Struktur Benih dan Dormansi pada Benih Panggal Buaya (Zanthoxylum rhetsa(Roxb.) D.C.
Abstract: Panggal buaya
(Zanthoxilum rhetsa (Roxb.)
D.C.) is generally
used as raw
material of wooden craft industry, because it has smooth texture
with interesting color and it is also easy to process using both hand and
machine. In order to anticipate the raw material insufficiency, panggal Buaya
planting is very important. However, the resistance faced in the panggal Buaya
stand development was the difficulty of it’s germination. The information on
its cultivation and seed management are still very limited. The other problems
onits development was plant
propagation which was
caused by the
existence of seed
coat dormancy. This research was aimed to
know the cause of
seed coat dormancy
on panggal buaya seed through
lignin contents at seed
coat and seed
coat structure microscopically, and
then, to know
effective dormancy faulting
treatment and finally, to learn the effect of this treatment to the microscopic
structure of panggal buaya seed coat. The research shows that submerging the
panggal buaya seed in sulfate acid 95% as long as 30 minutes that follow the
submerging it in water which has room temperature for along 1 x 24 hours could
stop the dormancy of the seed (grow potential 40,7%, germination capacity 39,7%
and growing rapidity 0,698% KN etmal-1). Presumably, the faulting mechanism of
dormancy is caused by the damage of cell wall of coat seed through lignin
dissolving process by sulfate acid (delignification).
