Endosperm, an ephemeral and storage tissue, serves as a source of nutrition and protection during embryo development and germination. It can be used for the cultivation of polyploid plants in vitro. Here, results of plant regeneration and acclimatization from the endosperm-derived calli of four cultivars of Actinidia arguta has been presented. Seeds excised from fresh fruit and dry seeds stored for one year served as the sources of endosperm explants of selected tetraploid cultivars of A. arguta. Callus Induction Medium (CIM; containing 0.25, 0.5, or 1 mg/l of TDZ) and Actinidia Endosperm Medium (AEM; containing 2 mg/l of 2,4-D and 5 mg/l of kinetin) were used to study the organogenic responses of the calli. On AEM, the source of explant did not significantly affect the rate of callus induction for any of the tested cultivars; no organogenic events were observed. In contrast, on CIM both the source of explants and the cultivar origin caused significant differences in callus formation and subsequent organogenic events. Histological and ultrastructural analyses revealed the adventitious nature of shoot bud formation on these media. The most efficient elongation of shoot buds was achieved after transferring organogenic calli with adventitious shoot buds to a medium supplemented with zeatin or meta-topolin. Robust root induction with minimal basal callus formation occurred on the medium with indole-3-acetic acid. Flow cytometric analysis revealed that the nuclear DNA content in the leaves of some regenerants was approximately 50 % higher (4.5 pg/2C) than that in leaves from the tetraploid seedlings (3.1 pg/2C),which confirmed that those regenerants originated from the endosperm. The regeneration of such hexaploid plants was more efficient when endosperm from fresh seeds served as an explant; therefore, fresh rather than dry seeds are recommended for endosperm-derived plant production. The hexaploid plants of A. arguta can serve as an important source of breeding material.

Nowadays, the trend related to healthy eating is constantly growing among consumers. The juices based on kiwiberry containing over 20 vital nutrients may have a potential for usage in developing innovative products targeting health-concerned consumers. The aims of the study were: (1) to identify the volatile compounds of kiwiberry juice and its mixes with basic organic juices; (2) to determine the sensory characteristics and level of liking with regard to the tested samples and (3) to select the juice-mix with the highest sensory quality properties and liking. The measurements of volatile compounds in juices were made using a Heracles Neo ultrafast gas chromatograph (HS-GC). The sensory characteristics of the juices were assessed by Descriptive Quantitative Analysis, whereas the consumers’ overall liking was assessed on a 9-point hedonic scale. It was stated that the examined juices differed in the pattern of volatile compounds as well as in the sensory properties and the level of liking. The increasing addition of apple and pear juice to kiwiberry based juices in different ratios contributed to the exposed volatile compounds responsible for floral, sweet and fruity odours. The juice mixes with higher addition of apple or pear juices were more harmonized in terms of sensory image and represented higher levels of overall liking among consumers.

Among the actinidia genus (Actinidia spp.) native to China, few species are grown commercially for their edible and healthy fruits. As they are dioecious plants, a lot of interest is paid to effective pollination and to insects as the most efficient pollinators. In this study we have concentrated on the composition of volatile compounds in male flowers of four different actinidia species (A. chinensis var. deliciosa, A. arguta, A. kolomikta and A. polygama) and on the diversity between male and female flower volatiles for the two most winter-hardy species (A. arguta and A. kolomikta) with growing commercial value. Analyses were provided using gas chromatography with mass spectrometry (GC-MS). In total, 120 compounds were found in 15 actinidia genotypes. However, the number of identified compounds varied between species. Different main compounds or groups of volatile compounds characterised flowers of every species. Smaller differences were observed between male and female flowers of the same species. Our results suggest that actinidia flowers could be attractive to pollinating insects.

This study analysed the impact of high pressure processing (HHP) on the inhibitory effects (IC50) of kiwiberries (cv. 'Weiki'), on the formation of advanced glycation end-products (AGEs) and the activity of angiotenisn-converting enzyme (ACE) and the enzyme acetylcholinesterase (AChE). The polyphenol profile (HPLC-MS/MS) and antioxidant capacity (PCLACW, ABTS, FRAP) were also studied. HHP-treated 'Weiki' (450 MPa/5 min and 650 MPa/5 min) was the most potent inhibitor of AGEs in the BSA-GLU model (6.52 mg/mL on average) relative to other materials (12.09–7.21 mg/mL). Among all samples assayed in the BSA-MGO model (61.97–14.48 mg/mL), HHP-treated 'Weiki' (450 MPa/5 min) showed the highest anti-AGE activity (12.37 mg/mL). Pressurization (450 MPa/5 min) significantly enhanced the anti-ACE (14.09 mg/mL) and anti-AChE (16.95 mg/mL) potentials of the tested extract relative to the other materials (23.75–14.50 mg/mL and 37.88-19.69 mg/mL, respectively). Pressurization increased polyphenol content and antioxidant capacity of the samples analysed.

