Abstract
Radioactive KH,PO4 was fed to coconut leaves and palms under laboratory and field conditions. In healthy palms the absorption of phosphorus by roots and Us accumulation In spindle and first fully opened leaves was found to be significantly higher till 9th hr as compared to that of diseased palms, but at later stages the reverse pattern was observed. The time required for 12P to reach the spindle (top-most leaf) situated at 9.5 m height In both diseased and healthy palm was found to be 3 hr only. In contrast to the leaves, the activity of P differed insignificantly in stem and roots of healthy and diseased palms and also the native P remained higher In the stem and roots of former palms as compared to latter. The analysis of total and different fractions of phosphorus and entry of P in the different forms of organic phosphorus indicated that although total P was more in the case of diseased palms but the organic phosphorus especially the nucleic acid P was significantly less as compared to healthy ones. This revealed less utilization of absorbed P in the synthesis of P-constituted organic substances in diseased palms.
