issue cumari pollux

[Doctor Scoville]

Hey,

does anyone have trouble germinating cumari pollox?

i've got mine in soil, unther a dome, at 29 degrees Celsius for 30 day's at this point.

today tuned it down tot 25 degrees.

cheers. Stijn

Germination efficiency is not a property of the variety but critically depends on the seed storage conditions. Pepper seeds lose viability really fast when stored without protection from heat and humidity. Optimal conditions would be heat sealed with drying agent and oxygen absorber in the freezer. But just keeping them in a fridge would help a lot.

thnx. i doubt storage is the issue. all others variaties from the same batch sprouted 100% and within a week or so. So i wonder because this is a kind of different variety, 29 degrees might be to hot. Has anyone grown this one?

A general trick that I apply to uncooperative seeds (seeds in general, not just peppers) is to change the growing conditions from optimal to unfavourable for a while. I let the soil dry out completely. In your case, I'd switch of temperature control as well. After some time, reestablish optimal germination conditions again.

I think this is great advice overall but the first sentence is patently untrue. It is for certain a property of a few species of Capsicum including C.rabenii,the species Cumari Pollux belongs to. There is empirical evidence all over the internet…a lot here as a matter of fact.

I think your information on storage is as sound as possible and even more important for these wild species since there are not as many outlets to source them and most are untrustworthy.

I believe from little experience that this temperature can be an issue at times with wild species. I personally have had far more success with lower temperatures. Try 22-24C for a bit or fluctuate between that and your typical temperature. As mentioned before in this thread,those fluctuations in temp and moisture have triggered success for many of us with these more difficult to germinate species.

Good luck. When you succeed you will be happy with the beauty of this one.

Sounds like a plan. Many thanks.
tuned off the heat for now, so they will be at 20 degrees. this week i will try move them to 24 en 29 degrees and back. We'll see what happens.
Would a fridge night of about 5 degrees be a terrible idea?

 

[Doctor Scoville]

still no result. temperature change did not yet doe the trick. starting to think bad luck.

 

[Doctor Scoville]

resown. this time I'm trying the deno method.

You are only as good as the quality and viability of your seeds.

Also, what time frame are we talking here. If you are giving up on C.rabenii in 30 or 40 days,odds are you are throwing away perfectly good seeds. If I had one answer for having success germinating wild Capsicum seeds it would be patience. 90 days is not uncommon in this realm.
