 note = {application/pdf, Seasonal variation of the three reproductive thalli of Gracilaria blodgetii agarophyte were collected monthly from tropical waters of Okinawa, Japan. Majority of thr plants from the natural population were tetrasporic plants (43.82%) which could be explained by the enhanced survival of carpospore germlings; 32.04% of plants were female while the remaining 24.14% consisted of sterile plants. The mean wet weight of the terasporic, female and sterile plants was 4. 11, 3.42 and 3.25g, respectively. The mean thallus length in female plants was 12.87 cm which was higher than both of variation in two reproductive stages, tetrasporic plants (12.24 cm) and female plants (11.81 cm). Mean agar yield in one year periode was higher in female plants (35.00%) than sterile plants (32.33%) and tetrasporic plants (31.67%). High agar yield were found to coincide with high temperapure.},
