Reference information:
Short-day plants

Short-day plants flower when the night is longer than a critical length. They cannot flower under the long days of summer. In general, these plants flower in late summer or fall, as days are getting shorter. Short-day plants will not flower if a pulse of artificial light is shone on the plant for several minutes during the middle of the night; they require a consolidated period of darkness before floral development can begin. Natural nighttime light, such as moonlight or lightning, is not of sufficient brightness or duration to interrupt flowering.

Some short-day obligate plants are:

Chrysanthemum
Coffee
Poinsettia
Strawberry
Tobacco, var. Maryland Mammouth
Common duckweed, (Lemna minor)
Cocklebur (Xanthium)
Maize - tropical cultivars only

Some short-day facultative plants are:

Hemp (Cannabis)
Cotton (Gossypium)
Rice
Sugar cane
