芒果炭疽病（Colletotrichum gloeosporioidoid）是芒果采后最重要的病害之一，常造成巨大的经济损失。研究了1-甲基环丙烯（1-MCP）对芒果采后炭疽病的防治效果及其作用机制。1-MCP诱导胶孢炭疽菌孢子产生活性氧（ROS），损伤线粒体，破坏质膜完整性，显著抑制孢子萌发和菌丝生长。1-MCP还降低了芒果果实腐烂率和由C. gloeosporioides引起的病斑扩展。本研究首次证实1-MCP可直接抑制芒果炭疽病菌孢子萌发和菌丝生长，从而抑制采后芒果炭疽病的发生。
Anthracnose caused byColletotrichum gloeosporioidesis one of the most important postharvest diseases in mango fruit, often causing huge economic losses. In this study, the effect of 1-methylcyclopropene (1-MCP) against anthracnose in postharvest mango fruit and the mechanisms involved were investigated. 1-MCP induced reactive oxygen species (ROS) generation, damaged the mitochondria and destroyed the integrity of plasma membrane of spores ofC.gloeosporioides, significantly suppressing spore germination and mycelial growth ofC.gloeosporioides. 1-MCP also decreased the decay incidence and lesion expansion of mango fruit caused byC.gloeosporioides. For the first time this study demonstrated that 1-MCP suppressed anthracnose of postharvest mango fruit by directly inhibiting spore germination and mycelial growth ofC.gloeosporioides, thus providing a promising strategy for disease control.
