The phenolics, laminarin, and fucose compounds present in seaweed extracts at lower concentrations contributed significantly to increasing the tolerance to Fe deficiency in tomato plants.
The beneficial effects of seaweed extracts have been related to plant growth regulators present in seaweeds. However, algae extracts comprise other organic compounds such as phenols, mannitol, alginates, laminarins, and fucoidans that may have a relevant role regarding abiotic stress tolerance due to nutrient deficiency. Therefore, we evaluated the individual effect of these organic compounds in a range of concentrations on the mitigation of Fe deficiency in tomato plants. Germination and plant growth promotion, root morphology, chlorophyll content, and antioxidant activity were determined. Results showed that the lowest concentration of phenolics, laminarin, and fucose compounds contributed to increasing the tolerance to Fe deficiency in tomato plants.
