摘　　要：研究了丁香精油以及丁香精油-壳聚糖复合物对几种水果采后腐烂的主要致病真菌灰霉菌、链格孢,青霉菌、浆孢菌的孢子萌发和菌丝生长的抑制效应,确定其最低抑菌浓度和最低杀菌浓度。结果表明,丁香精油对供试病原菌均有较强的抑制效果,10μL/mL丁香油对4种菌菌丝生长和孢子萌发的抑制率达到85%以上。丁香油-壳聚糖复合物溶液在10μL/mL时(含丁香油有效成分5μL/mL)对4种菌菌丝生长和孢子萌发的抑制率在80%以上,而5μL/mL丁香油对其菌丝生长和孢子萌发的抑制率大都在80%以下,复合物的抑菌效应比含有相同有效浓度的丁香精油抑菌效应有明显提高。The inhibitory efficacy of clove oil and its combination with chitosan to spore germination and hyphal growth of several postharvest fungi, Botrytis cinerea , Alternarea alternat , Penicillium citrinum and Emericella nidulans was determined in this study, and the minimal inhibitory concentration （MIC） and minimal bactericidal concentration （MBC） were also tested. The results showed that clove oil has a strong inhibitory effect on postharvest pathogens. The inhibition rates of 10μL/mL clove oil to spore germination and hyphal growth of the four pathogens were all higher than 85%. The efficacy of clove oil in combination with chitosan was higher than 80% （containing 5μL/mL effective ingredient of clove oil）. But the inhibition rate of 5μL/mL clove oil alone to spore germination and hyphal growth of the four pathogens was lower than 80%. Therefore, the inhibitory efficacy of clove oil in combination with ehitosan was significantly higher than that of clove oil alone at the same effective concentration.
