I'll jump in with my usual stupid question.
The few grower/hybrydizer in Italy claim that diploids can be sowed immediately. while tets requires at least 45 days of refrigeration, but they mean dry refrigeration. This maybe is due to the will of keeping a secret for themselves (you know, kinda the hidden trick they don't want to tell), but what about dips/tets sowing? Is there some study in this?
BTW I have seed from a cross with H.Citrina. Just one sprouted but all produced the small root beginning while in peroxide solution. Since the small seedling seems suffering maybe the seeds were not good?
