“…The application of seaweed extracts from Sargassum muticum and Jania rubens significantly alleviated the negative effects of salt through regulation of amino acids metabolism, ionic content balanced and improved antioxidant defence in chickpeas plants. Amino acids such as serine, threonine, proline and aspartic acid were identified in roots as responsible for salt stress amelioration [176].…”

Abiotic stresses strongly affect plant growth, development, and quality of production; final crop yield can be really compromised if stress occurs in plants’ most sensitive phenological phases. Additionally, the increase of crop stress tolerance through genetic improvements requires long breeding programmes and different cultivation environments for crop performance validation. Biostimulants have been proposed as agronomic tools to counteract abiotic stress. Indeed, these products containing bioactive molecules have a beneficial effect on plants and improve their capability to face adverse environmental conditions, acting on primary or secondary metabolism. Many companies are investing in new biostimulant products development and in the identification of the most effective bioactive molecules contained in different kinds of extracts, able to elicit specific plant responses against abiotic stresses. Most of these compounds are unknown and their characterization in term of composition is almost impossible; therefore, they could be classified on the basis of their role in plants. Biostimulants have been generally applied to high-value crops like fruits and vegetables; thus, in this review, we examine and summarise literature on their use on vegetable crops, focusing on their application to counteract the most common environmental stresses.

“…This enhancement was marked by an increase of the branch length and dry weight per plant of 11.55% and 6.45% respectively during the 2016 season. In a study conducted by Abdel Latef et al [36] to assess the potential of two seaweed extracts Sargassum muticum and Jania rubens, a brown and a red macroalgae respectively, in improving growth and mitigating salinity in chickpea plants, the principal component analysis (PCA) showed that growth parameters are closely linked to the photosynthetic pigments. However, Spann and Little [37] demonstrated that the increase in shoot length of sweet orange nursery trees treated by a seaweed extract based on Ascophyllum nodosum during drought conditions could not be linked to photosynthesis.…”

The time when plant biostimulants were considered as “snake oil” is erstwhile and the skepticism regarding their agricultural benefits has significantly faded, as solid scientific evidences of their positive effects are continuously provided. Currently plant biostimulants are considered as a full-fledged class of agri-inputs and highly attractive business opportunity for major actors of the agroindustry. As the dominant category of the biostimulant segment, seaweed extracts were key in this growing renown. They are widely known as substances with the function of mitigating abiotic stress and enhancing plant productivity. Seaweed extracts are derived from the extraction of several macroalgae species, which depending on the extraction methodology lead to the production of complex mixtures of biologically active compounds. Consequently, plant responses are often inconsistent, and precisely deciphering the involved mechanism of action remains highly intricate. Recently, scientists all over the world have been interested to exploring hidden mechanism of action of these resources through the employment of multidisciplinary and high-throughput approaches, combining plant physiology, molecular biology, agronomy, and multi-omics techniques. The aim of this review is to provide fresh insights into the concept of seaweed extract (SE), through addressing the subject in newfangled standpoints based on current scientific knowledge, and taking into consideration both academic and industrial claims in concomitance with market’s requirements. The crucial extraction process as well as the effect of such products on nutrient uptake and their role in abiotic and biotic stress tolerance are scrutinized with emphasizing the involved mechanisms at the metabolic and genetic level. Additionally, some often overlooked and indirect effects of seaweed extracts, such as their influence on plant microbiome are discussed. Finally, the plausible impact of the recently approved plant biostimulant regulation on seaweed extract industry is addressed.

“…The variable effect observed might be related to the complex composition of bark extract. Unlike other plant-derived products rich in nutrients, mainly from seaweed, 46 the bark of A. dealbata contains abundant and complex secondary compounds such as gums, 33 sterols, 34,35 phenols, flavonoids, and tannins, 36,37 the function of which is not primarily related to plant nutrition.…”

“…38,42,43 Biostimulants have been proven to promote plant growth, 42,41,44 and they were particularly relevant to the development of the stress tolerance of crops under unfavorable conditions. 43 Under different environmental stresses, plant biostimulants were especially effective in overcoming the negative effect of salt stress on different crops such as Zea mays L., Cicer arietinum L., Lactuca sativa L., or Cucurbita pepo L., [45][46][47][48] respectively. Plant biostimulants also showed the potential to improve tolerance to drought stress in agricultural species such as Citrus sinensis L. Osbeck, 49 Glycine max L. Merr.…”

“…53,[56][57][58][59][60] Within this uncertain scenario, the use of plant biostimulants has been proposed as an innovative, sustainable and eco-friendly strategy, contributing to addressing the challenge of satisfying the food demand of a growing world population. 41 Currently, the most common biostimulant formulations in use are extracts based on studies of seaweed preparations 46,61,48 while studies that evaluate the biostimulant activity of extracts from trees releasing bioactive compounds are limited. 62,63 Bearing in mind the interest in obtaining potential uses for the A. dealbata waste and, considering the positive bioactivity of its bark extracts that was found previously, it was hypothesized that natural compounds extracted from the bark of A. dealbata will show a biostimulant effect under stress conditions.…”

BACKGROUND Acacia dealbata Link is an invasive plant worldwide. Finding potential uses for its waste that contribute to controling its spread and result in benefits for agriculture has recently become a new topic of research. This study aimed to evaluate the potential biostimulant effect of bark extract derived from the management of A. dealbata (0, 450 or 900 ppm) on onion plants growing under stressful conditions, such as in soils treated with saline solutions (0, 60 or 120 mmol L−1 NaCl) and with reduced irrigation (100%, 50% or 25%). RESULTS A. dealbata Link bark extract significantly increased height as well as leaf, root and total biomass of plants in soils irrigated with NaCl solution (120 mmol L−1). These plants also had a higher content of Cl in roots, but a lower content of P in leaves and of K in bulbs. The 450 ppm bark treatment additionally increased the protein content in leaves and decreased the Na and Mg content in bulbs and bulbs and roots, respectively. The bark extract also increased the sugar content in plants under saline conditions. However, the effect of bark extract was negligible on plants that grew under drought stress. CONCLUSION Results revealed that the bark extract might attenuate stress effects in plants growing at high salinity levels, probably by increasing their sugar and protein content and via the accumulation of ions in the roots. Although additional experiments are required, we suggest that the bark extract of A. dealbata has potential applications in agriculture concerned with biostimulant formulations. © 2019 Society of Chemical Industry
