摘要

With five strains of plant pathogenic fungus Exserohilum turcicum Pass. as test material, carbendazim and chlorothalonil as bacteriostats for compare, the bacteriostasis of silver nanoparticles on the growth of mycelium, the spore germination, as well as the inhibition zone and conductivity was studied. The results show: the bacteriostatic effect of silver nanoparticles is all significantly better than blank control, indicating that silver nanoparticles has better bacteriostatic effect on E. turcicum Pass. And there is an interspecific difference for silver nanoparticles's bacteriostatic effect on the five strains, the bacteriostatic effect of the strain 85-3 is better than 85-1, 85-2, 85-4 and H15. In the comparison among silver nanoparticles, carbendazim and chlorothalonil, the latter two have no significant difference in their bacteriostatic effect, but they are better than silver nanoparticles. Silver nanoparticles's bacteriostatic effect is achieved by changing the permeability of the cytomembrane.

Turcicum Pass具有更好的抑菌作用。并且存在对五种菌株的银纳米粒子的抑菌作用的差异,菌株85-3的抑菌效果优于85-1,85-2,85-4和H15。在银纳米粒子,碳纳西姆和氯洛尼洛尼核糖中的比较中,后两者对其抑菌效果没有显着差异,但它们比银纳米颗粒更好。通过改变细胞膜的渗透性来实现银纳米颗粒的抑菌效果。
