Biopriming of sweet pepper and tomato seeds with Ascophyllum nodosum

Organic agriculture has been growing in recent years; however, one of the limitations this area is treatment seeds with natural products and less aggressive to environment. Seed biopriming brown seaweed extract can be used improve physiological quality seeds. This study aimed evaluate effect seed Ascophyllum nodosum extracts (algae) on pepper tomato quality. Pepper All Big Alegria cultivars (cvs), Cereja Rio Grande cvs were used. The concentrations 0, 125, 250, 375 ppm. A completely randomized design a 2×4 factorial scheme was variables analyzed percentage germination; germination speed index; root shoot length; dry weight. Sweet at 125 ppm enhanced 16.5% for cv; but it did not benefit cv. A. as provided an increase 50% length growth although, had negative seedlings cv Tomato ppm, by 38 31% Nevertheless, provide higher levels germination. For cv, benefited approximately 1.04 cm larger than control. priming depended its concentration cultivar given that, different responses obtained, also due compounds extract.
