BP.
The results of the paleobotanical analysis suggested that the reservoirs were shallow, oligo-mesotrophic,
inhabited by pioneer calcicole vascular plant species such as: Chara sp., Hippuris vulgaris , Potamogeton natans ,
Potamogeton fresii , Potamogeton alpinus and Potamogeton filiformis , and mosses such as: Pseudocalliergon trifarium ,
Calliergon sp. and Calliergonella cordifolium . The area next to the reservoirs was covered with sparse
pine forests combined with birch, which is typical of the Late Glacial period. The open areas were dominated by
psammophilic and steppe vegetation, including Poaceae, Artemisia and Hippophae rhamnoides .
Geochemical analysis revealed that Ca 2+ and Fe 3+ were in high concentrations, which could have influenced
the presence of taxa preferring soil with high Ca 2+ content. The accumulation of calcium in sediments confirms
that the reservoirs were fed by groundwater originating from the progressive degradation of permafrost associated
with thermal changes.
... In its wild state, the sea buckthorn has been recognized for millennia as a plant with health benefits in different parts of the world -in Europe, by the ancient Greeks, and in Asia, in early Chinese Pharmacopeia and ayurvedic medicine (Suryakumar & Gupta, 2011;Wani et al., 2016). In the last decades, sea buckthorn started to be domesticated (Li & Schroeder, 1996) Biotechnologies, Vol. XXVI, No. 2, 2022ISSN 2285-1364, CD-ROM ISSN 2285-5521, ISSN Online 2285-1372, ISSN-L 2285-1364 ssp. ...
... Organic farming has been proved to increase the polyphenols and flavonoids content on sea buckthorn leaves (Heinäaho et al., 2006) and fruits (Heinaaho et al., 2009). Sea buckthorn is an appropriate plant to be cultivated in organic farming because of its microbial symbioses with nitrogen-fixing actinobacteria and mycorrhizal (AM) fungi (Li et al., 1996;Tian et al., 2002). These symbioses significantly support fertilization and plant protection organic management. ...
This paper reviews the present knowledge regarding the stimulation of the microbial symbioses of the sea buckthorn (Elaeagnus rhamnoides syn. Hippophae rhamnoides). Sea buckthorn is an actinorhizal plant, developing nitrogen-fixing symbioses with the actinobacteria from the Frankia genus. At the same time, sea buckthorn roots can form endomycorrhizal symbioses with various arbuscular mycorrhizal (AM) fungi. AM symbiosis increases nutrient uptake and nutrient use efficiency, especially on phosphorus and micro-elements. Due to these microbial symbioses, sea buckthorn is an efficient colonizer of marginal lands and a suitable crop for low-inputs organic/ecological farming. Helper bacterial strains were demonstrated to promote microbial symbiosis between Frankia actinobacteria or AM fungi with roots of other host plants. Only scarce and indirect information suggests the involvement of gram-positive, endospore-forming bacteria as a helper of microbial symbiosis for sea buckthorn. Also, there is no information regarding the role of rhizosphere signals in promoting the sea buckthorn microbial symbioses. The finding of this paper highlights the need for future works focused on the stimulation of sea buckthorn symbioses.
... The next step is vibration-assisted separation of the berries [18,19]. The cultivation of sea buckthorn is also actively used to control soil erosion and combat desertification [20]. As plantings grow, pruning of trees is carried out. ...
Plants growing in unfavorable environments, such as sea buckthorn, can have a high serotonin content. The potential of using different parts of sea buckthorn (Hippophae rhamnoides L.) as a natural source of serotonin was investigated. The feasibility of extracting serotonin hormone from the non-fruit parts of sea buckthorn is demonstrated. One- and two-year-old woody shoots were the best material for obtaining serotonin-containing raw product. Serotonin content in shoots of different sea buckthorn varieties growing in different regions and its dynamics during the vegetation period were determined by high-performance liquid chromatography. Serotonin is a water-soluble substance prone to microbial degradation, so proper preparation of raw materials plays a very important role in preserving serotonin in plant samples. A method for serotonin extraction using preliminary mechanochemical treatment is presented: it consists in pre-grinding, followed by mechanical treatment of raw materials with 5% adipic acid in a semi-industrial centrifugal mill. The highest degree of serotonin extraction was achieved when using air circulation at a drying temperature of 60–80 °C; serotonin concentration decreased when temperature was further increased. Serotonin content depended on the place and time of harvesting, the method used for drying the branches, and the characteristics of the plant variety. The minimum serotonin concentration (29 mg/g dry basis) was observed during summer; the maximum concentration was observed during winter; the annual changes in concentration can be as significant as 10-fold. The possibility of industrial cultivation and harvesting of different sea buckthorn varieties was also considered.

... The plant is well-known for its high content in vitamins (A, B1, B12, C, E and K) and flavonoids, and also minerals (Ca, Mg, K, Se, Na, Fe, Zn, P, Co, Cu, Cr, Ni, Mn, Li etc.), essential fatty acids, free aminoacids etc. It also possesses a strong antioxidant effect, thus having major therapeutic importance by inhibiting the free radical production and potentiates the production of intracellular antioxidants, such as GSH and GPx (Li and Schroeder, 1996;Patel et al., 2012). Sea buckthorn has multiple uses in traditional medicine (Wani et al., 2016). ...
