The concentration of macroelements in plant biomass is determined by
nutrient uptake from the soil and depends on the spatially variable
environmental conditions and nutrition status in the soil. The aim of
this study was to examine the macroelement concentrations in pedunculate
oak (Quercus robur L.) leaves and to compare them with soil
heterogeneity. ANOVA, MANOVA and discriminant canonical analysis (CDA)
were used to estimate population variability in the macroelement
concentrations in pedunculate oak leaves and surrounding soil. The
results of ANOVA revealed a statistically significant difference between
populations -in ash content, N, Ca, Mg, P, and all nitrogen scaled
variables (all P < 0.05) in Q. robur leaves. MANOVA revealed a
statistically significantly difference between populations -in soil pH,
P2O5 and K2O concentrations (all P < 0.05). The P in Q. robur leaves had
the highest total canonical standardized coefficients on the first
canonical variable (CDA1) and was responsible for discrimination between
populations. Foliar analysis of pedunculate oak leaves and soil analysis
showed statistically significant spatial variability in macroelement
concentrations between populations in Serbia, which were determined by
the bioavailability of essential minerals in the soil.
