Abstract
The symptomatology of the Wilt disease of coconuts in India has been briefly discussed, a study of which points to the possibility of this being a virus disease. Preliminary attempts at grafting in coconut failed. As a substitute to grafting a new technique, i.e., sap transfusion has been adopted for virus transmission trials and the method has been described in detail. This method in effect simulates an organic union between a diseased root scion and a healthy root stock. Of the two possible ways of effecting transfusion or sap from a diseased to a healthy tree, the one wherein the sap pumped up by a severed diseased root is transfused into the system of a healthy tree is more practicable. However, this method is not utilisable for feeding infective extracts of aerial parts of infected coconut palms or other hosts. Therefore, feeding extracts through tips of roots induced in boxes for the sake of convenience was attempted. The absorption of extracts through uncut roots being slow and selective, these were fed through cut ends of mature roots of healthy palms.
