| 内容記述 | We studied nitrate uptake and nitrogen accumulation in cabbages grown in pots under shade. Cabbages at the head developing stage were covered by 50% or 90% black shadecloth and fed with 15^N-labeled potassium nitrate. Shading decreased the uptake of N derived from the nitrate feeding (Nf) relative to the unshaded control. In the outer leaves, shading increased the Nf content of the nitrate fraction and decreased those of the amino acid and insoluble-N fractions. In the heads, shading did not affect the Nf content of the nitrate fraction, but it decreased those of the amino acid and insoluble-N fractions. Shading increased the nitrate content in the outer leaves but had no effect in the heads. Shading decreased the activity of nitrate reductase (NR) in the outer leaves, especially in the upper position of those leaves, but did not affect NR activity in the heads, which was feeble compared with that in the outer leaves. These results suggest that shading has no effect on the accumulation of nitrate, but it diminishes the accumulation of assimilated N in the heads. In the upper position of the outer leaves, the involvement of NR activity in the accumulation of assimilated N indicates the importance of light conditions in this part to the quality of cabbage heads. | |||||||||||
