We are trying to improve germination success for rare species/varieties of Rosa and Prunus. Any good scarification/germination protocol information appreciated.
sand paper is very useful in Fabaceae - I used it to germinate Oxytropis and Astragalus seeds. Also used a needle aand scarified the seeds one by one by one, but they were big enough

Seeds of roses to keep first in the fridge at least for a month. Inside the frui.
For the germination of the difficult Prunus and Rosacea seeds are useful H2SO4 solution, however with very careful care:
1. Only 20 %-30 % of acid solution should be used
2. Exposition not more than 20 -30 minutes, for some species (Cornus mas) even 40 minutes
3. After removing of seeds from acid rinse with 10 % sodium bicarbonates solution
4. Washing in water
5. Drying out
6. Keeping in moist condition 3- 5 C before of seeding..
