摘要
灰霉葡萄孢(Botrytis cinerea)和交链孢(Alternaria sp.)是鲜食葡萄采后贮运中的主要病原菌,SO_2能有效地控制它们引起的鲜食葡萄的采后腐烂。作者分别设定50μl/L·1h、100μl/L·1h、200μl/L·0.5h、200μl/L·1h和对照5个处理,研究了不同剂量的SO_2对灰霉葡萄孢和交链孢的孢子、菌丝及所引起的腐烂的抑制作用。结果发现:各处理中200μl/L·1h的SO_2是抑制灰霉葡萄孢和交链孢的最佳剂量,但并不能彻底杀死灰霉葡萄孢和交链孢的孢子及菌丝,待SO_2消散后一定时间内孢子还可恢复萌发力。且在相同的剂量下,低浓度长时间的处理对孢子萌发的延缓效果优于高浓度短时间的处理。
Botrytis cinerea and Altemaria sp. are the major pathogens in the storage and transportation of postharvest table grape, sulfur dioxide can efficiently inhibit the decay caused by them. This work studies the inhibition of sulfur dioxide on Botrytis cinerea and Altemaria sp. with five treatments(50·l/L · 1h,100·l/L ·lh,200 /·l/L · 0. 5h,200·l/L · 1h and control ). The results showed that 200·l/L · 1h was the most efficient dosage, but it could not kill the spore and mycelium of Botrytis cinerea and Altemaria sp. thoroughly. They could recover the germinating activity after sulfur dioxide dissipated. And at the same dosage,the inhibitory effect of the treatment with low concentration and long time is better than with high concentration and short time in later stage.
