甜瓜镰刀菌腐烂病是甜瓜采后的一种常见病、多发病，可导致甜瓜品质劣变和新茄醇（NEO）污染。控制收获后腐烂和减少近地物体污染的新战略至关重要。研究了乙酰水杨酸（阿萨）处理对黄瓜枯萎病菌（Fusarium sulphureum）生长的影响，以及对接种镰刀菌的果实腐烂和NEO积累的影响。研究了维沃韦雷中的硫脲。结果表明，阿萨对F.活体检测结果表明，3.2 mg/mL ASA处理后6 d和8 d，能显著抑制镰刀菌腐烂病的发生和NEO的积累。同时，参与NEO生物合成的Trigene表达在治疗后下调。综上所述，阿萨处理不仅通过抑制F.而通过抑制NEO的生物合成途径减少了NEO的积累。
Fusarium rot of muskmelon is a common and frequently-occurring postharvest disease, which leads to quality deterioration and neosolaniol (NEO) contamination. New strategies to control postharvest decay and reduce NEO contamination are of paramount importance. The effects of acetylsalicylic acid (ASA) treatment on the growth ofFusarium sulphureumin vitro, and Fusarium rot development and NEO accumulation in fruits inoculated withF. sulphureum in vivowere investigated. The results showed that ASA inhibited the growth ofF. sulphureum, evident morphological and major cellular changes were observed under the microscope.In vivotesting showed that 3.2 mg/mL ASA significantly suppressed Fusarium rot development and NEO accumulation after 6 and 8 d of pathogen inoculation. Meanwhile,Trigene expressions involved in NEO biosynthesis were down-regulated after treatment. Taken together, ASA treatment not only reduced Fusarium rot development by inhibiting the growth ofF. sulphureum, but decreased NEO accumulation by suppressing NEO biosynthesis pathway.
