【摘要】 枯草芽孢杆菌Tpb55菌株挥发性代谢产物对烟草赤星病菌菌丝生长、孢子产生具有抑制作用,并延缓黑色素的产生。在相对封闭的试验条件下,Tpb55菌株挥发性物,对烟草赤星病的防治效果达100%。促生效应测定结果表明,Tpb55挥发物对烟草生长无明显毒害作用,且株高、叶长、叶宽和鲜重较显著增加。结果表明,Tpb55挥发性代谢产物具良好的抑菌、促生和防病作用,是寻找抗菌、促生物质新的途径。更多还原

【Abstract】 Volatiles produced by Bacillus subtilis Tpb55 strain inhibited sporulation, mycelial growth and pigment biosynthesis of Alternaria alternata, pathogen of tobacco brown spot. Under enclosed experiment condition, volatiles of Tpb55 showed 100% efficiency to control tobacco brown spot. Compared with control, volatiles of Tpb55 significantly increased the plant hight, leaf blade length, leaf blade width and fresh weight of tobacco. And no obvious adverse effect on tobacco was found. Results from this research showed that volatiles produced by Tpb55 had good effects of pathogen inhibition, disease control and tobacco growth enhancement. Bacterial volatiles provide a new source of compounds with antibiotic and growth-promoting features.更多还原
