Roystonea Royal palm seed viability

[dwimss]

Hello, 

I got some fresh seeds from a royal palm (Roystonea Regia), and I'm wondering how long it takes to lose viability it's winter here I do have a green house but it gets cold during the nights (10-15 C / 50-60F).
I think it's best to wait t'ill May and plant them during the hot period but I'm afraid that at this time they will lose their viability, In my experience most of palm tree seeds tend to lose viability quickly after harvesting.

PS : During the day the temperature in my green house is around 30-35C / 85-95F sunny days only.

What do you think, is it  better to wait 6-7 months and plant them ?

I'd plant them right away.  I just got a batch of approximately 100 roystonea regia seeds on October 13th at our CFPACS meetup.  By October 27th, I already had 14 germinate.  They are out in the garage putting down their first root right now.

I can't say with certainty that they will lose viability quickly, but that is often a characteristic of palms from humid/tropical areas.

In 2 weeks wow this is fast!!

My concern is that I'm not living in Florida and it gets cool here during the nights right now, so if I plant them now they might not germinate and probably rot before it gets warmer!

You can put them on top of a water heater or in another area that stays warm.  In my case, I can just put them near a south-facing window.  In the winter, sometimes that isn't enough and I'll use a heat mat to germinate seeds.  You have some options if you are worried about cool/cold.

Rather than wait 6-7 months why not place them in a community pot and place it someplace extra warm. After seedlings germinate place the pot where they can get lots of light and warmth. By spring you can plant them or move them to individual pots.
