Abstract:
The pear black spot pathogen （Alternaria kikuchiana Tanaka) was taken as teat strains,the mycelium growth rate determination method and pathogen spores germination ratio method were adopted,the effect of different concentrations of notoginseng,schisandrae and ginkgo extracts on antibacterial activity of bacterium of pear black spot were studied.The results showed that the three kinds of plant extracts on pear black rot showed different degrees of inhibitory activity,relative colony diameter decreased with the increasing of concentration of extracts,and the same extract on colony growth inhibition was different between different concentrations.In the concentration of 4 000 mg?L-1,the inhibition rate of the extract was 79 29%,while the concentration of 2 000,1 000 mg?L-1 excluded ethanol interference （adding or subtracting),and the inhibition rate was greater than 50 00%.The inhibitory rate of schisandra and gingko extract was only 4 000 mg?L-1,which was 52 78% and 50 56% respectively,while inhibition was not obvious at other concentrations.It showed that notoginseng extracts had higher inhibition activity with concentration of 4 000,2 000,1 000 mg?L-1.The EC50 of the extracts of the notoginseng,schisandrae and ginkgo were 524 40,3 196 44,3 558 51 mg?L-1 respectively.The spore germination rate was 28 16%,44 44% and 52 21% of notoginseng,schisandrae and ginkgo,respectively,at the concentration of 4 000 mg?L-1.The germination of the silk growth and pathogen spores of the pear black spot was inhibited by the treatment of the notoginseng extract.
