“…In the presented research, the inoculum used slightly influenced the content of phenolic compounds, which was in line with the variability in the antioxidant capacity of the examined apple tissue. Phenolic compounds showed high antioxidant activity and a high positive correlation with total antioxidant activity, which has been revealed in many studies [7,60]. In the leaves of inoculated Lactuca sativa var.…”

“…Health-promoting and protecting attributes of phytochemicals in edible horticultural crops have also led to an intensive search for different ways of increasing their contents. One promising approach in sustainable intensification seems to be the use of microorganism-based products called biofertilizers/biostimulants [7,10,13,28].…”

“…In light of these threats, more environmentally friendly methods of soil enrichment and crop protection are being sought compared with those commonly used in agricultural practices today [1][2][3][4]. The inclusion of microorganism-based products in crop management systems due to the specific role of these rhizosphere organisms in plant performance (plant health and vigor) appears to be one option for reducing the amount of agrochemicals used [1,[5][6][7][8][9][10][11]. Soil biota, such as plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF), individually and/or in co-inoculation (as a bacterial-fungal inoculum to combine the benefits of each) have been tested as a means of increasing the plant nutritional status [8,[12][13][14][15], water status [16][17][18] or the host's resistance to biotic stress factors [8,11,19], including soil replant disease [20].…”

“…A plant antioxidant defense network influenced by PGPR and/or fungal inoculum can be both enzymatic and/or non-enzymatic in nature, with a direct effect on the plant chemical composition [12,[25][26][27]. Furthermore, activation of the secondary metabolism by microorganisms may have an additional effect on the internal quality of the final products, including a greater quantity of healthpromoting phytochemicals such as flavonoids, anthocyanins, vitamins, phytoestrogens, and carotenoids [2,7,13,28]. The potential role of AMF in maintaining fruit quality in future climate change scenarios has also been discussed [29].…”

“…Only a small number of cultivars have been analysed in these studies, despite cultivated species being characterized by a great number of cultivars with a high variation in internal quality traits that, in turn, are subject to the influence of several external factors [31,32]. Very little data in the literature can be found on fruit nutraceuticals due to the biofertilizer used [28] including apple [7,14], whereas the diversity and content of phytochemicals in plant products are affected by different variables [32], such as plant genotype, weather, and agronomic factors (management, soil mineral nutrients, drought, salinity, harvest season, and agrochemicals). Hence, research on microorganisms' mechanism of action and their impact on the quality of horticultural products is still deficient and at times contradictory.…”

This study investigated the antioxidant status of roots, leaves, and fruit upon microbial inoculation (AMF+PGPR, arbuscular mycorrhizal fungi, and plant growth-promoting rhizobacteria, respectively) of young organically farmed apple trees over two growing seasons. Three cultivars—‘Topaz’, ‘Chopin’, and ‘Odra’—were selected to test the relationship between inoculation and enzymatic and non-enzymatic antioxidant components. The antioxidant metabolism was highly dependent on tissue type and growing season. The greatest effect on antioxidant status following application of the inoculum was found in roots, then leaves, but it was almost negligible in fruit. Roots were influenced most by application of the inoculum in the first growing season, while leaves were influenced most in the second season. Considerable differences between the inoculated and control plants were found for root glutathione reductase (GR) and catalase (CAT) activity, as well as glutathione and ascorbate contents; root phenolics were not influenced by inoculation. In the case of leaves, effect of microbial inoculation on GR activity was revealed in the first growing season, while for global phenolics in the second season, and only the concentration of glutathione was significantly higher in the leaves of inoculated trees in both growing seasons. Leaf ascorbate content and CAT activity were not influenced by the microbial inoculation. The control and inoculated trees expressed a similar total antioxidant capacity, irrespective of the tissue type tested. Furthermore, the response of the cultivars to inoculation varied and also changed in consecutive growing seasons. Based on this study, it is likely that the effect of microbial inoculum as a tool for enhancing health-promoting properties in the fruit of perennial plants is weaker than that described for vegetables where different plant organs are edible.

Summary The nutritional properties and health potential of oils from 15 various cultivated and wild plants were investigated on the basis of the fatty acids profiles, total carotenoids and tocopherols content, antioxidant properties and health potential indexes such as atherogenicity index (AI). The oil contents of the plants varied between 0.9 g/100 g for lychee seeds and 29.7 g/100 g for borage seeds. The tocopherol content in oils ranged from 0.31 (lingonberry fruits) to 226.23 mg/100 g (hawthorn pulp), carotenoids ranged from 0.36 (borage seeds) to 14.22 mg/100 g (blackcurrant seeds). In four oils (raspberry seed, strawberry seed, lingonberry fruits, blackcurrant seeds) the PUFA contents contributed over 70% of the total fatty acids (FA), which was associated with the best values health potential indexes. It was found that TAC (Total Antioxidant Capacity) can be an indirect measure of the levels of carotenoids and tocopherols in oils. Additionally, a positive correlation between the level of carotenoids and the FA n‐3 was demonstrated. Determining such relationships may facilitate research into new sources of valuable edible oils useful for the production of functional foods, dietary supplements and cosmetics.

The use of ecofriendly strategies, such as the use of Plant Growth Promoting Bacteria, to improve the yield and quality of crops has become necessary to satisfy the growing demand of food and to avoid the use of chemical fertilizers and pesticides. In this study, we report the effects of an innovative microbial inoculation technique, namely Effective Microorganisms (EM), compared with traditional approaches, on productivity and nutritional aspect of four tomato varieties: Brandywine, Corbarino Giallo, S. Marzano Cirio 3, S. Marzano Antico. Results showed an increase of plant productivity as well as an enhanced antioxidant activity mainly in San Marzano Antico and Brandywine varieties treated with EM technology. Moreover, the polyphenol and carotenoid contents also changed, in response to the plant treatments. In conclusion, the application of EM® technology in agriculture could represent a very promising strategy in agricultural sustainability.
