摘　　要：海草床是沿岸海域重要的初级生产者,具有极其重要的生态价值和经济价值,是重要的浅海生态系统之一.本文综述了近年来国内外对海草种子休眠、萌发、幼苗生长及其影响因素的研究进展,总结了海草种子的休眠方式和休眠历期及其影响因素,探讨了盐度、温度、光、激素、溶解氧及种群等因素对海草种子萌发、幼苗存活和生长的影响,并对目前研究中存在的问题和今后的研究方向进行了展望.Seagrass bed is the main primary producer in coastal areas,having highly ecological and economical values,and being one of the most important shallow-marine ecosystems.This paper reviewed the research progress in the seed dormancy,germination,and seedling growth of seagrass and related affecting factors,summarized the seed dormancy modes and durations and their affecting factors,and discussed the effects of water salinity,temperature,transparency,hormone,dissolved oxygen,and population structure on the seed germination and the seedling survival and growth.Some issues in related researches and several research directions in the future were prospected.
