“…As previously described for the seaweed extracts, PH application was often done before and then repeated during and/or after the occurrence of the abiotic stress and this suggests a possible priming action exerted by PHs toward low-temperature thermal stress [77,78] or other abiotic stresses [79]. This hypothesis is also supported by the results of two separate studies [80,81]; one foliar application of PHs applied before or right after (two days) the application of the water stress treatments mitigated the impact of this abiotic stress on the physiology and the vegetative/reproductive growth of grapevines.…”

“…In those studies aiming to test the suitability of PHs in improving the plant tolerance to salinity and cold stress, the biostimulants were applied only as drench, whereas in the trials on drought tolerance, PHs were applied either as drench or as foliar sprays. Most of the PHs adopted were of animal origin (Table 7), whereas in two cases they were either of plant origin [81] or they were described as a mix of amino acids of unknown origin [24]. PHs were applied at concentrations ranging between 0.01 and 0.64%.…”

The application of PHs was often repeated several times during the vegetative season, but in three of the studies they were applied only once [80,81] or twice [24].

Rate and Timing of Application of Biostimulant Substances to Enhance Fruit Tree Tolerance toward Environmental Stresses and Fruit Quality

Biostimulants represent an important category of agricultural inputs characterized by multiple functions. They are used to assist crop growth, yield and to enhance the final quality of produces. Their classification is generally based on claims (i.e., which services they provide to the crop), even though their biological effects are often species-dependent and highly influenced by external factors (i.e., the growing conditions). This review provides a survey of the available scientific literature on the use of biostimulant substances in fruit production, with the specific aim to clarify their predominant mode and time of application. An extremely varied scenario emerged where foliar treatments are common for seaweed extracts, humic and fulvic acids, and where protein hydrolysates and silicon are applied both to the soil (drench) or sprayed to the canopy. Dosages were difficult to compare between the considered studies given the wide range of tested products and the uncertainty in their actual composition. Regarding the number of applications, biostimulants are generally applied following a calendar-approach, covering most of the growing season. When their use is intended to enhance crop tolerance toward environmental stresses, biostimulants are mainly applied before the stressful event to prime plant physiological defenses. Further studies based on multiple-year research projects and standard methodological protocols are urgently needed to verify a clear compliance with biostimulant claims and to evaluate their cost-effectiveness for the fruit production sector.

“…So, the clearest reaction to the application was a drop in the concentrations of compounds related to the flavanols and their precursors or biosynthetic pathways (downregulation of flavonoids and their precursors in PHs). Moreover, the treatment upregulated the concentration of 3-hidroxy-β-ionone, a metabolite involved in lutein and zeaxanthin cleavage, thus dissipating the excess of energy under summer stress [178].…”

Biostimulants in Viticulture: A Sustainable Approach against Biotic and Abiotic Stresses

Climate change and disproportionate anthropogenic interventions, such as the excess of phytopharmaceutical products and continuous soil tillage, are jeopardizing viticulture by subjecting plants to continuous abiotic stress. One of the main physiological repercussions of abiotic stress is represented by the unbalanced redox homeostasis due to the overproduction of reactive oxygen species (ROS), ultimately leading to a state of oxidative stress (detrimental to grape quality). To these are added the direct and indirect damages caused by pathogens (biotic stresses). In light of this scenario, it is inevitable that sustainable techniques and sensitivity approaches for environmental and human health have to be applied in viticulture. Sustainable viticulture can only be made with the aid of sustainable products. Biostimulant (PB) applications (including resistance inducers or elicitors) in the vineyard have become interesting maneuvers for counteracting vine diseases and improving grape quality. These also represent a partial alternative to soil fertilization by improving nutrient absorption and avoiding its leaching into the groundwater. Their role as elicitors has important repercussions in the stimulation of the phenylpropanoid pathway by triggering the activation of several enzymes, such as polyphenol oxidase, lipoxygenase, phenylalanine ammonia-lyase, and peroxidase (with the accumulation of phenolic compounds). The present review paper summarizes the PBs’ implications in viticulture, gathering historical, functional, and applicative information. This work aims to highlight the innumerable beneficial effects on vines brought by these products. It also serves to spur the scientific community to a greater contribution in investigating the response mechanisms of the plant to positive inductions.

“… Li et al (2021) reported the mechanisms at play in the molecular and physiological metabolic response of N. sibirica to salt stress by using comprehensive transcriptome and metabolome profiling. Bavaresco et al (2020) found that protein hydrolysates modulate the leaf proteome and metabolome of grapevines in response to water stress. The mechanism of Se accumulation and tolerance in C. violifolia was also identified using metabolome, transcriptome, and proteome technologies ( Rao et al, 2021 ).…”

The response of okra to drought stress is very complicated, and the molecular mechanisms underlying this process remains ambiguous up to now. In this study, different degrees of water-stress responses of okra leaf were explained by using transcriptomics and metabolomic approaches. The photosynthesis and glycometabolism in okra leaf were both adversely affected by drought stress, leading to inhibition of the carbohydrate metabolic process, and then influencing the secondary plant metabolism. Further, drought stress disturbed amino acid metabolism, especially for the tyrosine-derived pathway as well as arginine and proline metabolism, which have been shown to be significantly enriched under water withholding conditions based on multi-omics conjoint analysis (transcriptome, proteome and metabolome). In-depth analysis of the internal linkages between differentially expressed transcripts, proteins, and metabolites decidedly indicate that tyrosine metabolism could confer tolerance to drought stress by influencing carbon and nitrogen metabolism. These findings provide a whole framework of the regulation and relationships of major transcripts and peptides related to secondary metabolism, particularly, the role of critical proteins and metabolite involved in the change of amino acid metabolism in response to drought stress.
