Seaweed extract stimuli in plant science and agriculture (2011, background): “Positive responses include improved germination, root development, leaf quality, general plant vigor and resistance to pathogens (reviewed in Kahn et al. 2009).”
The Use of Biostimulants for Enhancing Nutrient Uptake (2015, background): “Liquefied SE is usually manufactured from Ascophyllum nodosum, a brown seaweed that is commonly found in the North Atlantic, although other species, such as Durvillaea antarctica, Durvillaea potatorum, Macrocystis pyrifera, and Ecklonia maxima are also used (Khan et al., 2009).”
Biostimulants Application in Horticultural Crops under Abiotic Stress Conditions (2019, background): “Many authors have observed that plant based biostimulants and seaweed extracts often increase the colour of leaves by stimulating chlorophyll biosynthesis or reducing its degradation [99,100].”
Plant Biostimulants: A Categorical Review, Their Implications for Row Crop Production, and Relation to Soil Health Indicators (2021, background): “The use of seaweed extracts has been extensively reviewed and reported to increase plant growth, nutrient uptake, and grain yield as a result of phytohormones within the product, mitigation of stresses, and/or upregulation of plant metabolism [24,25,29,30].”
A Commercial Extract of Brown Macroalga (Ascophyllum nodosum) Affects Yield and the Nutritional Quality of Spinach In Vitro (2013, background): “Extracts derived from the brown alga Ascophyllum nodosum (ANE) have been widely used in agriculture and horticulture as a complement to fertilizers because of their beneficial effects on crop production, nutrient uptake, stress resistance, and the quality of products after harvest (Abdel-Hafeez 2005”
Recent methods of drought stress tolerance in plants (2017, background): “Seaweed and seaweed extracts (SWEs) classified as plant biostimulants (Khan et al. 2009) are generally thought to contain trace amounts of macro- and micronutrient elements, amino acids, vitamins, cytokinins, auxins, abscisic acid-like compounds, and quaternary ammonium compounds (Stirk et al.”
Effect of liquid seaweed extracts on growth of tomato seedlings (Solanum lycopersicum L.) (2014, background): “These extracts are marketed as liquid biostimulants because a chemical analysis of seaweeds and their extracts has revealed the presence of a wide variety of plant growth-promoting substances such as auxins, cytokinins, and betaines (Khan et al. 2009).”
Plant- and Seaweed-Based Extracts Increase Yield but Differentially Modulate Nutritional Quality of Greenhouse Spinach through Biostimulant Action (2018, background): “The main components of commercial PHs are a mixture of free amino acids, oligo- and polypeptides sourced from animal or plant origins [11]; whereas commercial SWE, in particular the brown macro-algae (Ascophyllum nodosum and Ecklonia maxima), are important sources of polysaccharides (alginates, fuco”
Foliar application of liquid biofertilizer of brown alga Stoechospermum marginatum on growth, biochemical and yield of Solanum melongena (2015, background): “These extracts are marketed as liquid biofertilizers because the chemical analyses of seaweeds and their extracts have revealed the presence of a wide variety of plant growth-promoting substances such as auxins, cytokinins and betaines (Khan et al. 2009).”
