“…20 Plants of the Reynoutria genus contain a big complex of biologically active substances, including phenolic compounds, such as, resveratrol, piceid, furans, phenol carboxylic acids and their derivatives lignans, coumarins, catechins, naphthoquinones, and anthraquinones. [21][22][23] In this context, the main objective of this work was to evaluate the effect of foliar applications of plant extracts (nettle and Japanese knotweed), as potential compounds in crop protection strategies, on grapevine bioactive compounds and antioxidant capacity, aiming to contribute to the increase of the profitability and sustainability of vines production.…”

BACKGROUNDPlant‐based extracts have been recently used as sustainable tools to improve biotic and abiotic stress tolerance and increase grape (Vitis vinifera L.) quality. However, knowledge about the effect of these extracts on secondary metabolism compounds, that are fundamental for grape and wine quality, is still scarce. In this study, a trial was installed in an experimental vineyard with the variety Touriga Franca located at University of Trás‐os‐Montes e Alto Douro, Baixo Corgo sub‐region of the Douro Demarcated Region, Portugal in two growing seasons: 2019 and 2020. The aim was to evaluate the effect of foliar application of nettle (Urtica spp.) extract (NE) and Japanese knotweed (Reynoutria japonica) extract (JKE) on grapevines leaves and berries bioactive compounds contents and antioxidant activity, at veraison and harvest.RESULTSThe application of NE increased the total carotenoids in leaves and the total phenolics content and the antioxidant activity (ferric reducing antioxidant power, FRAP) in berries while JKE increased flavonoids content in leaves and the antioxidant activity (2,2‐diphenyl‐1‐picrylhydrazyl, DPPH) in berries.CONCLUSIONThese extracts seem to have a stimulatory effect on grapevine, enhancing bioactive compounds contents and antioxidant capacity and, consequently, the physiological performance of the plant and the quality of the berries. © 2024 The Authors.

Currently, a promising direction for the development of organic agriculture is research on the potential and action spectrum of biologically active compounds produced by vascular plants and the improvement of technologies for their application in production. Buckwheat (Fagopyrum esculentum Moench) is a plant species with an exceptional ability to produce secondary metabolites, including flavonoids. It was discovered that F. esculentum plants, especially those with red and red-green stems, were a promising source of flavonoid compounds (up to 3%). Buckwheat extracts had high antioxidant activity, which varied from 19.8–99.4% depending on their concentration, and positively influenced root formation in F. esculentum plants. The strongest growth-promoting effect on plant roots was produced by 0.1-1.0% extracts from buckwheat variety Bashkirskaya krasnostebel’naya and local varieties Izumrud and Pri 7 with red and red-green stems. Treating buckwheat plants with the extracts from F. esculentum under the conditions of Primorsky kray (Russia) at the stages of bud formation increased the accumulation rate of flavonoids in their fruits up to 0.22%. The extracts from F. esculentum might be used in organic agriculture as the natural sources of biologically active compounds for promoting the growth of cultivated plants.

Knotweed (Reynoutria sp.) plants are known in the world mainly as invasive plants. However, it is known that their rhizomes or leaves contain secondary metabolites with biological activity. Our goal was to determine which of the three knotweed plants (Reynoutria japonica, Reynoutria × bohemica, and Reynoutria sachalinensis) is most suitable for seed growth stimulation. We tested alcoholic extracts of all three knotweed species by seed priming method on wheat germination and seedling characteristics, when 12 measured characteristics were monitored. Extracts from all three species of Reynoutria sp. generally showed an improvement in wheat germination and growth compared to the control. R. × bohemica appears to be the best source for stimulating wheat growth, as seedling vigor indexes I and II, R/S dry weight, shoot and seedling lengths, root, shoot, and seedling dry weights were significantly different (ANOVA, Duncan’s test, α < 0.05). The plants Reynoutria spp. seem to be possible sources for the protection and stimulation of agriculture crops.
