Sažetak
Sauvignon Blanc is a widespread and popular grapevine variety for the production of high quality white wines in the Plešivica vine-growing region (Croatia). Soils of the Plešivica vine-growing region are of heavy mechanical composition, low air capacity, and high CaO concentration (30 %) ; all this favours formation of HCO32- ions, which cause disturbances in the uptake of biogenic elements and different types of chlorosis. The research objective was to determine the contents of biogenic macro and microelements in Sauvignon Blanc vine leaf in dependence on the health status (healthy or chlorotic) and age of vineyards (young or old plantation). Investigations included two production vineyards (planted on SO4 stock) on calcareous soil, with average CaO concentration of 30 %, of different plantation age (4 and 15 years). During the 2006 growing period, leaf material was sampled 4 times (twice before, and twice after flowering). Concentrations of the following elements were measured: macro (N, P, K, Ca, Mg) and micro (Fe, Mn, Zn). During the growing period, total nitrogen values ranged from 1.42-3.96 % N, phosphorus 0.20-0.42 % P, potassium 1.08-1.46 % K, calcium 1.42-4.65 % Ca, magnesium 0.14-0.63 % Mg, iron 60.17-161.90 mg Fe kg-1, manganese 44.02-122.30 mg Mn kg-1, zinc 16.66-20.54 mg Zn kg-1. Vineyard age had a significant influence on the concentrations of all microelements and manganese while there were no differences in zinc and iron contents. Sampling dates affected the biogenic elements concentrations whereas no statistically significant difference in their contents was determined between healthy and chlorotic vine-stocks.
