Abstract (croatian)

Božićna zvijezda (Euphorbia pulcherrima Willd. ex Klotzsch.) jedna je od najprodavanijih cvatućih lončanica čija je potražnja najveća krajem studenog i tijekom prosinca za kad se i planira većina proizvodnje. Za uspješnu proizvodnju božićne zvijezde bitno je imati na raspolaganju svjetao i zračan zaštićeni prostor, dobro podešeno centralno grijanje i automatizirano prozračivanje te opremu za regulaciju duljine dana. Zahtjevi božićne zvijezde prema temperaturi, svjetlosti, hranivima, supstratu i ostalim čimbenicima vrlo su visoki tako da je potrebna stroga kontrola proizvodnje. Cilj ovog rada je prikazati taksonomsku pripadnost i porijeklo vrste, način uzgoja te mjere njege i održavanja u primjeni. Rod Euphorbia pripada porodici Euphorbiaceae, a potječe iz Meksika. Najčešće se uzgaja vegetativno iz reznica, premda može i generativno iz sjemena. U uzgoju i primjeni traži svijetlo mjesto, blago kiseo supstrat, redovitu prihranu i umjereno zalijevanje. Najčešće se koristi kao cvatuća lončanica za dekoraciju interijera u vrijeme božićnih blagdana, premda se može koristiti i kao cvjetna vrsta za rez.

Abstract (english)

The poinsettia (Euphorbia pulcherrima Willd. Ex Klotzsch.) is one of the best-selling flowering potplants whose demand is highest in late November and December, when most production is planned. For the successful production of a Poinsettia, it is essential to have a bright and airy sheltered area, well-tuned central heating and automated ventilation, and day-length regulation equipment. The requirements of the poinsettia for temperature, light, nutrients, substrate and other factors are very high, so strict control of production is required. The aim of this paper is to show the taxonomic affiliation and origin of the species, the mode of cultivation and the measures of care and maintenance in use. The genus Euphorbia belongs to the family Euphorbiaceae, and is from Mexico. It is most commonly grown vegetatively from cuttings, though it can also be grown generically from seeds. In cultivation and use, it requires a bright spot, a slightly acidic substrate, regular feeding and moderate watering. It is most commonly used as a flower potplant for interior decoration during the Christmas holidays, although it can also be used as a cut flower.
