Morfološka i kemijska analiza introduciranih sorti nektarine u Hercegovini

A 2-year study was done to compare fruit morphological and chemical composition of three nectarine cultivars grown in south Hercegovinia conditions. A high variability among and within cultivars was found and significant differences were observed among them in all properties analyzed. On the basis of evaluated data, the best fruit performance was registered in ‘Caldesi 2000’ and ‘Venus’ grown in the condition of this part of the Mediteran. This evaluation may help to select a set of nectarine cultivars with better fruit quality attributes, which in our growing conditions might be indicated in ‘Caldesi 2000’ and somewhat in ‘Venus’. The highest average of fruit width (61.18 mm) and fruit weight (148.24 g) was found in cultivar Caldesi 2000. As for friut thickness, also cultivar Caldesi 2000 had the highest value (55.39 mm). The results for the highest fruit length (60.48 mm) had Venus cultivar also fruit stone weight length, width and thickness. The contents sugars (glucose, fructose) total soluble dry matter, and total acids in fruits were found in cultivar Venus, but pH and sucrose were found in cultivar Sun Grand.Provedeno je dvogodišnje istraživanje kako bi se usporedio morfološki i kemijski sastav plodova tri sorte nektarine uzgojene u južnohercegovačkim uvjetima. Utvrđena je velika varijabilnost između i unutar sorti te su uočene značajne razlike među njima u svim analiziranim svojstvima. Na temelju procijenjenih podataka najbolji učinak ploda zabilježen je kod sorti \u27Caldesi 2000\u27 i \u27Venus\u27 uzgojenih u uvjetima ovog dijela Mediterana. Ova procjena može pomoći u odabiru niza sorti nektarina s boljim svojstvima kvalitete ploda, što bi u našim uvjetima uzgoja moglo biti označeno kao \u27Caldesi 2000\u27 i donekle \u27Venus\u27. Najveći prosjek širine ploda (61,18 mm) i mase ploda (148,24 g) ima sorta Caldesi 2000. Što se tiče debljine ploda, također je sorta Caldesi 2000 imala najveću vrijednost (55,39 mm). Rezultati za najveću duljinu ploda (60,48 mm) imala je sorta Venus kao i težinu, širinu i debljinu koštice ploda. Sadržaj ukupne topljive suhe tvari, šećera (glukoza, fruktoza) i ukupnih kiselina u plodovima utvrđen je kod sorte Venus, a pH i saharoza kod sorte Sun Grand

Fenološka proučavanja sorti breskve na području Dubravske visoravni u Hercegovini

The aim of this study is to examine dynamic and energy of flowering, as well as phenophase of ripening for peach varieties Maycrest, Springcrest, Spring Lady, Rich Lady and Elegant Lady in the area of Dubrave plateau in Herzegovina in 2009-2011 period. The results of research show that statistical differences does not exist in the beginning of flowering between varieties (1-3 days), there is correlation between the beginning of flowering and ripening. Climatic factors had significantly great influence on the the beginning and the duration of the flowering of peaches, and therefore in the areas with increased risk of spring frosts it is recommended to cultivate varieties with later flowering period.Cilj rada je ispitivanje dinamike i energije cvjetanja, te fenofaze zrenja sorti breskve Maycrest, Springcrest, Spring Lady, Rich Lady i Elegant Lady na području Dubravske visoravni u Hercegovini u periodu od 2009-2011. godine. Rezultati istraživanja pokazuju da nisu ispoljene značajne razlike u vremenu početka cvjetanja između sorti (svega 1-3 dana), niti postoji korelacija između vremena cvjetanja i zrenja. Na početak i trajanje cvjetanja breskve znatno veći utjecaj imali su klimatski faktori, te se u područjima povećane opasnosti od proljetnih mrazeva preporučuje gajenje sorti kasnijeg vremena cvjetanja

The Phenology of Flowering and Ripening of Almond Cultivars Nonpareil, Texas, Ferraduel and Genco in Herzegovina

Aims: The area of sub-Mediterranean Herzegovina, including the area of Mostar, is favourable for growing of almonds. However, this advantage has not been sufficiently exploited so far. A wide selection of almond varieties is available, so it is a challenge to select the best variety for successful cultivation in the agroecological conditions of Herzegovina, and to justify the economic investment. Therefore, it is necessary to evaluate their phenological characteristics in order to determine their adaptability to environmental conditions of Herzegovina. This paper describes the dynamics of flowering and fruit ripening of four varieties of almonds in climatic conditions of Herzegovina, in Mostar. The goal of this paper is to establish the dynamics of flowering in the Mostar area of these cultivar almond types: Nonpareil, Texas, Ferradueland Genco. Study Design: For the purposes of research work, there was an experiment set up by the method of random pool arrangement, with three trees of each cultivar. Place and Duration of Study: The experimental part of this work was carried out in a part of private property located near the village of Gnojnice, Municipality of Mostar. The survey was conducted on two occasions, more precisely in two vegetations, during 2013 and 2014. Methodology: The dynamics of flowering were recorded for each cultivar through three phenophases:    •  Beginning of flowering - the date when 10% of tree flowers are opened;   •  Full flowering - the date when 90% of tree flowers are opened;   •  End of flowering - the date when more than 90% of leaf petal fell of the tree. Results: The research results showed a big correlation between flowering phenophases flow and meteorological conditions in some research years. In 2014, the flowerings began 14 to 18 days earlier (depending on variety) in comparison to 2013. The earliest flowering was recorded for the variety “Texas”, and the latest was recorded for varieties of Ferraduel and Genco. Conclusion: Flowering duration was pretty equal for all the varieties (from 17 to 21,3 days), while the shortest duration was recorded for the varieties Genco (17) and Ferraduel (17,3) in 2013. All the varieties had earlier fruit ripening in 2014 in comparison to 2013. Fruits of Texas variety had the latest ripening, while the varieties Nonpareil, Ferraduel and Genco ripened at the same time. All the monitored varieties showed an extreme adaptability to agro-ecological conditions of Herzegovina and may be recommended for commercial cultivation

Evaluation of autochthonous apple varieties (Malus domestica) in the area of Tomislavgrad

The research included seven autochthonous apple varieties in the area of Tomislavgrad, Stipanjići locality, during 2018, which represent the natural wealth of our country. In seven autochthonous apple varieties: Petrovača bijela, Budimka, Ljutika-Divljaka, Ledarica, Bedrica, Ljepocvjetka-Cvjetača and Jonatanka, phenological characteristics were monitored and analyzed with morphological-pomological properties of fruits. The following phenological characteristics were monitored: flowering phenophases, germination of the first fruits, fruit growth, fruit ripening and full maturity. Five characteristics for the description of apple fruits were determined using the UPOV descriptor for apples (UPOV, 2003). The results of monitoring the morphological and pomological properties of fruits show that the lowest average fruit weight was in the variety of Cvjetača (58,38 g), while the highest average of fruit weight had variety Bedrica (140,59 g). In the result is evident that the lowest value of fruit width had variety Cvjetača (53,72 mm), and the highest had variety of Jonatanka (70,83 mm). The Cvjetača variety had the lowest average fruit lenght (47,24 mm), while the Bedrica variety had the highest (59,72 mm). The Budimka variety had the highest average stem length (2,73 cm), while the Divljak variety had the lowest average stem length (1,43 cm). The Jonatanka variety had the largest average cup concavity and was (1,28 mm), while the Petrovača bijela variety (0,41 mm) had the lowest average cup concavity. Based on the this research, the examined autochthonous apple varieties can be used a valuable genetic material in breeding programs, and can be used to create new varieties, as well as for propagation in commercial plantations
