Our result, indicated that mangosteen buds
(Garcinia mangostana L.) require a long time to
form roots. This parallels the finding of Pertamawati
(2005) who reported new roots measuring only 4.7
mm long, maximum, from mangosteen shoots after
12 weeks of culturing. Another researcher suggests
that the typically slow growth of mangosteen tissue
might be caused by very low number of meristematic
cells, or by the lack of an internal cofactor that acts as
a precursor in the auxin biosynthesis. Auxin increases
the rate of growth (Wulandari & Poerwanto 2010;
Overvoorde et al. 2010).
