Effect of applying a biostimulant containing seaweed and amino acids on the content of fiber fractions in three soybean cultivars

Abstract

The experiment was conducted in the years 2014-2016 with the aim to evaluate the influence of a biostimulant based on seaweed and amino acids on the content of neutral and acid detergent fiber, lignin, cellulose and hemicellulose in three cultivars of soybean. In the vegetative season, 0.7% and 1.0% solutions of the biostimulant were used in single and double spraying. Based on the determined fiber fraction contents it was evaluated whether treating soybean with the biostimulant may enhance the quality of forages obtained from it. It was found that the level of fiber fractions and contents of hemicellulose and cellulose were influenced by biostimulant application. Differences in the content of fiber fractions resulted from the number of biostimulant doses and its concentration. Mavka cultivar treated with Fylloton was characterized by the highest mean content of fiber fraction. Evaluation of the forage quality indexes demonstrated that biostimulant use caused their reduction, and the highest values were found for Annushka cultivar.

Changes in Biochemistry and Yield in Response to Biostimulants Applied in Bean (Phaseolus vulgaris L.)

“…The pathways are also associated with the synthesis of secondary metabolites, including phenolic compounds, which play an important role in protecting plants against stress factors. In turn, a frequent indicator of plant resistance to biotic factors is the content of phenolic compounds, which are precursors to more complex phenolic structures, such as flavonoids and lignins [60,111]. The presence of bioactive compounds in biostimulants, including phytohormones, amino acids, protein, and phenols, is responsible for the physiological response of plants treated with these preparations [56,112,113].…”

“…The beneficial effect of biostimulants with seaweed extracts or amino acids on plant growth and development, and on the quantity and quality of the yield, regardless of its developmental stage, was confirmed in numerous studies [13,34,35,[39][40][41][57][58][59][60][61][62]. An interesting solution is to combine these two components in a single preparation, as in the case of the Fylloton biostimulant (Biolchim Poland), which contains the extract of Ascophyllum nodosum (L.) Le Jolis, as well as vegetal amino acids.…”

“…The use of biostimulants that positively affect the metabolic processes occurring in the plant, especially in the time of climate change, which causes stress factors for this sensitive plant, can be one of the elements contributing to the improvement in the quantity and quality of bean yield. Plant response to the biostimulant often depends on the variety, as demonstrated in earlier studies [15,39,59,60]. There are also no reports regarding the reaction of two-colored coat seed of bean to treatment with biostimulants.…”

Morphological and Biochemical Responses of Glycine max (L.) Merr. to the Use of Seaweed Extract

“…Today, they are believed to play a significant role in plant protection against adverse factors [130]. The most common indicator of plants resistance to biotic factors is the content of phenolic compounds [131], which are precursors of more complex phenolic structures, like flavonoids or lignins [132].…”

Evaluation of the Effects of Allelopathic Aqueous Plant Extracts, as Potential Preparations for Seed Dressing, on the Modulation of Cauliflower Seed Germination

“…The secondary metabolites exhibiting allelopathic potential, referred to as allelochemicals, have been a focus of interest for many researchers over recent years [8][9][10][11]. Equally great attention has been paid to the phenomenon of allelopathy, since evidence has been found for its significant role in regulating the growth of plants and the development of agricultural systems, including the quality and size of the crop yield produced [1,2,[12][13][14].…”
