Abstract

QuitoMax® is a biologically active, biocompatible and biodegradable product based on chitosan. It has the ability to stimulate plant growth, yield and induce defensive mechanisms against pathogens. Regardless of its field of action, this product must be able to maintain its chemical characteristics during storage. The objectives of this work were to evaluate the chemical characteristics of QuitoMax® during storage and biological activity in tomato seedlings. The conductivity, pH and mass of soluble chitosan were determined as chemical characteristics. Seeds previously treated with QuitoMax® were evaluated for germination and morphoagronomic variables of tomato postures 25 days after planting. As results, there were no significant changes in conductivity, pH and mass of soluble chitosan in the period evaluated. Likewise, no differences were between the conserved product found and one newly produced when evaluating the germination and plants height. The results obtained show that the product maintains the chemical characteristics and biological activity at 270 days of conservation.
