    (2025-02) Castro Nuñez Richard Johao; Leiva Mora Michel
    The research work had the objective to evaluate the effect of ozonized water as a disinfectant agent on the percentage of contamination and in vitro establishment in Physalis peruviana L. during the establishment phase. The trial analyzed different concentrations of ozonized water for the disinfection of explants of Physalis peruviana L. used concentrations of 1.2 and 3 ppm of ozonated water were used in an immersion time of 5 minutes. Results were obtained in which no concentration managed to eliminate microbial agents, giving a contamination percentage of 100% and an establishment of 0%. In the test in the results there was only fungal contamination such as Penicilium sp., Cladosporium sp., Fusarium sp. y Colletotrichum sp., no bacterial contamination was observed, suggesting that ozonated water may have a disinfectant effect on bacteria.
