 note = {Reproductive phenology of three edible agarophytes of Gracilaria, G. blodgettii Harvey, G. salicornia (C. Agardh) Dawson and G. vermiculophylla (Ohmi) Papenfuss, were studied from February 2002 to January 2003 in Okinawa Is., southern Japan. The maturation period, ratio of each reproductive phase and seasonal changes in the fresh weights of these species were determined. The tropical species, G. blodgettii, appeared in December and decreased through June. The ratio between tetrasporophytes and gametophytes was almost even except for the end of maturation period. Meanwhile, the temperate species, G. vermiculophylla, was confirmed during December to March. The ratio of tetrasporophytes and gametophytes was almost 2 to 1, although tetrasporophytes was more frequent during February and March. On the other hand, another tropical species, G. salicornia, was found throughout the year, but the reproductive plants were found only between December and June. Spermatangial plant of this species was confirmed for the first time in Japan. Congracilaria babae Yamamoto, an adelphoparasite that grows on G. salicornia, was confirmed only during June. The dominance of the three species in winter and spring in Okinawa Is. suggests that their growth is strongly influenced by seawater temperature.},
