Recently, many farmers were suffering from poor flowering and reduced yield of 'Shiranuhi' mandarin in Jeju Island, Korea. In the current study, it was assumed to be related to outbreak of scion root and studies were carried out to find out the effect of outbreak of scion root on the C/N ratio, fruit quality and yield of 'Shiranuhi' mandarin hybrid. This study consisted of control (normal plant) and scion root (plant with scion root) of 'Shiranuhi' mandarin with five repetitions in a RBD and it showed that C/N ratio of old leaves was significantly reduced in trees containing scion roots compared with controls. Additionally, flowering, fruit weight and soluble solid contents of scion rooted plants were significantly reduced, but there was no difference in acid contents and colouring of fruits. Moreover, the yield of 'Shiranuhi' mandarin with scion rooting was severely reduced compared with controls.
