摘要: 为挖掘对香蕉枯萎病具有良好防治效果的生防菌资源,本研究从森林土壤和蕉园土壤中分离得到45株真菌,采用平板对峙法筛选出9株对香蕉枯萎病菌具有较好抑制效果的生防潜力菌株,平板抑制率为64%以上,在扫描电镜下观察到6株真菌会使香蕉枯萎病菌出现菌丝皱缩干瘪、孢子畸形等现象,3株真菌对香蕉枯萎病菌的菌丝和孢子形态无影响。通过温室盆栽试验评价对香蕉枯萎病的防效,结果表明9株生防潜力菌株均具有显著的防控效果,其中菌株HH16、HH19和HH20对香蕉枯萎病的植株防控效果和球茎防控效果最好,防效均大于64%。经形态学和分子生物学鉴定,菌株BL01为钩状木霉Trichoderma hamatum、菌株BL02为螺旋木霉T.spirale、菌株BL03为李氏木霉T.lixii、菌株BL04为Pinicola木霉T.pinicola,菌株BL05为瑞士青霉Penicillium raistrickii、菌株BL08为布雷正青霉P.brefeldianum、菌株HH16为云南木霉T.yunnanense、菌株HH19为厚木霉T.crassu和菌株HH20为绿木霉T.virens。本研究将为香蕉枯萎病生防菌剂的开发应用提供理论依据和技术支持。

Abstract: To explore the biocontrol strains with good control effects on banana Fusarium wilt disease, forty five strains of fungi were isolated from forest soil and banana plantation soil in this study. Using the plate confrontation method, nine strains with good inhibitory effects on Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) were obtained. All of nine showed an inhibition rate exceeding 64%. Under the scanning electron microscope, it was observed that six strains caused Foc TR4 to exhibit morphological abnormalities, including shrunken and desiccated hyphae as well as deformed spores. However, the remaining three strains had no observable effect on Foc TR4 morphology. The greenhouse pot experiments were used to evaluate the control effect of 9 stains on banana Fusarium wilt disease, and the results showed that all nine strains had significant control effects. Strain HH16, HH19 and HH20 have the best control effect on banana Fusarium wilt disease, with the control efficacy greater than 64%. Morphological and molecular biological identification revealed the following results, strain BL01 as Trichoderma hamatum, BL02 as T. spirale, BL03 as T. lixii, BL04 as T. pinicola, BL05 as Penicillium raistrickii, BL08 as P. brefeldianum, HH16 as T. yunnanense, HH19 as T. crassum, and HH20 as T. virens. This study will provide theoretical basis and technical support for the development and application of biocontrol agents for banana Fusarium wilt disease.
