Abstract:
From 2016 to 2017,taking ripe rot kiwifruit collected from planting area in Guizhou Province Liupanshui city as raw material,and then the pathogens and pathogenicity differences were studied by pathogen isolation,pathogen identification,and pathogenicity identification in order to supply references for ripe rot prevention.The results showed that 23 pathogenic bacteria were isolated and obtained accession numbers MF498063-498065,MG775300-775302 and MG775283-775299,respectively;the isolated pathogens were Botryosphaeria sp.,Alternaria sp.,Phomopsis sp.,Neofusicoccum sp.and Diaporthe sp.,the detection rates of respective genus were 30.4%,30.4%,26.1%,8.7% and 4.4%;23 pathogenic bacteria experienced cluster analysis were divided into weak pathogenicity(26.09%),moderate pathogenicity(39.13%),strong pathogenicity(26.09%) and stronger pathogenicity(8.69%).
