Abstract

Planika (Arbutus unedo L.) je voćna vrsta koja se može pronaći na području Sredozemlja. Ima različite uloge u komercijalnom smislu, te je stoga posljednjih godina postala značajna biljna vrsta za proučavanje. Kako bi se u potpunosti iskoristila njena uporabna vrijednost, potrebno je provesti različita istraživanja njenog potencijala za što uspješniji uzgoj. Cilj ovog rada je bilo utvrditi varijabilnost morfometrijskih svojstava lista i ploda različitih jedinki planika s područja sjeverne, srednje i južne Dalmacije. Fizikalnom i morfometrijskom analizom biljnog materijala dobiveni rezultati ukazuju na razlike istraživanih svojstava između jedinki. Najmanja varijabilnost između jedinki utvrđena je za indeks oblika ploda (IOP), a najveća varijabilnost za masu ploda. Analizom plodova WinSEEDLETM sustavom utvrđeno je da su najmanje varijabilni omjer širine i duljine ploda (W2) i koeficijent oblika ploda (PFC), a najviše zakrivljenost ploda (CS) i volumen ploda s kružnim presjekom (SV). Analizom listova WinFOLIATM sustavom, najmanji varijacijski koeficijent utvrđen je za duljinu plojke mjerene od osnove plojke do mjesta najveće širine plojke/duljina plojke (PMPW/BL), koeficijent oblika (FC), vertikalna duljina (VL) i opseg lista (LP),a najveći varijacijski koeficijent utvrđen za površinu lista (LA). U odnosu na sjevernu, srednju i južnu Dalmaciju, jedinke sa područja sjeverne Dalmacije pokazuju nešto viši stupanj varijabilnosti za većinu mjerenih značajki. Takvi dobiveni skupni podaci bi mogli imati značajnu ulogu u otkrivanju novih genotipova koji bi doprinijeli uvođenju planike kao značajne komercijalne vrste na području Dalmacije.

Abstract (english)

Strawberry tree (Arbutus unedo L.) is fruit species that can be found in the Mediterranean area, it has different role in commercial sense, therefore in recent years has become an important plant species for studying. To exploit its fully value use, it is necessary to carry out various studies in order to explore its fully potential and deliver more successful breeding. The aim of this study was to determine the variability of morphometric properties from leaf and fruit by different individuals of strawberry tree from the territories of northern, central and southern Dalmatia. Based on the analysis of physical and morphometric properties of plant material, results indicate differences of the studying properties between individuals. The minimum variability between individuals is determined for the fruit shape indeks (FSI), and the largest variability for fruit weight. Analysis of the fruit with WinSEEDLETM system found that least variable are ratio of the width and length of the fruit (W2) and fruit shape coefficient (PFC) but the more variable are curvature of the fruit (CS) and volume of fruit with a circular cross section (SV). Analysis of the leafs with WinFOLIATM system, the lowest coefficient of variation is determined by the length of the leaf blade measured from the base of the leaf blade to the place as wide leaf blade / length of leaf blade (PMPW / BL), coefficient of shape (FC), the vertical length (VL) and scale leaf (LP), and the highest coefficient of variation determined for leaf area (LA). In comparison the northern, central and southern Dalmatia, individuals from the region of northern Dalmatia show slightly higher level of variability for most of the measured functions.Such summarized data could have significant role in the discovery of new genotypes that could contribute to the implantation of strawberry tree as significant commercial species on the territory of Dalmatia.
