“…In 2019 (Figure 1B), only MA reported a significant increase in fruit diameter compared to the control and the other treatments, with an increase of 24.7 mm. Similar results have also been observed by Nagy et al [18] where all algae product treatments significantly affected the apple fruit diameter, where the maximum increment was 30.5% compared to the control. Additionally, Colavita et al [19] showed the effect of seaweed extract on pear fruit, highlighting an average increase of 3% in diameter, 9% in weight, and 26% in the number of cells per area of parenchymatous tissue.…”

The Annurca apple is a typical fruit from Southern Italy that is notable for its high firmness and characteristic flavor, and presents positive effects on human health. The aim of the present study was to improve the agronomic characteristics of Annurca trees and the quality of their fruits by the use of plant biostimulants. We performed the study with three biostimulants (protein hydrolysates, seaweed extracts, and microalgae) to determine their effects on trees and fruits at harvest and during fridge conservation. The measurements in the field concerned the production per plant, the number of fruits, the diameter and fruit weight, the diameter of trunk, the weight of pruning, the first harvest %, and yield efficiency (plant prod./TCSA) for both growing seasons 2018–2019. The analyzed fruit parameters at harvest and during the fridge conservation were: flesh firmness, epicarp color, total soluble solids, pH, and titratable acidity. The results showed positive effects of the biostimulants on the production and the color parameters, especially with microalgae enhancing fruit redness (5-fold) and color index (8.5-fold). In particular, protein hydrolysates and microalgae increased the production (10.4%), diameter of the fruits (7.0%), the first harvest percentage (37.8%), and yield efficiency (6.9%). The tested plant biostimulants showed no significant effect on the measured qualitative parameters. This study represents the first detailed research on the use of different types of biostimulants on Annurca trees and their impact on the quality of its fruits from harvest to storage, and may present a sustainable alternative for the “melaio” processes.

“…The effect of preparations with seaweed extracts was confirmed by higher values in leaf number growth and leaf area, as well as the same treatments showing positively significant values for antioxidant activity and polyphenol content. Similar results for 'Gala Must' apple fruit were obtained by Nagy et al [42] indicating that a biostimulant fertilizer formulation containing seaweed extracts significantly improved antioxidant properties in the studied variety of apples. Ambroszczyk et al [43] proved that tomato fruits treated with biostimulation preparations had significantly higher antioxidant activity compared with fruits not treated with preparations containing marine algae extracts.…”

The purpose of the experiment was to demonstrate a comparison of fertilization with and without biostimulation. A study was carried out in an experimental blueberry field in central Poland (51°55′42.7″ N 20°59′28.7″ E) during the three growing seasons of 2019, 2020 and 2021, on ‘Bluecrop’ shrubs growing at a distance of 1 × 3 m. The plants were re-planted in the spring of each year and irrigated using drip irrigation. The experiment was conducted using a random block design (four fertilizer treatments × five replications × six bushes). The fruits were tested for antioxidant activity and amount of total polyphenols. Additionally, anthocyanin quantitative and qualitative analysis was performed. The results indicated a significant effect of fertilizer combinations on the values of the evaluated parameters. The positive effect of biostimulants on the content of antioxidant compounds in highbush blueberry fruit was significant. In most of the combinations in which additional biostimulants were used, higher values of the analyzed indicators (antioxidant activity and polyphenol content) were observed. The most noteworthy was the T4 fertilization program, where during treatment, soil and foliar fertilization were carried out with preparations that contained biostimulants.

“…An important component of this biostimulant is the seaweed extract, as it was in the research of Frioni et al (2019), who observed similar positive effects of Acadian Marine Plant Extract Powder © on anthocyanin, and phenolic concentration in grapes, which correlated with specific modulation of genes involved in the flavonoid metabolic pathways. Biostimulants based on algae extracts significantly increased Vitamin C content in apples (Nagy, Csihon, & Szabó, 2019), cucumbers (Trejo Valencia et al, 2018) and carrots (Wszelaczyńska, Szczepanek, Pobereżny, & Kazula, 2019). An increased anthocyanin and phenolic content in table grape cv.…”

Plants must cope with different environmental stresses during their whole lifetime. Abiotic stresses like drought, salt, mineral nutrition disturbances and temperature stress are commonly interconnected through some physiological events in stressed plants, such as the synthesis of protective plant compounds as a response to stress. Many of these, produced within plant primary or secondary metabolism, act as functional compounds not exclusively in plants but in other organisms as well. Concurrently, many of the active compounds in biostimulants which can support plant stress tolerance and productivity in adverse growth conditions are the metabolites or intermediates that may influence the plant's edible parts nutritional quality. Such effects of biostimulants application are not elucidated enough, therefore, we aimed to give an overview of recent advances in the research related to the interplay among abiotic stress, plant response, biostimulants effects and plant‐derived functional food, focusing on plant metabolites as the link which connects the environment with the food chain.
