Here are some excerps I collected on Palm seed
germination. I hope they help some.
Depending on the species, seed
viability varies from several weeks to six to twelve months. Small seeds
typically have shorter duration of viability. Understory and more tropical seeds
likewise have a shorter time from ripening to loss of viability. As anticipated, seeds
that are from more arid habitats typically have longer viability windows.
Check the seed
’s general appearance. Good seeds
look fresher and feel heavier in the hand. Old seeds
look desiccated and feel lighter.
size. If you know what a seed
is should look like and seeds
received are much smaller, either you have bad seeds
or another species.
Pinch Test: Viable seeds
never collapse when pinched between your thumb and forefinger. If the seeds
do collapse, they are either immature seeds
or they are old, desiccated seeds
with internal air cavities from rot to the embryo or endocarp. Discard such seeds
Float Test: Viable seeds
invariably sink to the bottom when soaked in water and bad seeds
float for the reasons described above. This is providing that any outer fibrous covering layer of the seed
has been removed. There are a few exceptions, but “floaters” usually do not germinate.
Remove fruit from seed
Soak for no more than 24 hours.
A simply constructed germination box made out of styrofoam with a plastic lid can be constructed cheaply and work well. It is ideal for the hobbyist. A simple warming device such as a light bulb can be utilized.
If not utilizing a greenhouse
or germination box, provide your seeds
with the warmest area possible with good humidity and away from direct, hot sunlight.
Humidity levels of 60 to 70% are ideal. Avoid overly damp locations or rot will develop.
Utilize bottom heat to speed germination.
