In my experience, seed of named jujube cultivars may not be viable, even 
with stratification.

A grower in our areas uses seed set on suckers that emerge below the 
graft union. Such seedling rootstock shoots are very thorny and produce 
small fruit, but the seeds are 100% viable.

The grower places the seed in a vice and slowly squeezes the seed until 
the hard covering cracks. As I recall, this seed will germinate 
immediately if provided bottom heat is apply, even without previously 
cold storage.
