Label: Anther dehiscence
Entity URI: https://w3id.org/APD/traits/trait_0012415
Type: categorical
Definition: An androecium morphology trait [TO:0000994] which is the length [PATO:0000122] and shape [PATO:0000052] of the stomia [PO:0020101] that form the anther dehiscence zone [PO:0005011]; stomia are the usually slit-like [PATO:0002482] openings in the anther [PO:0009066] through which pollen [PO:0025281] is released.;Anther dehiscence refers to the type of opening of the anther when releasing its pollen through the stomia.
Additional comments: Definition and trait values derived from Schoenenberger et al. (2020) for their character '313. Anther dehiscence (D1)'

Allowed values:

value	description
circular	Anther with a transverse slit that goes entirely around the anther.
common_stomium_confluent_thecae	The two thecae of a single anther are fused at one end with a single pore through which pollen exits.
flap_valvate	Anther with one or more flap-like valves on horizontal hinges, opening vertically.
h_valvate	Anther with two valves on longitudinal hinges, opening horizontally as salon doors; when the stomium bifurcates at its distal and/or proximal end and thus a valve is formed.
longitudinal_slit	Anther with longitudinal slits that extend along the entire length of each theca.
pores_many	Anther with pollen exiting from many pores along its length.
poricidal	Anther where dehiscence of longitudinal slits is incomplete, with pollen exiting via a small pore at the tip.
short_apical_slits	Anther where dehiscence of longitudinal slits is incomplete and only occurs over a short extent at the apical end of the theca.
short_basal_slits	Anther where dehiscence of longitudinal slits is incomplete and only occurs over a short extent at the base of the theca.
short_central_slits	Anther where dehiscence of longitudinal slits is incomplete and only occurs over a short extent at the center of the theca.
t_valvate	Anther with T-shaped stomium; reduced transverse slit at base.
transverse_slit	Anther with horizontal slit.
