Specification of Modified Jarvis Model Parameterization for Pinus cembra

The high ambient ozone concentrations cause impairing effects on vegetation leading to plant injuries. potential uptake through open stomata can be quantified using stomatal conductance measurements under the local environmental conditions. This study compares obtained with a modified Jarvis formula adopted from Vegetation Manual of United Nations Economic Commission for Europe, and experimental field measurements’ data. was measured by portable photosynthesis gas exchange analyzer system LiCOR6400. were performed in submontane environment High Tatra Mountains Slovakia Swiss pine (Pinus cembra), as native species flora. According previous studies, is considered an ozone-sensitive species. model compared measurements. suitable parameterization obtained. would help understand its specificity similarity other conifer In case boreal coniferous International Cooperative Programme Effects Air Pollution Natural Crops, validation without temperature adjustment chamber achieved coefficient determination R2=0.75. result not contradiction researches. With optimal set parameters, this paper, reaches R2=0.85. data suggest that Jarvis-type models appropriate are applicable estimation Pinus cembra when do modify regime.
