Abstract
The project deals with the investigation of photooxidants'' impact on chosen terrestrial species. Major part of the project is integrated into an international research project named ICP-Crops (International Cooperative Programme on Effects of Air Pollution and Other Stresses on Crops and Non -wood Plants), carried out under UN/ECE Convention on Long-range Transboundary Air Pollution. Test plants, methods of growing and assessments of injuries are the same as recomended by ICP-Crops protocol.. The main part of investigation represents the experiment with white clover (Trifolium repens L.), as an ozone bioindicator. Plants were exposed at 8 sites in Slovenia, where the experiment with white clover and EDU was carried out. At two sites from eight, the experiment with to ozone resistant (NC-R) and to ozone sensitive (NC-S) white clover clones was perfomed. At both clover experiments leaves'' injuries were estimated and biomass measured according to protocol and compared to measured ozone concentration in air, other pollutants, weather parameters and other site characteristics. Sites were chosen to represent well air pollution and natural circumstances of Slovenia and in areas relevant for agricultural production. Obtained results confirmed occurence of relatively high ozone concentrations in Slovenia and their harmful impact on chosen indicator species. Ozone induced injuries in white clover were greater in rural environment due to steady supply of ozone precursors in urban sites. The level of injuries was different in 1996, 1997 and 1998, mainly due to different climate and changed circumstances for ozone formation, but partly also due to different state of exposed test plants. From the results obtained we could conclude that increasing ozone ond other photooxidants concentrations represent important stress factor for agricultural production and also for natural vegetation. Appart from the experiment described above the fenology of wheat was monitored in 1997 and 1998 in order to determine the sensibility window for ozone in major crops, and occurence of ozone injuries in natural vegetation were evidented in the surroundings of experimental sites.
