All quality parameters, except ascorbic acid and lambertianin C,
varied significantly between the harvest seasons.
The main harvest period was July–August, and most berries were
developed from late June to early August. Both temperature and
precipitation in this period might have effects on chemical composition
of the fruits. The average monthly temperatures did not vary
substantially between the three seasons, but considerable differences
in precipitation were observed Significant effects of environmental factors on phytochemicals in
plants have been reported in previous studies However, in
experiments carried out in natural habitats, because of confounding
effects of interacting environmental factors, it is difficult to
point out effects of individual factors on chemical composition of
fruits stressed that accumulation of selected
phytochemicals in fruits may be affected both by genetic and environmental
factors. In the present work, the lowest concentrations
of selected bioactive compounds were detected in 2010. Genotypes
characterised by stable fruit quality independent of climate conditions
are preferred both for the fresh market and for processing. In
the present study, the variation among standard quality parameters,
expressed as coefficient of variation (CV), between all genotypes,
using average values from the harvest period 2009–2011,
was the lowest for pH (3%) and hue (5%) and the highest for
