Effects of SuperFifty seaweeds extract on tomato seed germination parameters, on roots and shoots length was investigated at the Plant Physiology Laboratory from University of Pitesti. The seeds of tomato were soaked in the solutions of seaweed extract in seven experimental variants. Experimental variants include seeds germinated on filter paper wetted with 1:1000 and 5:1000 dilutions of seaweeds extract (V2 and V3). Also, the variants include tomatoes seeds soaked for 24 hours in diluted seaweeds extract (V4 and V5), and tomatoes seeds soaked for 1 minute in diluted seaweeds extract (V6 and V7). Control variant represent tomatoes seeds germinated on filter paper wetted with distilled water (V1). Tomato seeds soaked for 1 minute in 1:1000 dilution of seaweeds extract SuperFifty showed the germinative energy higher than control (64,44%, p<0.05). Soaking the tomato seeds for 24 hours in diluted 5:1000 seaweeds extract SuperFifty produced a stimulation of the growth of roots and shoots of tomato seedlings. For the same variant, germinative energy and germination rate were not significantly affected.
