説明
The Germination characteristics of seeds, growth of seedlings in paddy-fields and controlling effect of some herbicides on seedlings of sea club rush were examined.<br>1) Germination of seeds were observed in paddy-fields (Table 1).<br>2) The seeds is covered with a hard seed coat, resulting in slow water absorption. However water absorption was enhanced by the cutting of the basal part of seed and digestion of the seed coat with sulfuric acid (Fig. 2).<br>3) The seed of sea club rush germinated under alternating temperatures in the light, and the germination was markedly promoted by the cutting of the basal part of the seed (Fig. 3).<br>4) Seeds which had been buried in paddy soil for two or three years exhibited a higher germination percentage than those buried for one year (Table 2).<br>5) The growth rate of the seedlings was significantly lower than that of the shoots which had emerged from the tubers (Table 3).<br>6) The emergence of seeds was effectively controlled with some herbicides (Table 4).
