摘要
研究了GRAS物质钼酸铵和焦亚硫酸钠处理对苹果青霉病和黑斑病的控制,结果表明在离体条件下,钼酸铵和焦亚硫酸钠均能抑制Penicillium expansum和Alternaria alternate菌落的生长,其中7.5 g/L钼酸铵、0.3 g/L焦亚硫酸钠抑制效果最佳,其抑菌率分别达到78.7%、72.7%、81.3%、56.3%。体内试验表明,钼酸铵和焦亚硫酸钠对损伤接种苹果的青霉病和黑斑病也有一定的控制作用,其中7.5 g/L的钼酸铵对苹果青霉病的抑制效果最佳,0.25 g/L的焦亚硫酸钠对苹果黑斑病抑制效果最佳。
Effect of different concentration of ammonium molybdate and sodium metabisulphite treatment on blue mold and black spot of postharvest apple were studied. The results showed that ammonium molybdate and sodium metabisulphite could inhibite significantly the mycelium growth of Penicillium expansum and Alternaria alternate, 7.5 g/L ammonium molybdate, 0.3 g/L sodium metabisulphite gave the best control, their inhibition percentage was 78.7%, 72.7% and 81.3%, 56.3% respectively. In vivo test showed that ammonium molybdate and sodium metabisulphite also inhibited the development of blue mold and black spot, 7.5 g/L ammonium molybdate inhibited the development of blue mold and 0.25 g/L sodium metabisulphite inhibited the development of black spot are significantly .
