9月下旬，龟浦湖江崎湾滨海带沙质沉积物上生长的水仙的季节最大生物量仅为47.6g干重·Em-2。叶片寿命为28天，200天的生物量周转率为3.4，与已报道的漂浮叶植物相当，远高于其他草本植物。年单位面积净生产量估计为182g干重·Em-2。这一数值小于报道的同一地点浮游植物和生长在该湖其他地区的浮游植物的数值。
The seasonal maximum biomass of Nymphoides peltata growing on sandy sediment at the littoral zone of Edosaki-iri Bay in Lake Kasumigaura was only 47.6 g dry weight •E m-2 in late September. Leaf life span was 28 days and thus biomass turnover rate was estimated as 3.4 for 200 days, comparable with those reported for floatingleaved plants and much higher than other herbaceous plants. The yearly net production per unit ground area was estimated at 182 g dry weight •E m-2. This value is smaller than that reported for phytoplankton at the same site and for f loating-leaved plants growing at other regions of this lake.
