description |
The effects of seed moisture and storage temperature on storability of an
orthodox (Instia palembanica), an intermediate (Swietenia macrophylla) and a
recalcitrant (Hopea odorata) forest tree seed were studied. The objectives were to
determine the critical and optimum moisture and storage temperature for storage of
each of the three species, and to evaluate the potential of these seeds for
cryopreservation at ultra-low temperatures of liquid nitrogen. The study was
divided into four parts of three experiments, each being for one of the three species.
In Part I, the effects of desiccation on seed viability were evaluated. The
orthodox seed, I. palembanica, has low shedding moisture of 10%. It was tolerant
to desiccation as its critical and optimum moistures were low at 6% and 8-10%
respectively. For the intermediate seed, S. macrophylla, it was more sensitive to
desiccation. Its shedding moisture was high at 37% and it could not withstand excessive desiccation as its critical and optimum moistures were high at 1 5% and
25% respectively. The recalcitrant seed, H. odorata, has very high shedding
moisture of 48% and was highly sensitive to even slight desiccation. Its critical and
optimum moistures were very high at 29% and 32-35% respectively. |
