Study on the antimicrobial effect of the extracts of Kiwi Fruit roots

The aim was to research the antimicrobial effect of the extracts of Kiwi Fruit roots with different solvents on the common plant microbes. The bacteria cake method was used to study the antimicrobial capability of Kiwi Fruit roots. The extracts have anti-bacterial action on Rhixoctonia cerealis, Fusarium gram inearum, Rhizoctonia solani and Setosphaeria turcica, especially the extract from distilled water has the strongest anti-bacterial action on Rhixoctonia cerealis and Fusarium gram inearum, the extract from ether has the strongest anti-bacterial action on Fusarium gram inearum, the MIC all were 10 mg/ml The extracts had different antimicrobial effect when pH value was from 5 to 8. The extracts of Kiwi Fruit roots could inhibit the 4 pathogenic microorganism, and the antibacterial activity was affected by pH value greatly.
