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。
Volatiles produced by Bacillus subtilis Tpb55 inhibited sporulation,mycelial growth and pigment biosynthesis of Alternaria alternata,pathogen of tobacco brown spot.In closed experiment equipment, volatiles of Tpb55 showed 100%control efficiency against tobacco brown spot.Compared with control,volatiles of Tpb55 significantly increased plant height,leaf blade length,leaf blade width and fresh weight of tobacco.No obvious adverse effects on tobacco were observed.