This study aimed to investigate the impact of convective and vacuum drying performed at different temperatures on the content of bioactive components of kiwiberry. Dried fruits obtained from Geneva and Weiki cultivars were analyzed for total carotenoid content, total phenolic content (TPC), and antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. The secondary goal was to establish drying kinetics and to find the best-fitting model for the drying process. The results showed that the highest total carotenoid content was found in Geneva fruits dried by vacuum method and was equal to 39.55–90.27 µg/g dry matter (d.m.). Considering free radical scavenging activity, the best results were also achieved for vacuum dried Geneva cultivar. These samples exhibited EC50 equal to 0.16–0.51 mg d.m./mL and 0.05–0.24 mg d.m./mL as evaluated using DPPH and ABTS assays, respectively. Vacuum drying method usually better preserved the phenolic content of kiwiberry—samples dried at 50 °C did not differ significantly from fresh material. Generally, the shortest drying time was observed for the samples dried at 70 °C regardless of the drying method. Changing the temperature during drying from 80 to 50 and 60 °C did not cause expected benefits regarding chemical property preservation. In most cases, the Midilli et al. model represented the best fit to describe obtained drying kinetics.

Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. is functionally a cryptic dioecious plant and successful pollination is crucial for achieving high quality fruit. The extent and bases of morphological variability in female genotypes have been well studied, but here we focus on the males. Mature plants of seven male A. arguta genotypes were studied in 2016 and 2017 during which a suite of phenological and morphological features was measured on ten randomly chosen one-year-old canes on each plant. This analysis was complemented by two other, specialized measures potentially related to pollination efficiency, namely pollen quality, and quantity. The time of bud break was similar each year across all genotypes and the pollen quality was uniformly very high (viability – 95.0–99.9% and germination – 89.0–97.3%). However, the ten genotypes exhibited high variability in both the number of flowers per inflorescence and pollen quantity, indicating marked differences in their flowering potential and efficiency as pollinizers. The male kiwiberry indicators developed in this study – flowering potential and pollen efficiency, appear to be effective tools for the comparative evaluation of male A. arguta genotypes.

Actinidia arguta known as the 'kiwiberry' or 'mini kiwi' is relatively new among the cultivated berry species. Recent studies indicate the kiwiberry fruit could be an important source of many health-promoting compounds. A knowledge-based fertilisation concept was evolved to define optimal strategies for feeding Actinidia with nitrogen (N) because a deficit and excess of N both have a negative impact on plants and the surrounding environment. Kiwiberry yield and fruit internal quality significantly depended on soil N level, cultivar and growing season. A higher soil N led to an increase in carotenoid content and a decrease in phenolic content, whereas ascorbic acid and glutathione contents were not affected by soil N fertility. Under the highest N dose, enzymatic antioxidants were activated. Trolox equivalent antioxidant capacity clearly decreased with an increasing N level. Competent and skilful fertilisation management should focus on balancing a high fruit yield and maintaining their high quality. Based on yield level and fruit antioxidant potential, the N guide values for A. arguta vary between 30 and 50 mg N per kg-1 of soil. The recommended N dose may depend on overall soil quality traits and cultivar N demand, as well as on weather conditions. © 2020 Society of Chemical Industry.

Nutrient use efficiency and overall plant fertilization strategies are key issues in food production in increasingly adverse environmental conditions. The plant Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. is a species that has increased cultivation in recent years. The aim of this study was to assess seasonal leaf macronutrient changes and the relationship between soil nitrogen (N) fertility and N, as well as the concentration of other leaf essential macronutrients. The experiment was conducted during the growing seasons of 2015–2016 and tested two cultivars: “Weiki” and “Geneva”. Soil N level had a significant impact on the concentration of all leaf macronutrients, except sulfur, in both cultivars. Leaf macronutrient concentration was significantly lower in 2015, which was characterized by a higher average temperature and lower precipitation than the long term averages. A clear downward trend for leaf N and potassium concentrations was observed during the vegetation period. In contrast, leaf calcium and magnesium concentrations increased gradually throughout the season, while phosphorus and sulfur concentration changes were more cultivar dependent. In the soil and climatic conditions in which study was conducted (Central Europe), a time from mid-July to mid-August seems to be the suitable for leaf sampling for diagnostic purposes. Fruit macronutrient composition was predominantly cultivar and year dependent.

