摘　　要：采用生长速率法研究了肉桂C innam omum cassia活性成分肉桂醛、肉桂酸、肉桂酸乙酯对芒果炭疽病菌Colle-totrichum gloeosporioides抗药性菌株(ZJR)、芒果炭疽病菌敏感菌株(ZJS)和香蕉枯萎病菌Fusarium oxysporumf.sp.cubense的抑制作用.结果表明肉桂醛的抑制作用明显优于肉桂酸和肉桂酸乙酯.肉桂醛对ZJS、ZJR和香蕉枯萎病菌抑制的有效中浓度(EC50)分别为0.020 7、0.020 2和0.049 6 mg.mL-1.肉桂酸对ZJS、ZJR和香蕉枯萎病菌抑制的EC50分别为0.828、0.847和1.225 mg.mL-1.肉桂酸乙酯对ZJS、ZJR和香蕉枯萎病菌抑制的EC50分别为0.290 0、0.063 5和2.290 0 mg.mL-1.肉桂醛对ZJS、ZJR和香蕉枯萎病菌的最小抑制浓度分别为0.033 3、0.033 3和0.100 0 mg.mL-1.肉桂酸对ZJS、ZJR和香蕉枯萎病菌的最小抑制浓度分别为1.250、2.500和2.500 mg.mL-1;肉桂酸乙酯对ZJS的最小抑制浓度为0.500 mg.mL-1.The inhibition effects of Cinnamomum cassia active compounds on Colletotrichum gloeosporioides and Fusarium oxysporum f. sp. cubense were mensurated by growth rate method. The inhibition rates of cinnamaldehyde were more efficient to the control CoUetotrichum gloeosporioides and F. oxysporum f. sp. cubense than cinnamic acid and ethyl cinnamate. The EC50 of cinnamaldehyde against C. gloeosporioides sensitivity （ ZJS）, C. gloeosporioides resistance （ZJR） and Fusarium oxysporum f. sp. cubense were 0. 020 7,0. 020 2 and 0. 049 6 mg · mL^-1 respectively;0. 828,0. 847,1. 225 mg · mL^-1 for cinnamaldehyde respectively; and 0. 290 0,0. 063 5,2. 290 0 mg · mL^-1 for ethyl cinnamate respectively. The minimum inhibitory concentrations of cinnamaldehyde on C. gloeosporioides ZJS, C. gloeosporioides ZJR and Fusarium oxysporum f. sp. cubense were 0. 033 3,0. 033 3 ,and 0. 100 0 mg · mL^-1 respectively; 1. 250, 2. 500 and 2. 500 mg · mL^-1 for cinnamic acid respectively ; the minimum inhibitory concentration of ethyl cinnamate against C. gloeosporioides ZJS was 0. 500 mg · mL^-1.
