Background. The interest in studying seaweed polysaccharidesas plant growth biostimulants is recent and has generally focused on seaweedliquid extracts for compounds content that have positive effect on plantdevelopment. Within these compounds are the carbohydrates such as alginate andfucoidan, among others. Goals. To evaluate the effect of crude fucoidan andalginate on seed germination and their growth-stimulating activity on seedlingof mung bean (Vigna radiata).
Methods. Fucoidan and alginate from Eisenia arborea andSargassum horridum at six different doses (0.6, 1.2, 2.5, 5, 10, and 20 mg m)were evaluated on seed germination and seedling growth of mung bean. Results.Alginate from both algae species in this study did not show a significanteffect on mung bean growth. Fucoidan from S. horridum produced thesignificant effect on mung bean growth by increasing root length (16.2%) andseedling total length (11.9%) at a concentration of 0.6 mg mL and an increase inthe dry weight of the seedling (31%) at a concentration of 20 mg mL?1.
Palabras clave: Eisenia arborea; polysaccharides; root length; Sargassum horridum; shoot length.
