I soaked somme recalcitrant seeds for 24 jours in 500 ppm solution( i used efervescent gibberellic acid pills to make the solution).African persimmon D Lycioides,a verry rare annonaceae ,Uvaria Grandiflora seeds.These seeds i had them in wet paper towels for 4 months allready without any sign they would germinate.And i also sprayed 200 ppm acid solution on 2 small feijoa seedlings.Il announce later if the seeds will germinate or if the feijoa seedlings will grow to become monsters.

After a week nothing happened ,so i made fresh solution with 1500 ppm and Uvaria Grandiflora and Diospyros Lycioides seeds are soaking again for 24 hours.Its also possible that the seeds might be too old and dead so even gibberellic acid that was used to germinate thousands of years old seeds ,might not revive them.

Update about gibberellic acid.The only feijoa seedling that wasnt sprayed with acid solution ,died.The otther 2 that were treated survived and they do well.Today i scarified somme verry old pecans brought from supermarket.They were soo old and dry that the kernel inside had cracked ,but i mannage to get a few good ones ,like less than a quarter and they are soaking now for 24 hours in 500 ppm gibberellic acid solution.After that they will go in the fridge for a month or 2 ( its called cold stratification ).Last time i germinated supermarket brought pecans,i got 2 percent germination rate without gibberellic acid and 3 months in the fridge.

I use Gibberellic acid. Each plant to germinate has different needs. High doses are very dangerous, it will make all your plants weak and spiny.

Pithecellobium dulce with red flesh( guamucil/ manilla tamarind) with 500 ppm Gibberellic acid/24 hours bath resulted in 100 percent germination.
Uvaria Grandiflora doesnt give any sign.I might have verry old seeds but i will order soon another batch of seeds.

200ppm is not much, but be careful it will make your plants leggy and week once they start growing
I wonder how you make the ga3 solution, do you know the protocol?

I use 500 ppm as the lowest dose.What protocol are you talking? To mix the acid with alcohool or acetone first?

Purple mangosteen seeds in 500 ppm gibberellic acid/24 hours.The seeds are directly from fruit but the larger one got a bit dryed for a few days.I also peeled the seeds from the furry outer layer.

Acetone is very toxic to seeds
