Abstract:
Sugar wood (Aphanamixis polystachya (Wall) R.N. Parker) is a medicinal plant that is widely used for
herbal medicine. Sugar wood distribution areas are China, India, Sri Lanka, Thailand, Laos, Vietnam,
Malaysia, Indonesia, Philippines, New Guinea, and the Solomon Islands. However, nowadays sugar wood
trees are increasingly difficult to find, so they need to be cultivated by planting. The purpose of this study
was to determine the best type of media for the germination of sugar wood seeds (A. polystachya). The
research was conducted in the nursery of Forest Research and Development Centre Bogor. The method used
in this study is an experimental method using a single factor completely randomized design technique with
three replications. The media factor consisted of soil, sand, soil mixed with rice husk (2:1), and soil mixed
with charcoal (2:1). Parameters observed were: germination, speed of germination, seed moisture content,
and germination value. The results showed that the use of sand media had the highest germination speed and
germination value (14.00% per etmal and 13.80%) while the use of soil media had the lowest germination
speed and germination value (32.33% per etmal and 7.52%). Otherwise germination capacity of seed
ranging from 64.67% (on soil media) - 91.33% (on mixed media of soil and rice husk).
