Abstract

Istraživane su mogućnosti očuvanja i revitalizacije nasada starih sorata jabuke u sklopu Centra za rehabilitaciju 'Ozalj'. Utvrđivanjem stanja nasada uočeno je da su neke voćke pred izumiranjem, te da voćnjak nije bio redovito održavan. Nakon uzimanja uzoraka plodova, determinacijom je utvrđeno da se radilo o sortama 'Bijeli zimski kalvil', 'Bobovec', 'Božićnica', 'Crveni delišes', 'Jonathan', 'London peping', 'Lijepocvjetka', 'Šampanjka' i 'Zeleni štetinec'. Nakon provedenih osnovnih fizikalnih analiza, te stavljanja plodova na čuvanje u hladnjaču s normalnom atmosferom, utvrđeno je da se sorte značajno razlikuju po istraživanim svojstvima. Po kakvoći su se istaknule sorte 'Bijeli zimski kalvil' i 'London peping', jer su imale najveću masu, visinu i širinu, te najmanji kalo. Nakon vađenja plodova iz hladnjače, najveći udio zdravih plodova utvrđen je kod sorata 'Bobovec' (92%) i 'Jonathan' (90%).
Kako bi se spriječilo dalje propadanje ovog voćnjaka, nužno bi bilo provesti revitalizaciju nasada na način da se na stablima koja su još uvijek u dobroj kondiciji izvrši jača rezidba postupno kroz nekoliko godina, a sa stabala koja odumiru uzmu plemke, te se cijepe na vegetativnu podlogu. Odumiranjem stabala starih sorata, gubi se naše prirodno i kulturno nasljeđe, genetska raznolikost, a te sorte koje su se tijekom godina prilagodile lokalnim agroekološkim uvjetima mogu biti i osnova ekološkog uzgoja voća.

Abstract (english)

We have investigated possibilities of preservation and revitalization of the old orchard with old apple cultivars at the Rehabilitation Centre 'Ozalj'. By determining the state of the plantation, it was noted that some fruit trees are close to extinction and the orchard wasn't regularly maintained. After taking samples of fruits, determination confirmed they were cultivars 'Bijeli zimski kalvil', 'Bobovec', 'Božićnica', 'Crveni delišes', 'Jonathan', 'London peping', 'Lijepocvjetka', 'Šampanjka' and 'Zeleni štetinec'. After the basic physical analysis and putting fruits in cold storage with normal atmosphere, it was determined that analised cultivars signifficantly differ in investigated characteristics. By the means of quality the best cultivars were 'Bijeli zimski kalvil' and 'London peping' because they had the highest weight, height and width, and the lowest weight loss. After removing fruits from cold storage, the highest rate of healthy fruits were found in the cultivars 'Bobovec' (92%) and 'Jonathan' (90%).
In order to prevent further declining of this orchard, it would be necessary to revitalize it in a way that trees which are still in good shape needs to be prune strongly, gradually within a few years and from trees which are dying needs to take the scions, and graft them on a vegetative rootstock. By dying out of trees of old cultivars our natural and cultural heritage and genetic diversity is lost, this cultivars that have over the years adapted to local environmental conditions can also be the basis of organically grown fruits.
