Abstract
Amorphophallus
titanum (Becc.)
Becc. ex Arcang (the
giant corpse flower) is a plant collection icon of Bogor Botanic Gardens. The
inflorescence of A. titanum has always attracted
many people in the
world and plant science. A few botanic gardens or institutions worldwide have
also grown this species. However, their
reproductive biology characters have challenged their cultivation and
domestication efforts. This species rarely produce fruit/seeds because the male
and female flowers are not mature simultaneously. The success of the pollination indicated
by fruit production depends on the
interaction between the insects and the maturity of male and female flowers
from different individuals.
Therefore this study on the cross-hand pollination to
produce seeds is very important
to support the ex-situ conservation
efforts of this collection in Bogor Botanic Gardens. Based on on the observations, the
flowering period of this species was at least every three year. The
bloom of A. titanum number
VI.C.484 (origin: Lahat, South Sumatera)
which opened on 2 February 2012 was pollinated manually using (stored) pollen
taken from the other flower number VI.C.485 (the same origin) which bloomed on
29 November 2011. The
hand cross-pollination was successful and the first fruit (infructescence)
to be produced here on 22 February 2012
marked the first success of manual pollination of the Titan Arum in Indonesia. On
this research,
the morphology of pollen of A.
titanum was observed and their viability was tested.
