Abstract


The objective of this study is to evaluate the influence of marine algae as biofertilizer on growth parameters and on the accumulation of chlorophyll "a" and proline in sunflower plants. Sunflower seeds are grown in medium containing green algae: Ulva Lactuca as biofertilizer and in two control media containing soil and soil with chemical fertilizer. After the 47th day of the growth, the highest growth parameters are found in the plants grown in the medium with seaweed. The highest rate of chlorophyll "a" was found in the leaves of these plants, while the roots of these plants have accumulated the lowest rate of proline. These results suggest that plants grown in media with seaweed were confronted with a low stress compared with those grown under control, which results in a better growth. Seaweed contributes to the best development of plants and also reduces the risk of biotic and abiotic stress and can be used as alternative to chemical fertilizers known to be harmful for health and the environment.
