Obtaining quality seedlings from vegetable species is essential for field crop productivity. In most cases, the low seed germination capacity is an impediment to achieving this goal. Treating seeds with different solutions of natural compounds or suspensions of beneficial microorganisms for improving seed germination parameters is an ecological and viable solution in the field. The present study presents results obtained in vitro regarding the effect of seed treatments with Trichoderma strains and salicylic acid on germination parameters (percentage and rate) for three species of vegetables, beans, onions and peppers. The experiments confirmed the positive effect of both salicylic acid and Trichoderma treatments on the germination percentage and rate for seeds of all species studied compared to the control variants. Trichoderma spores treatments with 1x107 spore/mL concentration gave the best results.
