“…These authors point out that the application at the beginning of maturation (veraison stage), which promoted the increase of anthocyanins, may be related to the phenylpropanoid route induced by higher sugar content, generating an increase in secondary metabolism, including anthocyanins and other flavonoids. Viencz et al (2020) observed an increase of phenolic compounds of 'Irati' plums, with positive linear effect according to the doses of the product containing the seaweed extract A. nodosum.…”

In viticulture, various techniques can be used to improve productivity, tolerance to biotic or abiotic stress, the quality of grapes and wines such as the use of plant regulators and biostimulants. Thus, the objective of this work was to evaluate the effect of application of abscisic acid (S-ABA), Ascophyllum nodosum (A. nodosum) seaweed extract and Aloe vera (A. vera) gel on phenolic composition and chromatic characteristics of grapes from the 'Cabernet Sauvignon' variety. The experiment was conducted in a commercial vineyard in Campo Largo - Paraná, in two consecutive seasons, 2017/18 and 2018/19, involving the following treatments: 1) control; 2) (S-ABA) 400 mg/L; 3) S- ABA 600 mg/L; 4) A. vera gel 200 mL/L; 5) A. vera gel 400 mL/L; 6) seaweed extract 0.2 mL/L; 7) seaweed extract 0.4 mL/L. Two applications were performed with the seaweed extract and A. gel when the bunches were at veraison stage (50 and 75% of grape berries with coloration). Total anthocyanins content, total polyphenols content and activity of phenylalanine ammonia-lyase (PAL), polyphenoloxidase and peroxidase enzymes were assessed in the berries skin. Total anthocyanins, individual anthocyanins and total polyphenol contents as well as lightness, chroma and hue angle were analyzed in the corresponding wines. S-ABA increased the content of anthocyanins and total polyphenols, as well as the activity of PAL in the first season. A. nodosum (AN) seaweed extract increased the total polyphenol content, total anthocyanins content and PAL in the berry skin of 'Cabernet Sauvignon' variety. S-ABA increased the total polyphenol content and anthocyanins in wine, as well as the A. nodosum, in at least one of the evaluated seasons.

“…Seaweed extract significantly increased chitinase, glucanase, peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia-lyase (PAL), and lipoxygenase enzyme activities [16][17][18]. The AnE treatment of postharvest plums increased polygalacturonase (PG) activity [180].…”

“…The rigorousness of Fusarium head blight, which is caused by Fusarium graminearum (Gibberella zeae), was decreased by the application of AnE to Triticum aestivum (wheat) [89]. Similarly, at a concentration of 0.4 mL/L, AnE reduced brown rot disease in the plum fruits by 50%, a disease which is caused by members of the Monilinia genus: M. fructicola, M. laxa, and M. frutigena [180]. Paiva et al [192] reported that at a concentration of 40 mL/L of AnE, the mycelia growth of the fungus Rhizopus stolonifer was significantly reduced, ultimately decreasing the incidence of soft rot by up to 22.3% in postharvest Fragaria ananassa (strawberry).…”

“…Chrysargyris et al [159] observed that the foliar application of 1% biopost-AG200 biweekly for up to five weeks increased the comparative growth and postharvest quality of lettuce in a potassiumdeficient condition by enhancing antioxidant activity. Applying Ascophyllum nodosum to postharvest plums increased the total phenolic content (TPC) in "Irati" plums [180]. The treatment of broccoli florets with A. nodosum and amino acid-based filtrate increased the TPC, sinapic acid, and quercetin levels [208].…”

Algae are existing macroscopic materials with substantial benefits, including as important growth regulators and macronutrients and micronutrients for the growth of healthy crop plants. Biofertilizers obtained from algae are identified as novel production fertilizers or innovative biofertilizers without the detrimental impacts of chemicals. Seaweeds contain many water-soluble minerals and nutrients that plants can easily absorb and that are valuable for crop plants’ growth. At present, Ascophyllum nodosum (L.) Le Jolis extract outperforms chemical fertilizers in terms of increasing seed germination, plant development, and yield, as well as protecting plants from severe biotic and abiotic stresses. A. nodosum contains bioactive compounds that exhibit an array of biological activities such as antibiotic, anti-microbial, antioxidant, anti-cancer, anti-obesity, and anti-diabetic activities. A. nodosum extract (AnE) contains alginic acid and poly-uronides that improve soil’s water-carrying ability, morsel structure, aeration, and capillary action, stimulating root systems in plants, increasing microbial activity in soil, and improving mineral absorption and availability. The scientific literature has comprehensively reviewed these factors, providing information about the different functions of A. nodosum in plant growth, yield, and quality, the alleviation of biotic and abiotic stresses in plants, and their effects on the interactions of plant root systems and microbes. The application of AnE significantly improved the germination rate, increased the growth of lateral roots, enhanced water and nutrient use efficiencies, increased antioxidant activity, increased phenolic and flavonoid contents, increased chlorophyll and nutrient contents, alleviated the effects of abiotic and biotic stresses in different crop plants, and even improved the postharvest quality of different fruits.

“…Seaweed algae extracts are complex products, containing plant hormones, brassinosteroids, betaines, polyamines, polymers and also macro and micronutrients [11]. Although the complexity of their composition tends to make it difficult to clarify their mode of action [6,9,12], several studies have shown beneficial effects from the use of seaweed extracts for the alleviation of abiotic [13][14][15] and biotic [16,17] stresses, and in increasing crop productivity and/or product quality [18][19][20], even if they provide minute quantities of nutrients [5].…”

Response of Hops to Algae-Based and Nutrient-Rich Foliar Sprays

Over recent years, some hopyards of northeast Portugal have presented poorly developed plants and reduced productivity. In this study, an attempt was made to improve the homogeneity of hop fields and restore their productivity by using plant biostimulants as foliar sprays. The experimental apparatus included four field trials carried out in four plots of different plant vigour, as evaluated by farmers over previous years (weak, fair, good and very good). The experiments were arranged as a factorial of foliar treatment (two plant biostimulants containing extracts of seaweed algae and an untreated control) and year (2017 and 2018). The plot and the year influenced greatly almost all the measured variables related to tissue nutrient concentration and crop performance. In the control plots, cone dry matter (DM) yield varied from 83.3 to 394.4 g plant−1 from the weak to the very good plots. In 2018, cone DM yield was significantly higher than in 2017. The use of foliar sprays influenced less the elemental composition of plant tissue than the plot or the year. The use of foliar sprays only increased significantly crop yield in the plot of weak plant vigour. The foliar treatments did not increase α- and β-acid concentration in the cones; in the control treatment of the most productive plot, the values were, respectively, 11.2 and 3.9%. Although seaweed extracts tend to help plants cope with several abiotic and biotic stresses, they showed to be effective in mitigating the stress that is affecting these plants, which probably is poor soil drainage caused by the flooding irrigation system, only under conditions of severe stress.
