摘要:

海草床面积的急剧减少已引起人们对海草床生态修复的重视, 种子在海草床修复中具有较大的应用潜力。该文系统归纳了近年来有关海草种子的研究概况及其应用进展: 从种子生物学和生态学角度对海草种子的形态结构、发育、散布、休眠和萌发进行了归纳比较; 提出了在研究天然海草种子库的同时, 有必要建立人工海草种子库的观点, 并指出建立和完善人工海草种子库需基于种子生物学和生态学研究, 以指导种子的采集和保存; 对海草种子的播种方式和利用种子修复海草床的途径进行了阐述, 并指出了目前研究和应用中存在的一系列问题。最后对海草种子的研究和应用前景进行了展望, 提出海草种子生态学将成为今后的研究热点, 在应用方面, 仍然需要以提高种子萌发率和成苗率为研究重点, 并指出如果利用由种子获得的人工幼苗进行海草床修复, 需首先解决幼苗成活率低的难题。

Abstract:

Reported seagrass bed losses have led to increased awareness of the need for seagrass bed restoration, and seeds have potential for this restoration. In this paper, we systematically review the research and application of seagrass seeds in recent years. The morphology, development, dispersal, dormancy and germination of seagrass seeds are summarized and compared from the viewpoint of seed biology and seed ecology. We propose that when natural seagrass seed banks are researched, it is also necessary to establish artificial seagrass seed banks based on research of seed biology and seed ecology, which will guide seed collection and preservation. Seeding method and the approach of restoration using seeds are discussed, and we also point out problems existing in current research and application. In conclusion, we project expectations of the future in the research and application of seagrass seeds, and we forecast that seagrass seed ecology research will be an emphasis in the future. In the application area, research should focus on increasing the seed germination rate and seedling rate, and the problem of low seedling survival rate must be solved if artificial seedlings grown from seeds are to be utilized to restore seagrass beds.
