The problematical nature of the exocortis disease of trifoliage orange – whether it is of a virus nature transmitted to the trifoliate stock by an infected scion which in itself may show no symptoms, whether it is transmitted by an insect vector or whether it is genetic and an inherent character of the root-stock–is under further study in an experimental planting at Riverside.
