• Label: Dormancy type
• Entity URI: https://w3id.org/APD/traits/trait_0030415
• Type: categorical
• Definition: Physical [PATO:0002079], physiological [NCIT:C16990], and morphological [PATO:0000051] mechanisms [NCIT:C25343] that inhibit mature [PATO:0001701] seeds [PO:0009010] from germinating [GO:0009845].;Mechanisms that inhibit mature seeds from germinating and the environmental or experimental cues that allow a seed to break dormancy and germinate.
• Additional comments: None
• Allowed values:

  value	description
  morphological_dormancy	Seeds exhibit morphological dormancy, generally because an underdeveloped embryo needs to grow.
  morphophysiological_dormancy	Seeds exhibit morphophysiological dormancy, with both morphological and physiological dormancy mechanisms that must be overcome.
  non_dormant	Seeds are non-dormant.
  physical_dormancy	Seeds exhibit physical dormancy, due to one or more water-impermeable layers in the seed coat.
  physiological_dormancy	Seeds exhibit physiological dormancy, whereby chemical changes are required within the seed to break dormancy, including temperature stratification and after-ripening.
