ABSTRACT
This research was done in the Insect Pathology Laboratory of the Agricultural Research Center (CIAP) at Marta Abreu Central University of Las Villas. The goal was to determine the effect of the ozone (O3) treatment on the vigor of S. bicolor seeds (variety UDG-110). Germination tests, electrical conductivity test and seedling growth rate tests were conducted. The electrical conductivity was low in the treatment of 48 h. In the 72 h treatment, the conductivity was higher than in the other treatments; but it was not significantly different from the control. Root and shoot length parameters were not affected by ozone. Ozone was proved to enhance the germination percentage, but it does not affect the vigor of S. bicolor seeds.
