• Label: Leaf heat tolerance minimum critical temperature (Tcrit-hot or Tcrit-max)
• Entity URI: https://w3id.org/APD/traits/trait_0020421
• Type: numeric
• Definition: A temperature response trait [TO:0000432] which is the temperature [PATO:0000146] threshold at which photosystem II [GO:0009539] begins to become inactive [PATO:0002355] as the leaf temperature increases (is heated) [PATO:0001305]. This is a modelled parameter [STATO:0000034] derived from the inflection point on a temperature - basal chlorophyll A fluorescence [GO:0090546] curve.;The temperature threshold at which photosystem II begins to become inactive as the leaf temperature increases. This is a modelled parameter derived from the inflection point on a temperature - basal chlorophyll A fluorescence curve.
• Additional comments: None
