The following minimum stratification periods were found: Prunus mahaleb 10-12 weeks, Prunus avium 15-16 weeks, Prunus avium varieties 16-18 weeks, Prunus persica 14-16 weeks. Prunus myro-balana 14-16 weeks, and Prunus damascena more than 20 weeks. The stony shells delay the initiation of germination by 4-5 weeks in myrobalans and peaches, and their removal extends the effective temperature range for after-ripening.
