Abstract

The study was developed in order to determine the effect of aqueous extracts of Helianthus annuus Lin on Solanum lycopersicum Lin growth. Roots and leaves samples of sunflower plants were collected from a policulture system located in a mountainous agroecosystem and their effects. These effects were evaluated on certified tomato seeds about germination, radicle and hypocotyl length. Nine treatments with four replicates were established in Petri plates. The extracts of sunflower from roots, and from leaves, at 15, 30 and 45 and at 75 and 90 days of development, respectively, inhibited tomato seed germination. Sunflower root extracts at 75 and 90 days of development stimulated tomato radical and hypocotyl growth. These results showed that sunflower plant produces chemical substances inhibiting tomato growth specifically the radicle and the hypocotyl in the earlier 45 days of growth after germination, and it is not recommended the association of these two crops simultaneously.
