meadows have suffered a great decline in the world. In recent years, transplantation of seagrasses has been considered to be an effective method to mitigate and control seagrass degradation. To assess the adaptation of seagrass transplants to new environment, w of eelgrass plants, which were transplanted two years ago. Resulted showed that chlorophyll contents were lower in spring and early summer, but relatively higher during other period. Eelgrass roots were most abundant in winter and early spring. The length of sheath and leaves, width of leaves and the dry weight per individual shoots reached the maximum levels in summer, while the lowest values were observed in fall. The highest and the lowest values of leaf productivity per shoot occurred in summer and fall, respectively. The emergence rate of lateral shoots was the highest in winter, while no lateral shoot emergence was observed in fall. Results indicated that chlorophyll contents were affected by light, whereas the morphology, growth and clonal growth of eelgrass water temperature. In addition, the inducedwas greater than thatby lower water temperature in winter.
