摘要:

为研究肉桂醛对番茄采后灰霉病的抑制作用及其对番茄果实品质的影响,在离体条件下分别研究肉桂醛对
灰葡萄孢菌菌丝生长、孢子萌发的抑制作用,采用人工活体接种法研究肉桂醛对番茄果实灰霉病斑的控制作用,及
其对番茄自然发病果实的品质的影响。结果表明,肉桂醛对灰葡萄孢菌的菌丝生长和孢子萌发均有较好的抑制作
用,对菌丝生长的EC50值为95.6 μg/mL,质量浓度为60 μg/mL时对孢子萌发抑制率为100%;活体条件下肉桂醛能够
有效地抑制番茄果实采后灰霉病病斑的扩展,以4 000 μg/mL效果最好,且在此质量浓度条件下,对于降低果实质
量损失率,维持番茄硬度、可溶性固形物、可滴定酸和VC含量均具有较好的效果。4 000 μg/mL肉桂醛处理能够有
效地控制番茄采后灰霉病的发生及延长其保鲜期。

Abstract:

In order to study the inhibitory effect of cinnamaldehyde on postharvest gray mold and its effect on quality
maintenance of tomato fruits, the inhibitory effect of the antimicrobial compound on spore germination and mycelial growth
of Botrytis cinerea cultured under detached conditions was investigated as well as the suppressive effect on the development
of blue gray lesions by artificial inoculation and the effect on the quality of naturally infected fruits. The results showed
that cinnamaldehyde treatment was significantly effectives against spore germination and mycelial growth of Botrytis
cinerea. The EC50 was 95.6 μg/mL in growth inhibition assays, and the spore germination was completely inhibited by 60 μg/mL
cinnamaldehyde. Cinnamaldehyde treatment also suppressed the development of postharvest blue gray lesions in tomato fruits and
4 000 μg/mL was the most effective concentration. The fruits maintained lower weight loss and higher hardness, total soluble solids
(TSS), titratable acid (TA) and ascorbic acid content at this concentration. This study indicates that cinnamaldehyde treatment at
4 000 μg/mL can effectively control postharvest gray mold and prolong the shelf life of tomato fruits.
