Kosteletzkya pentacarpos is important for the restoration of coastal habitats in Asia and is vulnerable in Europe. Physical dormancy (PY) prevents ready seed germination and seedling production for restoration and conservation purposes. In this study, seed germination and seedling growth of K. pentacarpos were investigated in response to scarification treatments (manual scarification, percussion) and population origin (i.e., wild, cultivated ex situ and reintroduced). Manual scarification best promoted seed germination (98-100%), but resulted in damages to the cotyledons (on 64% of seedlings, on average) and lower seedling growth. Percussion did not significantly increase seed germination, but best promoted seedling growth. There was a significant reduction of PY in seeds produced by plants cultivated ex situ and/or reintroduced. Our results indicate that scarification treatments and ex situ cultivation may have important implications in translocation and other uses of K. pentacarpos.

Abstract

Kosteletzkya pentacarpos is important for the restoration of coastal habitats in Asia and is vulnerable in Europe. Physical dormancy (PY) prevents ready seed germination and seedling production for restoration and conservation purposes. In this study, seed germination and seedling growth of K. pentacarpos were investigated in response to scarification treatments (manual scarification, percussion) and population origin (i.e., wild, cultivated ex situ and reintroduced). Manual scarification best promoted seed germination (98-100%), but resulted in damages to the cotyledons (on 64% of seedlings, on average) and lower seedling growth. Percussion did not significantly increase seed germination, but best promoted seedling growth. There was a significant reduction of PY in seeds produced by plants cultivated ex situ and/or reintroduced. Our results indicate that scarification treatments and ex situ cultivation may have important implications in translocation and other uses of K. pentacarpos.
