Relationship of Dipterocarpaceae in Ketambe Research Station, Gunung Leuser National Park based on morphological diversity of vegetative organs

Abstract

This study examines the relationship of Dipterocarpaceae in Ketambe Research Station Gunung Leuser National Park. This is based on the study of morphological diversity of vegetative organs which was carried out in July 2015 to June 2016 (one year). Quadrat sampling technique and purposive sampling technique methods were employed in this research and the data was analyzed using R2.10.0 program. Morphology identification and preservation of samples were done at Acehnese Herbarium, Department of Biology, Faculty of Mathematics and Natural Sciences, Syiah Kuala University. The results showed that there were five Dipterocarpaceae species in Ketambe Research Station which are Hopea dryobalanoides, Shorea parvifolia, Shorea lepidota, Shorea johorensis, and Parashorea lucida. These five species were grouped into three clusters, the first clusters consisted of Hopea dryobalanoides, the second cluster consisted of Parashorea lucida, and the third cluster consisted of Shorea johorensis, Shorea parvifolia, and Shorea lepidota. The closest relationship was Shorea parvifolia and Shorea lepidota with a distance of 3.464102. The furthest relationship was Hopea dryobalanoides and Parashorea lucida with a distance of 6.633250.
