Evaluación del efecto del ozono sobre la incidencia de la enfermedad de la mancha anillada (Papaya ringspot virus-P, PRSV-P) en papaya (Carica papaya L.) en condiciones de invernadero.

Abstract

The present research was carried out in the laboratory and greenhouse of Plant Physiology of the Faculty of Technical Education for Development of the Catholic University of Santiago de Guayaquil. The objective was to determine the effect of ozone application before and after mechanical inoculation with PRSV-P in healthy papaya plants. The ozone dose treatments consisted of 2, 3, 4 and 5 ppm. The control treatments were related to papaya plants with sprinkling with water and without sprinkling. The data was analyzed with the probability test of X2 and indicates that, statistically, ozone did not exert an effect on PRSV-P because it showed favorable statistical significance due to the number of diseased plants obtained 20 days after inoculation with the virus. Currently, research continues to determine which doses and frequencies allow to affect the stability of the viral particles of PRSV-P.
