short-day plant

short-day plant A plant in which flowering is favoured by short days and correspondingly long nights. There are two groups of such plants, some species in which there is an absolute requirement for these conditions for the onset of flowering, and other species in which flowering is merely hastened by them. In fact, however, the term is somewhat misleading in that the critical factor is the period of darkness and short-day plants require a night of more than a minimum duration. Horticulturists exploit this, for example, by exposing chrysanthemums to a brief flash of light during the night to delay flowering until Christmas.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
