Carbohydrate containing biopolymers derived from brown algae as promoters of growth, development and productivity of agricultural crops

Marine organisms are a rich resource of pharmaceutical active compounds which have a wide range of biological activity, including anticoagulant action, immunomodulating action, anti-tumor activity, antibacterial, antifungal and antiviral, antiinflammatory, antioxidant, lipid-corrective activity etc. Antivir, Laminaran and Fucoidan derived from Laminaria cichorioides were tested in field conditions, as stimulants of growth and development of barley (Hordeum vulgare L.), wheat (Triticum aestivum L.) and buckwheat (Fagopyrum esculentum Moench). Research shows that stimulating effect depends on chemical structure of polysaccharides and on plant species. Antivir, Laminaran and Fucoidan at different concentrations stimulate growth, productivity and morphological traits (plant height, ear length, productive bushiness and others) of barley, wheat and buckwheat. Carbohydrate containing biopolymers derived from the sea algae effect differently upon rutin content in seeds and stems of buckwheat.
