Regenerasi Heritiera percoriaceae Kosterm. di Kebun Raya Bogor

Heritiera percoriaceae Kosterm has an endangered category in IUCN red list. This species is known only from Ujung Kulon and Sukawayana, a remnant forest near Pelabuhan Ratu. The Ujung Kulon population occurs in a national park but continues to be threatened by illegal logging, fuelwood collection, infrastructure development, and agricultural encroachment. On the other hand, no seedling found under the tree of H. percoriacea, although bearing fruit. Information about the regeneration of this species is still limited. This research has conducted to predict cause of regeneration of Heritiera percoriacea in the natural habitat. Flowering, fruiting, seedling under the tree in the garden, seed germination in the nursery, and microscopic flower morphology were observed in Bogor Botanic Garden. The result showed that regeneration of H. percoriaceae was blocked by many flowers fall cause of rain and wind, fruit fall by plant diseases, and no seed germination without the treatment.
