REPRODUCTION PHENOLOGY OF Hydriastele beguinii (Burret) W.J. Baker & Loo. AT BOGOR BOTANIC GARDENS

Abstrak

Hydriastele beguinii (Burret) W.J. Baker & Loo is an endemic palm from Moluccas Island. Reproduction is an important part of plant life cycles to maintain and sustain their existence. The reproduction ability of H. beguinii is relatively low in its natural habitat, therefore studies on its reproduction aspect are required. The main objective of this study is to assess the reproduction phenology H. beguinii at Bogor Botanic Gardens. Three individuals of H. beguinii at initiation phase were selected. This study observed the duration of each phase, morphology changes in every phase and the biotic and abiotic factors affecting the reproduction phenology. The result showed that flower initiation of H. beguinii initiation took 12–16 days, bud towards anthesis took 8–10 days, anthesis took 14-16 days and young fruits to maturity took 110–124 days. The result also stated that in every reproduction phenology phase has a different time period. In addition, reproduction phenology phases were not directly affected by abiotic factors. Trigona laevicep was an insect visitor that was suspected as the pollinator of H. beguinii.
