| 内容記述 | The characteristics of nitrate uptake and nitrogen distribution were studied in cabbage (Brassica oleracea L. var. capitata) using the 15^N tracer experiment. The 15^N labeled potassium nitrate was applied to pot-grown cabbage plants at the head-developing stage. The N derived from the applied nitrate (Nf) was mostly incorporated into the vegetative leaves (VL) immedi-ately after application, but the Nf amount in the VL decreased afterward. The Nf amount in the head leaves (HL) increased throughout the experiment. In the VL, most of the incorporated Nf was observed in the nitrate fraction immediately after application. Then, the Nf concentration in the nitrate fraction decreased, while those in the amino acid and insoluble fractions increased. The Nf distribution rate in the nitrate fraction was higher in the lower parts of the VL than in the upper parts. In the HL, as with the VL, most of the incorporated Nf was observed in the nitrate fraction immediately after application. Then, the Nf concentrations in the amino acid and insoluble fractions increased considerably, although the nitrate reductase activity of the HL was one-tenth lower than that of the VL. The increases in Nf concentrations in the these fractions was greater in the inner part of the VL than in the outer part. These results suggest that in the cabbage at the head developing stage there was an accumulation of reduced nitrogen in the HL that depended largely on nitrogen translocation from the VL ; nitrate is incorporated directly into the HL from the roots. | |||||||||||
