The water absorption quantity of the aquatic plant (Zizania latifolia) was experimentally evaluated. The weekly water absorption quantity per unit wet weight of aquatic plant was the largest in from July to August. The changes of the water absorption quantity for a long time and for a short time were affected by the temperature and the duration of sunshine, respectively. The growth rate of aquatic plant per unit water absorption weight was about 20 g (wet weight) /kg (water absorption weight) .
