Abstract

U novije vrijeme sve su manje zastupljene tradicionalne vrste i sorte voćaka, zbog povećane urbanizacije i sadnje novijih, tržištu interesantnijih sorata. Tradicionalne sorte voćaka uglavnom se mogu pronaći na okućnicama u ruralnim područjima gdje se još uvijek uzgajaju i prepoznaje se njihov potencijal rodnosti i kvalitete ploda. Ciljevi ovog rada bili su: utvrditi zastupljenost voćnih vrsta na području Gacke doline, izdvojiti najzastupljenije sorte i utvrditi pomološka te fizikalno-kemijska svojstva njihovih plodova a temeljem dobivenih rezultata odabrati potencijalne sorte za uzgoj i preradu. Provedenom inventarizacijom istraživanog područja utvrđena je prisutnost nekoliko voćnih vrsta (jabuka, kruška, šljiva, trešnja, dunja) koje su tradicionalno prisutne na okućnicama ili ekstenzivnim voćnjacima. Najzastupljenija vrsta je jabuka te su za ovo istraživanje ubrani uzorci plodova osam najzastupljenijih različitih sorata jabuke ('Barunka', 'Ilinjača krupna', 'Kamenika', 'Kanada', 'Ljepocvjetka', 'Podolka', 'Šumska', 'Vlastelica') na kojima su utvrđena pomološka i fizikalno-kemijska svojstva, a rezultati ukazuju kako se tradicionalne sorte značajno razlikuju u istraživanim svojstvima. Sorta 'Kanada' ima zadovoljavajuću veličinu i tvrdoću ploda, indeks razgradnje škroba, što ju čini pogodnu za konzumaciju u svježem stanju, a pogodna je i za preradu zbog povoljnog omjera topljive suhe tvari i ukupnih kiselina te se može preporučiti za daljnje razmnožavanje i uzgoj. Sorte 'Barunka' i 'Podolka' se također ističu u nekim pozitivnim svojstvima te se može iskoristiti njihov potencijal za uzgoj na istraživanom području. Od presudne je važnosti očuvanje i revitalizacija tradicionalnih sorti voćaka, kako zbog njihove tolerantnosti i prilagodljivosti abiotskim i biotskim čimbenicima tako i zbog očuvanja vrijednog genetskog materijala i uporabe njihovih plodova u različite svrhe.

Abstract (english)

In recent times, traditional types and varieties of fruit trees have become less represented, due to increased urbanization and planting of newer, more interesting varieties on the market. Traditional fruit varieties can mainly be found in backyards in rural areas where they are still grown and their yield potential and fruit quality are recognized. The objectives of this study were: to determine the presence of fruit species in the Gacka Valley, to identify the most common varieties and to determine pomological and physico-chemical properties of their fruits and based on the results to select potential varieties for cultivation and processing. The inventory of the investigated area determined the presence of several fruit species (apple, pear, plum, cherry, quince) that are traditionally present in backyards or extensive orchards. The most common type is apple, and for this research, fruit samples were collected from eight most common different apple varieties ('Barunka', 'Ilinjača krupna', 'Kamenika', 'Kanada', 'Ljepocvjetka', 'Podolka', 'Šumska', 'Vlastelica') and the pomological and physicochemical properties of their fruits were determined. It was found that traditional varieties differ significantly in the investigated properties. The 'Canada' variety has a satisfactory fruit size and hardness, starch degradation index, which makes it suitable for fresh consumption, and is also suitable for processing due to the favorable ratio of soluble dry matter and total acids and can be recommended for further propagation and cultivation. Varieties 'Barunka' and 'Podolka' also stand out in some positive traits and their potential for cultivation in the researched area can be used. It is crucial to preserve and revitalize traditional fruit varieties, both because of their tolerance and adaptability to abiotic and biotic factors and because of the preservation of valuable genetic material and the use of their fruits for various purposes.
