“…In addition, seed priming showed long‐lasting effects by altering plant and fruit physiology in a favourable way, thus increasing the content of biochemical constituents such as total soluble solids, phenol, lycopene and ascorbic acid in the fruits of plants developed from primed seed. Exogenous use of biostimulants through different modes improves the plant growth and yield, as well as the yield nutritional quality under stressful conditions (Ali, Shehzad, et al, 2020). Carillo et al (2019) found an increase in chlorophyll b, anthocyanins, and polyphenols in jute grown in half‐ and quarter‐nutrient solution conditions, because of the application of vegetal‐derived biostimulant from a tropical plant extract (Auxym®).…”

“…As stated by Bulgari, Franzoni, et al (2019), bioactive molecules in biostimulants improve plants' capability to face adverse environmental conditions, acting on the primary or secondary metabolism. It was shown that plant‐based biostimulants improve the target plant growth due to the presence of different phytohormones and other secondary metabolites, vitamins, antioxidants and the inorganic nutrients in the extract, which can affect the plant growth and production directly through improving the plant tolerance against abiotic stresses (Ali et al, 2020). In addition, biostimulants also may suppress dormancy, increase fruit size, enhance root system development, increase the activities of photosynthetic and other vegetative tissues, enhance plant vigour and uniformity, regulate flowering, and stimulate fruit set and ripening (Parađiković, Teklić, Zeljković, Lisjak, & Špoljarević, 2018).…”

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.

Section: Implications Of Biostimulants For Enhancing Crop Physiology Productivity and Qualitymentioning

confidence: 99%

“…Plant growth and yield are influenced by a variety of complex genetic, biochemical, metabolic, and environmental factors that are regulated by internal and external stimulators [ 7 , 9 , 21 , 29 , 74 , 80 , 86 , 129 , 130 , 131 ]. Due to the large diversity of BSs and complexity associated with plant growth and developmental regulation, it is likely that there will be several mechanisms regulating growth, development and responses to various stressors [ 28 , 34 , 42 , 43 , 74 , 80 , 86 , 129 , 131 , 132 ]. For a specific group of BSs such as vermicomposts and their various “teas,” the scientific evidence is indicative that vermi-linked BSs enhanced plant growth and development through bio-stimulatory actions of various phytohormones present in it [ 28 , 70 , 75 , 81 , 130 ].…”

“…In general, BSs promote growth, development, and resilience to abiotic stresses by exerting a bio-stimulatory effect on target plant due to phytohormones, secondary metabolites, and organic and inorganic nutrients [ 28 , 42 , 66 , 94 , 95 , 129 , 131 ]. Furthermore, application of BSs was reported to stimulate seed germination, seedling growth, and crop productivity by promoting primary and secondary metabolisms through the bio-stimulatory actions of signaling bioactive molecules existing in BSs [ 21 , 29 , 34 , 75 ].…”

Demand for organically grown food crops is rising substantially annually owing to their contributions to human health. However, organic farm production is still generally lower compared to conventional farming. Nutrient availability, content consistency, uptake, assimilation, and crop responses to various stresses were reported as critical yield-limiting factors in many organic farming systems. In recent years, plant biostimulants (BSs) have gained much interest from researchers and growers, and with the objective of integrating these products to enhance nutrient use efficiency (NUE), crop performance, and delivering better stress resilience in organic-related farming. This review gave an overview of direct and indirect mechanisms of microbial and non-microbial BSs in enhancing plant nutrient uptake, physiological status, productivity, resilience to various stressors, and soil-microbe-plant interactions. BSs offer a promising, innovative and sustainable strategy to supplement and replace agrochemicals in the near future. With greater mechanistic clarity, designing purposeful combinations of microbial and non-microbial BSs that would interact synergistically and deliver desired outcomes in terms of acceptable yield and high-quality products sustainably will be pivotal. Understanding these mechanisms will improve the next generation of novel and well-characterized BSs, combining microbial and non-microbial BSs strategically with specific desired synergistic bio-stimulatory action, to deliver enhanced plant growth, yield, quality, and resilience consistently in organic-related cultivation.
