Fotoperiodismi on uuritud taimedel juba peaaegu 100 aasta, kuid endiselt on veel palju teadmata. Enamasti pole uuritavateks taimedeks ilutaimed. Töö eesmärgiks on selgitada fotoperiodismi mõjutavaid erinevaid faktoreid ja selgitada, milliste võtetega saab mõjutada päeva pikkust ja selle kaudu ka rohtsete ilutaimede (suve- ja püsililled) arengut. Töö koostamisel on kasutatud raamatuid ja teadusartikleid, millest on välja võetud fotoperioodi mõjutavad erinevad faktorid ning võtted millega saab mõjutada päeva pikkust ja selle kaudu rohtsete ilutaimede arengut. Töö tulemuseks on, millised võtted sobivad kõige paremini rohtsete ilutaimede päevapikkuse mõjutamiseks lühipäeva-, pikapäeva ja päevaneutraalsete taimede puhul tootmises. Erinevad kunstlikud võtted on lisa valgustus, varjutuskangas, temperatuur, kunstlikud ained ja pookimine. Teades kuidas fotoperiodism mõjutab taimede arengut saavad ilutaimede kasvatajad kasutada erinevaid kunstlikke võtteid nende saagi andmise kiirendamiseks, suurendamiseks ja ühtlasemaks muutmiseks.
Photoperiodism in plants have been studied almost 100 years, but still much remains unknown. In most cases test plants are not ornamentals. The work is to identify the various factors affecting photoperiodism and figure out what techniques can affect the length of the day and through that herbaceous ornamentals (summer and perennials) development. The study uses books and research articles that have been taken out how photoperiod is affected by various factors, and techniques that can affect the length of the day and through the development of herbaceous ornamental plants. Result of this work is, what techniques are best suited for herbaceous ornamentals influence of short days, long days and day neutral plants in production. Different artificial techniques are additional lightning, shading fabric, temperature, artificial substances and grafting. Knowing how to influence photoperiodism in plant development ornamental plants growers can use a variety of artificial methods of harvest to get more uniform, complete and rapid flowering.
