Fotoperiyodizm

Fotoperiyodizm, bitkilerin gÃ¼n uzunluÄŸu baÄŸlÄ± olarak geliÅŸim gÃ¶stermesi.

Gece ve gÃ¼ndÃ¼z uzunluÄŸunun yÄ±l iÃ§indeki Ã§evrimi, bitkilerin bÃ¼yÃ¼mesini ve Ã§iÃ§eklenmesini doÄŸrudan etkiler. Ã–rneÄŸin kÄ±sa gÃ¼n bitkisi denen bazÄ± bitkilerde, gecelerin kÄ±salÄ±p gÃ¼ndÃ¼zlerin uzadÄ±ÄŸÄ± mevsimde yalnÄ±z kÃ¶k, dal ve yapraklar geliÅŸtiÄŸi halde, gÃ¼ndÃ¼zler ya da Ä±ÅŸÄ±k alma sÃ¼resi belirli bir minumum altÄ±na dÃ¼ÅŸÃ¼p geceler uzadÄ±ÄŸÄ±nda ilk tomurcuklar belirir ve bitki hÄ±zla Ã§iÃ§eklenir. Oysa uzun gÃ¼n bitkilerinde durum tam tersidir ve bitkinin Ã§iÃ§eklenmesi iÃ§in karanlÄ±k dÃ¶nemin ya da gecelerin kÄ±sa, gÃ¼ndÃ¼zlerin uzun olmasÄ± gerekir. BazÄ± bitkilerde ise, gece-gÃ¼ndÃ¼z uzunluÄŸu eÅŸitlendiÄŸinde Ã§iÃ§eklenme hÄ±zlanÄ±r.