Kiwiberry (Actinidia arguta) is dioecious species which is now commercially grown in several countries worldwide. A study was conducted to determine the influence of five pollen sources derived from A. arguta (three cultivars), A. arguta var. purpurea ‘Rot’ and A. chinensis var. deliciosa ‘Tomuri’ on fruit and seed characteristics for three female A. arguta cultivars. Average fruit weight and biochemical features—fruit total phenolic concentration (TPC), ascorbate (ASC), pigments, total antioxidant activity and seed proteins profile were evaluated. TPC was determined using the Folin–Ciocalteu reagent assay. ASC, individual phenolic compounds and pigments composition were analysed using HPLC technique. Seed protein composition was analysed based on SDS-PAGE. Fruit phenolic and dry matter contents were influenced to a large degree by pollen sources while ASC content did not. The type of male and female parents used in the study were found to have a considerable effect on these parameters. The biggest differences in fruit phytocompound contents were found between female parents. The ‘Geneva’ cultivar showed the highest concentration of the most bioactive compounds tested. Four phenolic acids and five flavonoids were present in the highest concentrations in tested kiwiberry fruit. Actinidia chinensis var. deliciosa ‘Tomuri’ pollen clearly modified the seed protein spectrum with a 17 and 23 kDa protein. The obtained results indicate that to achieve desired fruit biochemical characteristics, the pollen source (male vines) should be selected individually for particular female cultivars, especially in the case of polyphenol content. Our findings suggest that not only A. arguta but also A. arguta var. purpurea and A. chinensis var. deliciosa ‘Tomuri’ males may be suitable as pollinizers for kiwiberry fruit production.

The aim of this study was to analyze the impact of osmotic solutions and temperature on the osmotic dehydration (OD) of two cultivars of kiwiberry. OD was carried out in sucrose, xylitol and maltitol solutions at 30 °C and 50 °C, respectively. The process of osmotic dehydration was described by the means of water loss (WL), solid gain (SG), weight reduction (WR), and water content changes. Moreover, dehydration was described by mathematical models often used in the literature. The highest WL, WR and SG values were observed for samples treated by xylitol and maltitol at 50 °C. The statistical analysis of the mathematical modelling of the process showed that in most cases, the Peleg’s equation exhibits better fitting for the experimental data.

Consumers and scientists exhibit a growing interest in bioactive ingredients of natural origin with strong pro-health effects. Such properties have been found in fruits of of Actinidia argute, commonly known as kiwiberry (mini kiwi or hardy kiwi). Appropriate methods and parameters of the drying process enable obtaining a product with preserved high pro-health properties. The obejctive of this paper was to study the influence of the selected drying methods on the drying kinetics of actinidia. Commonly known mathematical models were used to describe the process. The kinetics of convective, microwave-convective, infrared and vacuum drying was investigated. The process was performed until samples reached dimensionless moisture ratio (MR) of 0.02. The quickest method was vacuum drying reaching moisture ratio target after 286 min, and the slowest was convective drying characterized by 1352 min of drying. In general, Midilli et al.’s model was evaluated as the most adequate for description of the moisture transfer in the fruit samples.

The kiwiberry (Actinidia arguta) is a new product on the market that is enjoying growing consumer acceptance around the world. This widespread interest has created increased demand for identification of the kiwiberry’s nutritional health benefits. Containing over 20 essential nutrients and a range of vitamins, the kiwiberry comes near the top of fruits classed as superfoods. It is one of the richest sources of vitamin C with up to 430 mg/100 g fresh weight (FW) and is considered the richest dietary source of myo-inositol (up to 982 mg/100 g FW). The kiwiberry is also one of the richest sources of lutein (up to 0.93 mg/100 g FW) in commonly consumed fruit. Furthermore, containing up to 1301.1 mg/100 g FW phenolics and significant amounts of the essential minerals of potassium, calcium and zinc, the kiwiberry rates very highly as a ‘healthy food’. The type and number of this fruit’s medicinally promising nutrients have motivated ongoing investigations into its antioxidant, anti-tumour and anti-inflammatory properties. Early research has pointed to the kiwiberry being a very promising treatment for some cancers and health issues involving the gastrointestinal system, hypercholesterolemia and certain cancers. A pharmaceutical composition of A. arguta, A. kolomikta, and A. polygama extracts has already been registered for the prevention and treatment of some immune (inflammatory) mediated diseases, as well as the treatment of some non-allergic inflammatory diseases. This paper reviews and highlights the limited nutritional and therapeutic information currently available on the kiwiberry, a minor fruit possessing such major properties.