Low-input farming subject’s swine to increased immune stress and subsequent infectious risk, which could be prevented by phytotherapy. Hypopphae rhamnoides is a widespread shrub in both Europe and Asia. The research aimed at investigating the influence of a whole fruit extract on antibacterial effect of the serum in extensively raised, two batches, sea buckthorn in vivo treated/untreated pigs. Scavenging effect over DPPH was used to estimate the antioxidant potential of the sea buckthorn commercial syrup (Steaua Divina©). Minimal inhibiting (MIC) and minimal bactericidal (MBC) capacity of the serum were tested and spectrophotometrically measured against Shigella spp., Kitococcus sedentarius, Staphylococcus werneri and Staphylococcus sciuri. The antioxidant activity of the syrup was intermediate (54.65 %). Sera from treated pigs had bactericidal and bacteriostatic effect on Shigella spp. and S. sciuri, respectively. Shigella spp. growth was inhibited at serum dilutions of ½-1/32 while much lower ½-1/4 dilutions were active against S. sciuri. In untreated pigs, the sera were inefficient in either stopping or totally inhibiting bacterial growth. The MBC and MIC values obtained for the sera of pigs treated with Hippophae rhamnoides syrup supported the positive effect of the in vivo treatment inducive of potential protection against bacterial diseases.
... It is an ideal plant for soil erosion control, land recovery, wildlife habitat enhancement, and farmstead protection. SBT has attracted considerable attention from researchers, producers, and various industries because it has a high nutritional and medicinal value for humans [5]. SBT is not a native plant to Latvia, although fossil pollen records indicate its presence in postglacial raw soils in this region. ...
The agricultural importance of sea buckthorn (SBT; Hippophae rhamnoides L.) is rapidly increasing. Several bacterial and fungal pathogens infecting SBT have been identified and characterized; however, the viral pathogens are not yet known. In this study, we identified, isolated, and sequenced a virus from a wild plantation of SBT for the first time. Sequence analysis of the obtained viral genome revealed high similarity with several viruses belonging to the genus Marafivirus. The genome of the new virus is 6989 nucleotides (nt) in length according to 5′, 3′ RACE (without polyA-tail), with 5′ and 3′ 133 and 109 nt long untranslated regions, respectively. The viral genome encoded two open reading frames (ORFs). ORF1 encoded a polyprotein of 1954 amino acids with the characteristic marafivirus non-structural protein domains—methyltransferase, Salyut domain, papain-like cysteine protease, helicase, and RNA-dependent RNA polymerase. ORF1 was separated from ORF2 by 6 nt, encoding the coat protein (CP) with typical signatures of minor and major forms. Both CP forms were cloned and expressed in a bacterial expression system. Only the major CP was able to self-assemble into 30 nm virus-like particles that resembled the native virus, thus demonstrating that minor CP is not essential for virion assembly.
... Hippophae rhamnoides bears yellow or orange berries, which are found as a powdered mix in food markets as a functional food and are used to manufacture fruit sauce and wine [24]. Vitamin C is the main nutritional component of H. rhamnoides fruits, the level of which surpasses that of lemons and oranges [25]. Previous studies on H. rhamnoides berries have reported that its extracts exhibit various therapeutic properties, including antiplatelet effects via the inhibitory mechanism of thrombin-activated platelets and antimicrobial effects through the inhibition of adhesion and biofilm formation of S. aureus and C. albicans [26,27]. ...
The fruit of Hippophae rhamnoides has been widely used for medicinal purposes because of its anti-inflammatory, antioxidant, antiplatelet, and antimicrobial effects. Since there are no clear reports on the therapeutic efficacy of H. rhamnoides in osteoporosis, this study aimed to confirm the potential use of H. rhamnoides for the treatment of osteoporosis through its osteogenic differentiation-promoting effect in ovariectomized mice. Through an in vitro study, we compared the effects of the EtOH extract of H. rhamnoides fruits (EHRF) on the differentiation of C3H10T1/2, a mouse mesenchymal stem cell line, into osteoblasts based on alkaline phosphatase (ALP) staining and the relative expression of osteogenesis-related mRNAs. The EHRF significantly stimulated the differentiation of mesenchymal stem cells into osteoblasts and showed 7.5 times (* p < 0.05) higher osteogenesis than in the untreated control. A solvent fractionation process of EHRF showed that the hexane-soluble fraction (HRH) showed 10.4 times (** p < 0.01) higher osteogenesis than in the untreated control. Among the subfractions derived from the active HRH by preparative HPLC fractionation, HRHF4 showed 7.5 times (* p < 0.05) higher osteogenesis than in the untreated naïve cells, and HRH and HRHF4 fractions showed 22.6 times (*** p < 0.001) stronger osteogenesis activity than in the negative control. Osteoporosis was induced by excision of both ovaries in 9-week-old female ICR mice for in vivo analysis, and two active fractions, HRH and HRHF4, were administered orally for three months. During the oral administration period, body weight was measured weekly, and bone mineral density (BMD) and body fat density were measured simultaneously using a DEXA machine once a month. In particular, during the in vivo study, the average BMD of the ovariectomized group decreased by 0.0009 g/cm2, whereas the average BMD of the HRH intake group increased by 0.0033 g/cm2 (* p < 0.05) and that of the HRHF4 intake group increased by 0.0059 g/cm2 (** p < 0.01). The HRH and HRHF4 intake groups significantly recovered the mRNA and protein expression of osteogenic genes, including ALP, Osteopontin, Runx2, and Osterix, in the osteoporosis mouse tibia. These findings suggest that the active fractions of H. rhamnoides fruit significantly promoted osteoblast differentiation in mesenchymal stem cells and increased osteogenic gene expression, resulting in an improvement in bone mineral density in the osteoporosis mouse model. Taken together, H. rhamnoides fruits are promising candidates for the prevention and treatment of osteoporosis.
