| Research Abstract |
Lycoris radiata kept ability of taking up nitrogen all year round. Nitrogen uptake in summer facilitated growth in the following growing season. Nitrogen uptake in autumn contributed to higher photosynthetic potential of leaves but had no effect on growth of the season. Nitrogen taken up in winter contributed neither to photosynthesis nor growth, but was stored in the bulb and hence considered to contribute to growth of the next season.
