In order to establish Zostera bed more constantly by using seeds, we examined the relationship between the development status of hypocotyl hair and the adherence strength of Z. marina seedlings. The mean adherence strength of seedlings with well-developed and underdeveloped hypocotyl hair was 3.2 g and 2.0 g, respectively. A large amount of sand adhered to the well-developed hypocotyl hair, and the adherence strength of the seedlings correlated with the amount of sediment. Getting sediment particles and increasing adherence strength with their hypocotyl hair prevent the seeds from flowing out. Moreover, the presence of hypocotyl hair appeared to stabilize the development of leaves and primary roots in the seedlings.
