Viability of using organic substrates according to toxicity tests and the antioxidant activities of tomato seeds and seedlings

Abstract Plant growth can be directly influenced by the physical, chemical, and biological characteristics of their substrates. We tested the viability of using alternative substrates derived from agroindustrial residues by evaluating their effects on tomato (Solanum lycopersicum L.) germination and...
