Abstract
Abstract BACKGROUND: Cryptococcus laurentii is a well‐known postharvest yeast antagonist. N 6 ‐benzyladenine (6‐BA), a cytokinin plant hormone, has a role in retarding ripening and senescence of harvested produce. This study was conducted to evaluate the efficacy of C. laurentii and 6‐BA in reducing the blue mould disease of apple fruit. RESULTS: The combination of C. laurentii with 6‐BA (20 µg mL −1 ) was more effective in suppressing the Penicillium expansum infection in apple fruit wounds than C. laurentii alone, although 6‐BA (20 µg mL −1 ) alone neither affected the growth of C. laurentii nor reduced the incidence of the blue mould disease in vivo . Moreover, treatment of apple fruit with C. laurentii and 6‐BA (20 µg mL −1 ) resulted in stimulation of superoxide dismutase activity but in inhibition of the increase in peroxidase activity. CONCLUSION: 6‐BA (20 µg mL −1 ) could enhance the efficacy of C. laurentii in reducing the postharvest blue mould disease of apple fruit, which offered great potential in minimizing the postharvest decay of apple fruit in an integrated pest management strategy.
