Abstract

Tulipani su, uz ruže i krizanteme, najpopularnije cvjetne vrste za rez koje poglede privlače raznim kombinacijama boje, veličine i oblika cvjetova. Riječ Tulipa dolazi od perzijske riječi „dulbend“, što znači turban, a označava oblik cvijeta. Vrsta je dobila ime po švicarskom botaničaru Conradu Gessneru koji je prvi opisao vrstu. Najznačajnija vrsta je Tulipa gesneriana koja je u današnje vrijeme predak preko 4000 kultivara tulipana. U povijesti je postojalo razdoblje, tzv. tulipomanija, u kojem su tulipani dosegnuli veliku popularnost. Glavni razlog njihovog uzgoja je za rezano cvijeće, ali se sade na otvorenom u vrtovima i javnim nasadima. Razmnožavaju se vegetativno, lukovicama, a u uzgoju se razlikuju niski, srednji i visoki kultivari s jednostavnim ili dvostrukim cvatovima.
Cilj rada je istražiti utjecaj triju temperatura sušenja na kvalitativna svojstva ocvijeća tulipana. Za istraživanje su odabrani kultivari Tulipa 'Catherina' bijele boje, Tulipa 'Red princess' crvene boje i Tulipa 'Strong gold' žute boje. Latice odabranih kultivara su se sušile u dehidratoru i vakuum sušari. Iz dobivenih rezultata odredila se brzina otpuštanja vode iz latica, udio proteina u istim te intenzitet boje.

Abstract (english)

Alongside with roses and chrysanthemums, tulips are the most popular cut flowers, captivating us with their colorful combinations, various flower shapes and sizes. The word “Tulip” comes from the Persian word “dulbend”, which translates to “turban”, plainly indicating the shape of the flower. The flower was named after a Swiss botanist, Conrad Gessner, who was the first to describe the tulip flower. The most important species is Tulipa gesneriana, which today, is the ancestor of over 4,000 cultivars of tulips. During the “tulipomania”, a period in history, the tulips gained great popularity. The tulips are planted outdoors, in gardens and public plantings, but the main reason for their cultivation is for cut flowers. Tulips are propagated vegetative, via bulbs. In cultivation, we distinguish low, medium and tall cultivars with simple or double flowers.
The aim of this paper is to investigate the influence of three drying temperatures on the qualitative properties of tulip flowers. The cultivars which were selected for the research include Tulipa 'Catherina' white, Tulipa 'Red princess' red and Tulipa 'Strong gold' yellow. The petals of the selected cultivars were dried in a dehydrator and a vacuum dryer. The rate of water release from the petals, the proportion of protein in them and the color intensity were determined from the obtained results.
