It is clear that the capacity and activity of the antioxidative defence system are important in limiting oxidative damage and in destroying active oxygen species that are produced in excess of those normally required for metabolism. Carbohydrate Res 310:203–210. An experiment entitled, Studies on effect of herbal extract Samved Fugall (CO2) Extracts of vari-, as an AM fungus growth promoter (Kuwada and others, methanol extracts of brown algae fractionated by flash, chromatography promoted in vitro AM hyphal growth as, well as improved root colonization by AM fungi on trifo-, Indigenous AM fungi demonstrated a 27% improvement in, root colonization, while spore number was increased about, 21% over the controls when liquid fertilizer containing, system in a citrus orchard (Kuwada and others, (25% MeOH eluates) of red and green algae considerably, showed that application of the 25% MeOH eluates of red, and green algal extracts to roots of papaya (. Controls included untreated cuttings. The implementation of agronomic activities, based on the use of biostimulants, is an important element of agroecological practices.

Atlantic Food and Horticulture Research Centre. This article provides a comprehensive review of the effect of various seaweed species and seaweed products on plant growth and development with an emphasis on the use of this renewable bioresource in sustainable agricultural systems. ably encourage flowering by initiating robust plant growth. The achieved soil remediation by dried seaweeds might be due to their efficient metal biosorption capacity due to the existence of active functional groups on their cell wall surfaces. industrial raw materials, and in therapeutic and botanical applications for centuries. For seaweeds mixture-treated soil, cultivated radish roots were able to phyto-extract Cd, Cu, Cr, and Ni from the soil (bioaccumulation factor values > 1) of 7.45, 1.18, 3.13, and 26.6, respectively.

Several authors associated positive effects of ANE to higher chlorophyll concentration, nutrient uptake and nutrient use efficiency.
