Abstract

Planika (Arbutus unedo L.) je samonikla mediteranska voćna vrsta koja prirodno raste u obalnom dijelu Hrvatske. Pripada u zapostavljene i neiskorištene voćne vrste u svijetu te je malo istraživanja koja se baziraju na morfološka svojstva planike. Cilj istraživanja je bio utvrditi morfološke karakteristike ploda (duljina, širina i masa) i površina listova te iz dobivenih podataka utvrditi koje samonikle populacije planike pokazuju najveći potencijal za daljnju selekciju. Odabrano je pet lokacija, Preko, Ugljan, Ždrelac, Sukošan i Petrčane. Na svakoj od navedenih lokacija odabrano je po četiri jedinke iz kojih je uzorkovano četrdeset plodova i listova za analizu. Provedena je jednosmjerna analiza varijance (ANOVA), Tukey test kako bi se utvrdila razlika u mjerenim morfološkim svojstvima s obzirom na lokacije i jedinke. Zaključeno je kako su plodovi na lokacijama Preko i Ugljan pokazuju najveći potencijal zbog najveće utvrđene srednje mase ploda. Na Preku je također utvrđena i najveća srednja vrijednost površine listova. Najveća utvrđena duljina plodova je na lokaciji Ugljan, a najmanja kod Sukošana. Najveće utvrđene širine plodova se nisu statistički razlikovale na lokacijama Ugljan, Preko i Ždrelac dok su ponovno najmanje vrijednosti kao i za duljinu utvrđene za područje Sukošana i Petrčana. Prema dobivenim rezultatima lokacija Ugljan i Preko imaju najveći potencijal, ali budući da su jedinke uzete iz prirode potrebno je provesti daljnja istraživanja u ujednačenim uvjetima kako bi se utvrdio stvarni potencijal i potaknuo interes za kultivirani uzgoj planike.

Abstract (english)

Strawberry tree (Arbutus unedo L.) is a wild Mediterranean fruit species that grows naturally in the coastal part of Croatia. It belongs to the neglected and unused fruit species in the world, and there is little research based on the morphological properties of the strawberry tree. The aim of the research was to determine the morphological characteristics of the fruit (length, width and mass) and the surface of the leaves, and from the obtained data to determine which wild strawberry tree populations shows the greatest potential for further selection. Five locations were selected, Preko, Ugljan, Ždrelac, Sukošan and Petrčane. At each of the mentioned locations, four specimen were selected, from which forty fruits and leaves were sampled for analysis. A one-way analysis of variance (ANOVA), Tukey test was performed to determine the difference in the measured morphological properties with respect to locations and specimen. It was concluded that the fruits at the Preko and Ugljan locations show the greatest potential due to the highest determined mean fruit weight. The highest mean value of the leaf area was also determined on Preko. The largest determined fruit length is at the location Ugljan, and the smallest at Sukošan. The largest determined fruit widths did not differ statistically in the locations of Ugljan, Preko and Ždrelac, while the lowest values, as well as the length, were determined for the area of Sukošan and Petrčani. According to the obtained results, the Ugljan and Preko locations have the greatest potential, but since the specimen were taken from nature, it is necessary to carry out further research in uniform conditions in order to determine the real potential and prompt interest in cultivated strawberry tree farming.
