The study was aimed to screen actinomycetes with good control effects on sugarcane red rot and enrich the resources of biocontrol bacteria for sugarcane red rot. JY53, WK29 and JR28 were screened from sugarcane rhizosphere soil, which showed superior antifungal effects against sugarcane red rot pathogen. They were identified as Streptomyces virginiae, S. iranensis and S. lavendulae, respectively. The antifungal rate of WK29 against six plant pathogens ranged from 68.41% to 78.22%. The antifungal rate of JY53 against five pathogens ranged from 58.66% to 72.85%. The inhibition rates of four plant pathogens by JR28 ranged from 27.69% to 60.15%. All the strains exhibited a certain broad-spectrum activity. Further exploration of the antifungal mechanism revealed that JY53 inhibited pathogen growth by producing β-glucanase, siderophore and volatile substances, while WK29 and JR28 inhibited pathogen growth by producing protease, β-glucanase, cellulase, siderophore and volatile substances. Pot experiment showed that after treatment with the bacterial solution of JY53, WK29 and JR28, the incidence indice of sugarcane red rot was 28.00, 25.33 and 22.67, respectively, significantly lower than 64.00 of the CK, and had a good growth promoting effect. This study indicates that actinomycetes JY53, WK29 and JR28, have certain effects on the prevention and control of sugarcane red rot disease, further enriching the resources of biocontrol bacteria for sugarcane red rot disease.

为筛选出对甘蔗赤腐病具有良好防治效果的放线菌,丰富甘蔗赤腐病的生防菌资源,本研究从甘蔗根际土壤中筛选得到JY53、WK29、JR28三株对甘蔗赤腐病菌抑菌效果较优的放线菌,经鉴定分别为弗吉尼亚链霉菌(Streptomyces virginiae)、伊朗链霉菌(S.iranensis)和淡紫灰链霉菌(S.lavendulae)。WK29对6种植物病原菌的抑菌率为68.41%~78.22%;JY53对5种病原菌的抑菌率为58.66%~72.85%;JR28对4种植物病原菌的抑菌率为27.69%~60.15%,3株菌均具有一定广谱性。进一步探究其抑菌机理发现,菌株JY53通过产β-葡聚糖酶、嗜铁素及挥发性物质抑制病原菌生长,菌株WK29、JR28则通过产蛋白酶、β-葡聚糖酶、纤维素酶、嗜铁素及挥发性物质抑制病原菌生长。盆栽试验表明,放线菌JY53、WK29、JR28菌液处理后,甘蔗赤腐病发病指数分别为28.00、25.33、22.67,显著低于CK的64.00,并且具有较好的促生长效果。本研究表明,JY53、WK29、JR28三株放线菌对甘蔗赤腐病具有一定防治效果,进一步丰富了甘蔗赤腐病生防菌资源。

为筛选出对甘蔗赤腐病具有良好防治效果的放线菌,丰富甘蔗赤腐病的生防菌资源,本研究从甘蔗根际土壤中筛选得到JY53、WK29、JR28三株对甘蔗赤腐病菌抑菌效果较优的放线菌,经鉴定分别为弗吉尼亚链霉菌(Streptomyces virginiae)、伊朗链霉菌(S.iranensis)和淡紫灰链霉菌(S.lavendulae)。WK29对6种植物病原菌的抑菌率为68.41%~78.22%;JY53对5种病原菌的抑菌率为58.66%~72.85%;JR28对4种植物病原菌的抑菌率为27.69%~60.15%,3株菌均具有一定广谱性。进一步探究其抑菌机理发现,菌株JY53通过产β-葡聚糖酶、嗜铁素及挥发性物质抑制病原菌生长,菌株WK29、JR28则通过产蛋白酶、β-葡聚糖酶、纤维素酶、嗜铁素及挥发性物质抑制病原菌生长。盆栽试验表明,放线菌JY53、WK29、JR28菌液处理后,甘蔗赤腐病发病指数分别为28.00、25.33、22.67,显著低于CK的64.00,并且具有较好的促生长效果。本研究表明,JY53、WK29、JR28三株放线菌对甘蔗赤腐病具有一定防治效果,进一步丰富了甘蔗赤腐病生防菌资源。

The study was aimed to screen actinomycetes with good control effects on sugarcane red rot and enrich the resources of biocontrol bacteria for sugarcane red rot. JY53, WK29 and JR28 were screened from sugarcane rhizosphere soil, which showed superior antifungal effects against sugarcane red rot pathogen. They were identified as Streptomyces virginiae, S. iranensis and S. lavendulae, respectively. The antifungal rate of WK29 against six plant pathogens ranged from 68.41% to 78.22%. The antifungal rate of JY53 against five pathogens ranged from 58.66% to 72.85%. The inhibition rates of four plant pathogens by JR28 ranged from 27.69% to 60.15%. All the strains exhibited a certain broad-spectrum activity. Further exploration of the antifungal mechanism revealed that JY53 inhibited pathogen growth by producing β-glucanase, siderophore and volatile substances, while WK29 and JR28 inhibited pathogen growth by producing protease, β-glucanase, cellulase, siderophore and volatile substances. Pot experiment showed that after treatment with the bacterial solution of JY53, WK29 and JR28, the incidence indice of sugarcane red rot was 28.00, 25.33 and 22.67, respectively, significantly lower than 64.00 of the CK, and had a good growth promoting effect. This study indicates that actinomycetes JY53, WK29 and JR28, have certain effects on the prevention and control of sugarcane red rot disease, further enriching the resources of biocontrol bacteria for sugarcane red rot disease.
