Autonyctotropic
Definition
Relating to autonyctotropism; describing the autonomous bending or folding movement of plant organs (especially leaves or petals) that occurs periodically with the onset of night, determined exclusively by endogenous biological rhythms and internal structural factors, without depending directly on the presence or intensity of an external light stimulus. This mechanism ensures thermal and hydric protection of the foliar apparatus during nocturnal periods.
