I agree these are very connected and i think that having night and day within photoperiodism would be a good idea —Preceding unsigned comment added by 76.160.173.80 (talk) 12:17, 17 April 2008 (UTC)

[edit] Merge

We needn't have three stubs, but only one good article. Aelwyn 07:28, 19 September 2007 (UTC)

I agree. The three articles should be placed under"Photoperiodism". User:Sebanti —Preceding unsigned comment added by 220.226.80.60 (talk) 07:59, 25 September 2007 (UTC)

I also agree, combining the articles on different plants (long/short/neutral period) underneath the main article of "Photoperiod" or "Photoperiodism" (they should direct to one another) would be much more concise. - MF —Preceding unsigned comment added by MrFacchin (talk • contribs) 02:59, 12 November 2007 (UTC)

We mustn't forget that photoperiodocity applies to more than plants. It applies, too, to animals changing the color of their feathers/coats to correspond to the seasons, migration, reproduction etc. Hordaland 15:59, 14 November 2007 (UTC)

In fact, I think we need two articles: Photoperiodism (botany) and Photoperiodism (zoology) (with disambiguation at Photoperiodism, Photoperiodocity etc.). The subject is extremely important wrt animals' seasonality, while readers may well be interested particularly in plants or animals. Both subjects can be seen as sub-topics of Chronobiology. --Hordaland (talk) 14:00, 27 January 2008 (UTC)

this is true. it will be also helpful for the users to search —Preceding unsigned comment added by Hsg2189 (talk • contribs) 06:29, 14 December 2007 (UTC)

It would also be helpful for novices (like myself) to have some examples of the types of plants as this helps to 'fix' the ideas and explanations with real life experiences. User : Jim Ewing. —Preceding unsigned comment added by Jim.ewing (talk • contribs) 21:11, 10 January 2008 (UTC)

• Dr. Singh's comment moved here from above the Merge heading:

I agree that we should merge long day plants, short day plants and day neutral plants with photoperiodism because these subcategories of plants arise from photoperiodism itself.

That may be, but I will repeat my suggestion from January (above) that we need two articles: Photoperiodism (botany) and Photoperiodism (zoology). It's possible that the article Chronobiology should be included in a reworking of the whole subject.

(Dr. Singh, I'm moving your comment to below the rest of the 'Merge' discussion.) --Hordaland (talk) 11:35, 17 April 2008 (UTC)

I edited this page because the discussion of the effects of moonlight on phytochrome was not correct. Also, the measurement of night length is not under the control of phytochrome itself but the 'external coincidence' of light (sensed by phytochrome, or another receptor, in daylight) with the phase of the circadian clock. I would recommend "Photoperiodism in plants" by Thomas and Vince Prue (Academic Press, 1997) for further reading on this subject. —Preceding unsigned comment added by 130.126.91.51 (talk) 00:22, 16 May 2008 (UTC)
