Effect of ozone (O3) on stored seeds of common bean (Phaseolus vulgaris L.)

Abstract

The present work was carried out at the Laboratory of Insect Pathology of the Center for Agricultural Research (CIAP), located at the Universidad Central "Marta Abreu" de Las Villas, with the aim to evaluate the effect of the ozone (O3) treatment on the seed vigor of P. vulgaris. To determine the effect of the ozone on the seed vigor, a germination test, electrical conductivity test and emergency tray test were performed on two common bean varieties (BAT-304 and Delicias-364). Ozone did not affect the vigor of the seeds of the varieties BAT-304 and Delicias-364. The exposure time of P. vulgaris seeds to 150 ppm of O3 did not affect the parameters of germination speed and the percentage of germination of the seeds.
