Capsule dehiscence — opium poppy

Papaver somniferum L.

Capsule dehiscence in opium poppy (Papaver somniferum) is a genetically determined mechanism where the seed capsule opens through specialized pores, resulting in seed loss.

In the reference 5 varieties crop Opium poppy, where this is mentioned in the description.

In opium poppy breeding, dehiscence is considered a morphological trait that determines the capsule's ability to retain seeds after reaching physiological maturity. Unlike other crops where cracking is caused by water stress, in poppy, this process is linked to a natural seed dispersal mechanism, which breeders purposefully suppress for industrial cultivation.

The target trait for varieties is indehiscence, or the "closed capsule" state, which prevents seed shattering and enables mechanized harvesting. Evaluation of this trait is conducted visually by checking for the presence of pores in the upper part of the capsule and is expressed as a qualitative characteristic of the sample or as a percentage of yield loss.
