We quantified ascorbate, glutathione and α-tocopherol in fine roots of mature Fagus
sylvatica L. under free-air canopy ozone (O3) exposure (twice ambient O3 concentration …

The influence of long-term free-air ozone fumigation and canopy position on leaf contents of
total glutathione, its redox state, non-structural proteins (NSP), soluble amino compounds …

In this study the influence of chronic free-air ozone exposure and of different meteorological
conditions in the very dry year 2003 and the more humid year 2004 on the antioxidative …

The activities of superoxide dismutase, ascorbate peroxidase, monodehydroascorbate
radical reductase, and dehydroascorbate reductase and the contents of ascorbate …

The effect of free-air ozone fumigation and crown position on antioxidants were determined
in old-growth spruce (Picea abies) trees in the seasonal course of two consecutive years …

The goal of the present study was to examine the effects of slow and rapid changes of ozone
(O3) concentrations on the physiological behaviour of current‐year needles of Norway …

Two‐year‐old red spruce (Picea rubens Sarg.) seedlings were exposed to various levels of
ozone, from 0.4 to 3 times ambient levels, in open‐top chambers in Ithaca, NY, USA …

Three-year-old beech (Fagus sylvatica) seedlings growing in containers were placed into
the sun and shade crown of a mature beech stand exposed to ambient (1× O 3) and double …

We compared ascorbate contents of current-year Picea abies needles with respect to tree
age and crown position. To exclude microclimatic influences, potted seedlings were …

To investigate the effects of ozone exposure and soil drought, singly and in combination, on
gas exchange, antioxidant contents and pigments in current-year needles of Norway spruce …
