| Abstract | The surfgrass Phyllospadix torreyi occurs in rocky intertidal and shallow subtidal zones and local populations are often subject to anthropogenic disturbances that require restoration. The utilization of early life stages for restoration has been hampered by a lack of information about germination and growth of seedlings. Various methods for manipulating germination time and enhancing early root growth were tested in a series of laboratory culture experiments using seeds of P. torreyi collected from field populations. Germination rates were generally high (at least 70% after 4 weeks) with most seeds displaying a dormant period of at least 14 days. Cold, dark culture conditions were found to delay germination for periods up to 83 days, without affecting germination rate. Other experiments revealed that a single application of a low concentration of a commercially-available plant hormone resulted in a two-fold increase in the root mass/total mass ratio, an effect that was not enhanced by repeated application or by higher concentrations. These results have important implications for restoration of P. torreyi, because they indicate that early life stages can be readily stored, germinated and grown in laboratory culture, and they suggest that development of cost-effective restoration methods using early life stages may be feasible.
