Dear colleagues,
I am interested in getting information about papaya seed dormancy (Papaya carica) and methods recommended to overcome it.

If the sarcotesta is removed, then the rate of germination of papaya seeds is greatly speeded up. Furthermore, IF the mesotesta can be removed without injury to the underlying tissues, then this further accelerates germination.

Roberto:
A few years ago we published a paper on germination improvement in papaya seeds. The article discusses the dormancy problem to some extent and you might find this useful.

According to Mr. Muniry Shellimoh from the National Tree Seed Programme in Tanzania, papaya seeds are not dormant and will germinate within 7 days. (The pulp should be cleaned from the seeds).
