Abstract

Od 2014. godine bilježi se nagli porast u proizvodnji stolnih sorata grožđa. Hibridizacijom su stvorene nove sorte stolnog grožđa otporne na gljivične bolesti te na niske zimske temperature, u posljednje vrijeme poželjna agronomska i gospodarska svojstva. Cilj ovog istraživanja bio je opisati glavna agronomska i gospodarska svojstva stolnih sorata `Monarh bijeli`, `Blagovijest`, `Arkadia` i `Viking` posađenih na VVP Jazbina u periodu od 2016. do 2018. godine. Navedene su sorte posađene na podlozi Kober 5BB. Sorte `Monarh bijeli` i `Blagovijest` uspostavljene su na sustavu uzgoja Zadarska lepeza s kosim krovom, dok su `Viking` i `Arkadia` uspostavljene na jednostrukom Casenave kordoncu. Klimatske prilike 2022. godine karakterizirale su iznadprosječne temperature i ispodprosječna količina padalina. Sorte `Monarh bijeli`, `Arkadia` i `Blagovijest` tek su ove godine ušle u prvi rod, dok sorta `Viking`, iako je posađena prije 4 godine, još uvijek nije ušla u prvi rod, zbog čega je isključena iz opsežnijih istraživanja. Istraživanje je pokazalo da je sorta `Monarh bijeli` imala najveću masu bobica, kao i masu grozda, dok je `Arkadia` prikupila najviše šećera, a `Blagovijest` zadržala najveću koncentraciju ukupne kiselosti. Na temelju rezultata organoleptičke analize grožđa, može se zaključiti kako se ocjenjivačima okusom sviđaju sve navedene sorte, pri čemu muškarci preferiraju sortu `Monarh bijeli`, a žene `Arkadiu`. S obzirom na dobivene rezultate istraživanja, valja naglasiti važnost primjene agrotehničkih i ampelotehničkih zahvata (navodnjavanje, defolijacija, cizeliranje itd.) kako bi prinos bio što kvalitetniji. Budući da u Hrvatskoj nema istraživanja o navedenim stolnim sortama, velika je potreba za daljnjim istraživanjima istih s ciljem povećanja znanja proizvođača stolnih sorata, kao i krajnjih potrošača.

Abstract (english)

Since 2014, there has been a significant increase in the production of table grape varieties Through hybridization, new table grape varieties resistant to fungal diseases and low winter temperatures were create. Through hybridization, new varieties of table grapes resistant to fungal diseases and to low winter temperatures, recently desirable agronomic and economic properties, were created. The aim of this research was to describe the main agronomic and economic properties of table grape varieties `Monarch`, `Blagovijest`, `Arkadia` and `Viking planted` on VVP Jazbina in the period from 2016 to 2018. The listed varieties were planted on the Kober 5BB substrate. Varieties `Monarch` and `Blagovijest` were established on the Zadar fan growing system with a sloping roof, while `Viking` and `Arkadia` were established on the single Casenave cordon. Climatic conditions in 2022 were characterized by above-average air temperatures and below-average precipitation. The `Monarch`, `Arkadia` and `Blagovijest` varieties had the first crop this year, while the `Viking` variety, although it was planted 4 years ago, still did not had the first crop, which is why it was excluded from more extensive research. The research showed that the `Monarch` variety had the highest berry weight, as well as the bunch weight while `Arkadia` collected the most sugar and `Blagovijest` retained the highest amount of acidity. Based on the results of the organoleptic analysis of the grapes, it can be concluded that the testers like the taste of all the listed varieties, with men preferring the `Monarch` variety and women `Arkadia`. Considering the obtained research results, it is necessary to emphasize the importance of applying agrotechnical and ampelotechnical operations (irrigation, defoliation, chiseling, etc.) in order to make the yield as high as possible. Since there is no research on the mentioned table grape varieties in Croatia, there is a great need for further research on them with the aim of increasing the knowledge of producers of table grape varieties, as well as final consumers.
