摘要: 为研究葡萄汁有孢汉逊酵母(Hanseniaspora uvarum)挥发物单体对草莓灰霉病的防治作用,研究了21 种挥发物单体离体条件下对灰葡萄孢的抑制作用,以及活体条件下3-羟基己酸乙酯、癸酸乙酯、桂皮醛和辛酸乙酯对草莓果实灰霉病的防治作用。结果表明:除月桂酸外,其余20 种单体均对灰葡萄孢菌丝生长和孢子萌发有抑制作用,其中桂皮醛剂量为62.5 μL/L时完全抑制菌丝生长,625 μL/L时可以完全抑制孢子萌发;活体条件下,4 种单体均能有效地抑制草莓果实采后灰霉病的发生,保持草莓色泽,延缓草莓可溶性固形物质量分数、可滴定酸质量分数、硬度等质构特性的下降,其中桂皮醛防治草莓灰霉病效果最好,具有商业开发前景。

Abstract: The effects of 21 volatile monomers from Hanseniaspora uvarum on spore germination and mycelial growth of the gray mold Botrytis cinerea were evaluated under in vitro conditions. This study also determined the efficacy of ethyl 3-hydroxybhexanoate, ethyl caprate, cinnamaldehyde and ethyl caprylate to control postharvest gray mold in strawberries. The results showed that all volatile monomers except lauric acid inhibited mycelial growth and spore germination of Botrytis cinerea, which was completely inhibited by cinnamaldehyde at 62.5 and 625 μL/L, respectively. All four volatile monomers tested suppressed the occurrence of gray mold, maintained the color, and inhibited the decrease of total soluble solids, titratable acid and hardness of postharvest strawberry. Among these, cinnamaldehyde had the potential to be used as a biocontrol agent against strawberry gray mold disease with good commercial prospects.
