Resistance evaluation of Prunus davidiana var.potaninii rehd to crown gall disease
摘要
Abstract
In order to find out the resistance of Prunus davidiana var.potaninii Rehd to crown gall disease,the seedlings were used as materials to study the resistance of Prunus davidiana var.potaninii Rehd to A.tumefaciens and A.rhizogenes,applying the method of artificial inoculation.The results showed that Prunus davidiana var.potaninii Rehd was excellent germplasm resource resisting to crown gall disease.In 60 days after inoculation,the range of the maximum tumor diameter of inoculation seedlings to A.tumefaciens Conn was 0~10.1 mm with 2.7 mm on average,while it was 0~11.6 mm to A.rhizogenes Conn with 3.0 mm on average.According to the resistance evaluation standard of Prunus davidiana var.potaninii Rehd to Crown Gall Disease,it highly resisted to A.tumefaciens Conn and it was separated into 6 types,including being immune,highly resistant,moderately resistant,low resistant,susceptible and highly susceptible and their corresponding percentages were 35%,26%,19%,13%,6% and 1% respectively.There were also the same 6 types to A.rhizogenes Conn,and the corresponding percentages were 27%,35%,15%,13%,8% and 2% respectively.关键词
