Patterns of Copper Bioaccumulation and Translocation in Grapevine Grafts Depending on Rootstocks
Stanko Vršič, Mojca Gumzej, MARIO LEŠNIK, Andrej Perko, Borut Pulko, 2023, izvirni znanstveni članek

Opis: The long-term use of copper (Cu) fungicides in viticulture in Europe has led to Cu accumulation in vineyard top soils. However, less is known about the accumulation of Cu in grapevine grafts after the callusing process/before planting in the nursery. This paper presents the capacity of 5BB and SO4 rootstocks to accumulate Cu, as well as the patterns of translocation in the grafts. After heat forcing (callusing), the grapevine grafts of Sauvignon Blanc on 5BB and SO4 rootstocks were grown in pots for six months in a glasshouse and exposed to various Cu formulations (Cu-oxychloride, Cu-gluconate) and concentrations in peat (50, 150, 500, and 1000 mg Cu of dry weight (DW)). In addition to monitoring the shoot growth dynamics and analyzing the copper content in graft organs, bioaccumulation (BAFs) and translocation factors (TFs) of Cu were calculated. The mean Cu concentrations were ranked as follows: roots (15–164) > rootstock trunks (8–38) > canes (5–21) mg kg−1 DW. The Cu concentrations depended on the Cu formulation and concentration in the substrate. Higher Cu content was found in the roots of both rootstocks (5BB and SO4, 23–155 and 15–164 mg kg−1 DW, respectively) and the lowest in the canes (less than 10 mg kg−1 DW) of grafts grown in Cu-oxychloride-treated peat. Based on the BAFs and TFs, both rootstocks could be considered as Cu exclusive. A higher translocation rate was determined in systemic Cu-gluconate and SO4 rootstock. With shoot length measurements, the significant inhibitory effects of Cu on grapevine grafts growth could not be confirmed, despite the inhibitory effects that were clearly expressed in the first two months of growth. Soils containing more than 500 mg Cu/kg−1 are less suitable for growing vine grafts.

Biometrijska procjena značaja nekih ampelotehničkih zahvata na cv. Zweigelt (Vitis vinifera L.) u vinogorju Feričanci
Vladimir Jukić, Mato Drenjančević, Dražen Horvat, Stanko Vršič, Mirjana Brmež, 2013, izvirni znanstveni članek

Opis: U trogodišnjem pokusu ispitivani su pojedinačni i združeni učinci ampelotehničkih tretmana na količinu šećera i ukupnu kiselost u moštu kultivara Zweigelt. Istraživanja su provedena na proizvodnim površinama FeraVina d.o.o. Feričanci tijekom razdoblja 2006.-2008. godine. Pokus je postavljen po planu podijeljenih parcela (split-plot) u četiri ponavljanja. Za glavni čimbenik određeno je svojstvo «opterećenje trsa» u tri razine (24, 18 i 12 pupova po trsu), a kao podčimbenik «djelomična kasna ručna defolijacija» u dvije razine (ostavljeni i uklonjeni listovi u zoni grožđa). Količina šećera u moštu nije zavisila niti o jednome ispitivanome ampelotehničkome zahvatu, već isključivo o godini, kao najvećem i statistički visoko značajnome izvoru varijabiliteta. Učinci godine i djelomične kasne defolijacije statistički su visoko značajno (P≤0,01) utjecali na smanjenje ukupne kiselosti mošta u odnosu na tretman s ostavljenim lišćem u zoni grožđa.
