摘要:
探讨了壳寡糖对烟草赤星病病原菌(链格孢菌)菌丝生长、孢子萌发、产孢量的影响,并研究了温度和pH值对壳寡糖抑菌作用的影响.结果表明:浓度为15 g/L的壳寡糖在48 h对烟草赤星病病原菌菌丝生长的抑制率为94.74%.壳寡糖抑制病原菌孢子萌发能力强于抑制病原菌菌丝生长,浓度为2.5 g/L的壳寡糖对病原菌孢子萌发抑制率达到100%.质量浓度为10 g/L的壳寡糖在144 h对链格孢菌产孢抑制率为69.7%.壳寡糖的抑菌效果具有良好的热稳定性,pH值对抑菌效果影响较大,质量浓度为15 g/L的壳寡糖在48 h、培养基pH为4时对菌丝生长抑制率达到100%,培养基pH为7时抑制率为62.26%.
Abstract:
The effects of oligochitosan on mycelial growth, spore germination and sporulation of Alternaria alternate of tobacco were explored, and the effects of temperature and pH values to the antibacterial effect of oligochitosan were also studied. The results show that when the concentration of oligochitosan is 15 g/L, the inhibition rate of mycelial growth to mycelial growth of A. alternate is 94.74% in 48 h, and when the concentration of oligochitosan is only 2.5 g/L, the inhibition rate to spore germination of A. alternate is 100%. When the concentration of oligochitosan is 10 g/L, the inhibition rate of sporulation of A. alternate is 69.7% in 144 h. The antibacterial effect of oligochitosan has a good thermal stability. The pH values show great influence to the antibacterial effect of oligochitosan. When the concentration of oligochitosan is 15 g/L, the inhibiton rates of mycelial growth of A. alternate is 100% with the medium pH 4 in 48 h, and 62.26% with the medium pH 7 in 48 h.
