Abstract

More than 10 strains of antagonists which can effectively control postharvest diseases of fruits were screened out from antagonists stored or isolated from surface and wound of peach fruits. Results showed that five stored antagonists (Burkholderia cepacia, Candida guiliermondii, Kloeckera apiculata, Debaryomyces han-senii, Bacillus subtilis) could effectively inhibit brown rot of sweet cherry fruit, among which Bacillus subtilis and Candida guiliermondii could entirely inhibit the disease. Candida guiliermondii and Kloeckera apiculata provided effective control of rhizopus rot of postharvest stone fruits. Cryptococcus albidus (Saito) Skinner and Trichosporon sp., both isolated from surface of peach fruits, could control gray mold and blue mold of apple fruits; Pichia membranefaciens hansen, isolated from wounds of peach fruits, inhibited rhizopus rot of stone fruit well. Among the bacterial isolated, B8 greatly inhibited rhizopus rot and brown rot, while Bw6 and Bw7 prevented brown rot and Bw10 could also significantly inhibit rhizopus rot.
