Abstract
Infection with the pathogenic root rot fungi (Rhizoctonia solani Kühn and Fusarium solani (Martins) Sacc.) to cucumber and squash increased peroxidase activity. The highest activity of peroxidase enzyme was detected in cucumber roots, while the lowest one was observed in squash roots. Infection also increased the polyphenol oxidase activity in the roots of both hosts. Inoculation with the pathogenic fungi and coating of seeds with plant growth promoting rhizomicroorganisms resulted in an increase in the percent of total phenol contents. Furthermore, the coating of seeds with plant growth promotings increased the plant roots content of Indol Acetic Acid (IAA) and Gibberellic Acid (GA3).
