Abstract

Methods of disinfecting cucumber seeds that originate from plants infected by cucumber green mottle mosaic tobamovirus (CGMMV).

Abstract

Cucumber seeds harvested from CGMMV-infected plants grown in Poland during 1997-98 were treated with: 1% hydrochloric acid, 0.6% acetic acid, 0.3% sodium hypochlorite, 1% calcium hypochlorite, 1% sodium p-toluenesulfochloramine, 5% calcium oxide, 1% sodium hydrate, 10% sodium phosphate, an experimental seed treatment, and seed thermotherapy in 70°C during 3 days. The heat treatment was efficient with fresh seeds only, while 2-year-old seeds almost totally lost their ability to germinate. Optimum concentrations for disinfection purposes were as follow: 0.5-1.0% hydrochloric acid, 0.3-0.5% sodium hypochlorite, 10% sodium phosphate.
