| Abstract: | Toxin-producing culture medium and culture time for Phomopsis asparagi were optimized, and the effect of the pathogen toxin on asparagus callus was investigated in the study. It was found that the toxin produced from culture for 12 days in the Fries medium showed the strongest inhibition effect on asparagus radicle. Toxin caused callus of ‘Apollo’, ‘Champion’ and ‘NJ987’ browning. Resistance of the callus of the three varieties to toxin could be induced by toxin treatment. Toxin concentration for resistant callus selection was 30%-40%. |
