The objective of this study was to determine the effects of an electromagnetic field from a high voltage transmission line on the yield of agricultural crops cultivated underneath and near the transmission line. For 5 years, experiments with winter w

Tropospheric ozone has been recognised as a limiting factor for plant growth since late fifties of our century. The decrease in the rate of light saturated net photosynthesis (Asat) was shown to be the major effect of ozone in leaves with negative co

Tropospheric ozone and high light intensities are two stress factors that often occur simultaneously under natural conditions. Ozone is well known to form oxygen radicals in the apoplastic water and long lasting photoinhibition can cause photooxidati

Light-saturated net leaf photosynthesis (A sat ), CO 2 response curves (A/C i ), current photochemical capacity (F v /F m ) and pigment contents were measured in leaves of Populus nigra (Clone T107) which had been exposed to ozone stress in open-top

Mature zygotic embryos of Abies alba mull were placed on a modified MCM medium (basal medium-BM) with 2.2 μM benzyladenine and 2.3 μM kinetin to induce embryogenic suspensor masses (ESM). These ESM proliferated on induction medium supplemented with

It was tested whether field-grown plants (Phaseolus vulgaris, Zea mays and Helianthus annuus) reflect photoinhibitory effects under natural conditions. Attached leaves were used for determination of the photochemical capacity of Photosystem II (Fv/Fm

Forest ecosystems are particularly affected by the impact of stress factors. Apart from natural stressors, there are also anthropogenic ones such as air pollutants. Ozone is considered to be the most phytotoxic air pollutant in Austria on a regional

Ozone is the most important air pollutant in Europe for forest ecosystems and the increase in the last decades is significant. The ozone impact on forests can be calculated and mapped based on the provisional European Critical Level (AOT40 = accumula

Electron paramagnetic resonance (EPR) spectra of Pinus sylvestris and Larix decidua seeds show that priming with PEG + 200 mg kg –1 gibberelic acid (GA 3 ) results in appreciably higher free radical contents than in unprimed control samples. Only r
