摘　　要：综述拮抗微生物诱导采后果蔬抗病性的机制。拮抗微生物能够诱导果蔬产生植物保卫素,提高果蔬防御酶如几丁质酶、β-1,3-葡聚糖酶、苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶的活性,并能够通过调节活性氧代谢和提高果蔬结构抗性,从而增强果蔬的抗病性。拮抗微生物诱导采后果蔬抗病性的机制研究将为生物防治技术在采后果蔬病害防治中的应用提供参考依据。Disease-resistant mechanism of post-harvest fruits and vegetables induced by antagonists has been reviewed.The antagonists improved resistance to disease in fruits and vegetables by improving the content of phyto alexi and the activities of defense enzymes such as chintinase（CHI）,β-1,3-glucanase,phenylalanine ammonia-lyase（PAL）,peroxidase（POD） and polyphenol oxidase（PPO）.The antagonists also regulated the active oxygen metabolism,and strengthened the resistance of organization structure in fruits and vegetables.These studies on disease-resistant mechanism induced by the antagonists will provide references for the application of biological technology for disease control in post-harvest fruits and vegetables.
