薬剤と乾熱処理の組み合わせによるウリ科野菜の果実汚斑細菌病菌汚染種子の消毒

Abstract

A mixture of CuSO4 and acetic acid disinfested wax gourd seeds that had been infested with Acidovorax citrulli more effectively than did ascorbic acid, peroxyacetic acid or a mixture of oxytetracycline, streptomycin and CuSO4. Seeds of melon, cucumber and wax gourd were completely disinfested after a 60-min soak in the mixture followed by dry-heat at 75°C for 4 days without affecting germination. Seeds of brown seed squash, large seed squash and bottle gourd were disinfested by a 60-min soak in the mixture followed by dry-heat at 80°C for 4 days, which caused a small delay in germination. Any treatments of small or white seeds of squash that combined a soak in the chemical mixture with dry heat and effectively disinfested the seeds also inhibited germination.
