Subject field(s)
  • Plant Biology
CONT

Hypericum foliosum Aiton, is a beautiful Azorean endemic species whose populations currently yield a low number of individuals in many of the archipelago islands. In order to find an effective ex situ multiplication strategy for this plant several studies were carried out. During a 3 years span the germination capacity of its seeds was tested. The essays took place under a continuous temperature of 15°C and 10-20°C alternate, for a period of 8 hours light and total darkness, In alternate temperature tests the light period was made to coincide with the highest temperature. The species showed a positive photosensitivity and germination percentage of 67% under a continuous 15°C temperature.
