摘　　要：在采用生长重建法(reconstruction methods)研究海南新村湾泰来藻Thalassia hemprichii的有性繁殖过程中,发现泰来藻花芽形成期和种子萌芽期分别在每年的秋季末(11月初)和次年春季初(2月底),比菲律宾泰来藻种群早约2个月,雌雄花比例为1∶4,单次开花率是0.95%。Reconstruction methods were employed to estimate the flowering and seedling efficiency of seagrass Thalassiahemprichii at the Xincun bay of Hainan Island. The results revealed that Thalassia hemprichii initiated flowers in early November and the seedlings appeared in late February next year, which were nearly two months earlier than the population in Philippine did. The ratio of female to male flowers was 1 ： 4. It was observed that only 0.95% of Thalassia hemprichii shoots produced flowers at this time.