Shrub species selection for road-side planting should consider their ability to cope with stress factors imposed by road trafic. In our examination we evaluated durability of 28 ground-covering woody species and cultivars in road-side environment in Warsaw. A dendrological inventory of planting beds located along Niepodległości Avenue was carried out 11 years after planting. The survival rate of each planted group of shrubs (a patch) was determined. Electrical conductivity of soil in planting beds was measured in order to determine soil salinity. Planting beds were divided into 3 groups: (1) wide beds at street corners, (2) narrow beds between pavements and interior roads, (3) road-side beds between interior roads and main roads. The results showed that the greatest number of shrubs was lost in the road-side planting beds, but in the wide beds and the narrow beds there were also some plant losses. The most resistant species to road-side environment were Spiraea × cinerea ‘Grefsheim’, certain cultivars of Spiraea japonica, Rosa rugosa and Ribes alpinum ‘Schmidt’.

There are no published results focusing on the study of hardy kiwifruit as a supplementation to the atherogenic diet. We hypothesized that hardy kiwifruit (Actinidia arguta (A. arguta)) from Poland possess better pro-healthy action than two Asian varieties (Hayward and Bidan). We tested this hypothesis by measuring the metabolic reactions of rats loaded with 1% cholesterol and supplemented with 5% of hardy kiwifruit (A. arguta), Hayward, or Bidan in their diets. The experiment was performed on 71 male Wistar rats. Cholesterol showed a significant impact on the rise of liver somatic index, while lipid profile improved by decreasing the levels of TC, LDL-C, TC/HDL-C, AI, TG, and increasing HDL-C in the serum of rats (P < .05). Total plasma antioxidant capacity determined by ABTS, FRAP, and DPPH assays was increased. ALP in rat serum was higher in groups receiving cholesterol diets and kiwifruit. A decrease in fibrinogen as well as prolonged prothrombin time and a reduction of the MPO in serum were estimated. The smallest percentage of lesions in the aortic arch was in the ChGeneva, ChWeiki, and ChAnna. Similarly, the smallest fatty liver disease was recorded in the ChGeneva and ChAnna groups. The distribution of lipids in the liver from these groups had a character of “mosaic,” in hardy/mini kiwifruit (Jumbo), Hayward, and Bidan was distributed uniformly. The longest villi were in ChWeiki, and significantly lower in ChHayward and ChBidan. The present results support our hypothesis that A. arguta showed better pro-health impacts in rats loaded with cholesterol than Hayward and Bidan kiwifruit, and, for the first time, the positive nutritional effects of supplemented A. arguta for hypercholesterolemia are noted.

The aim of this research is to identify and compare the bioactive compounds, antioxidant capacities and binding potentials to human protein in different varieties of hardy kiwi (Actinidia (A.) arguta), 'Hayward' (Actinidia deliciosa) and less - known 'Bidan' (Actinidia eriantha). Polyphenols, flavonoids, flavanols, tannins, vitamin C, lutein, zeaxanthin and dietary fibers were significantly higher in cultivar 'M1' among the A. arguta than in 'Hayward'. The binding properties of studied kiwi fruits were determined by interaction of polyphenols with human serum albumin (HSA). An internal standard FTIR technique allowed the quantitative comparison of specific IR absorption bands (Amides I, II, III) of different kiwi fruit samples after interaction with HSA. It was shown that the antioxidant and binding capacities and FTIR quantitative estimations of A. arguta fruits were significantly higher than in 'Hayward', but lower than the 'Bidan'. In MS spectra were found some slight differences in A. arguta kiwis in comparison with 'Hayward' and 'Bidan'. Two A. arguta cultivars were similar to 'Bidan'. The interaction of polyphenols with HSA, evaluated by fluorometry/FTIR, made it possible to compare the bioactivity of different cultivars and families. In conclusion, for the first time fruits A. arguta, cultivated in Poland, were compared with widely consumed kiwi fruits, using advanced analytical methods. The high bioactivity and nutritional value of A. arguta fruits from Polish ecological plantation enables us to recommend them for marketing and consumption.
