/ˈskoʊtoʊˌfeɪz/,

/ˈskoʊtəˌfeɪz/

Origin: Formed within English, by compounding. Etymons: scoto- comb. form², phase n.²

Etymology: < scoto- comb. form² + phase n.²

1. Botany. A stage in the development of a cereal crop (esp. wheat) where short day length is necessary. Now rare.

1939 Herbage Rev. 7 186 In earlier studies..the requirement of these plants [sc. wheat and other cereals] for darkness (the ‘dark’ phase or scoto-phase if the nomenclature is kept uniform) was not accounted for.

1941 Bot. Gaz. 102 734 Following the scoto-phase, vernalized plants of winter wheat require light and a high temperature.

2. Chiefly Biology. A period of darkness, esp. one that is artificially imposed; an artificial night.

1962 Biol. Bull. 122 3 The period of light within the photoperiod is referred to as the photophase; conversely, the dark portion of the photoperiod is termed the scotophase.

1971 Nature 6 Aug. 401/2 Bovines restrained inside environmentally controlled stalls (24 ± 3° C; 70 ± 7% relative humidity; 12 h photophase: 12 h scotophase per 24 h photocycle).

2007 Florida Entomologist 90 715 Mating activity may be constrained during scotophase in part by cooler temperatures and lack of light.
