摘要:In this study, the variability of physiological parameters of five provenances of European
beech (Fagus sylvatica), which were planted at two locations with different ecological conditions at
Fruška Gora and Debeli Lug, was estimated. Provenance trials were established in the framework of
COST Action E52: "Evaluation of Beech Genetic Resources for Sustainable Forestry". 2-3 years old
seedlings originating from Croatia, Germany, Bosnia, Austria and Serbia were planted in blocks of
fifty plants with a spacing of 2 x 1 m. Physiological parameters such as net photosynthesis, rate of
transpiration and stomatal conductance were measured with a portable gas analysis system. Generally,
provenances from Fruška Gora Mountain showed higher intensity of all physiological parameters than
provenances located at site Debeli Lug. High correlations among rates of net photosynthesis and
transpiration, on one side, and stomatal conductance, on the other side, were found. ANOVA test
indicates that variability of net photosynthesis, transpiration and stomatal conductance of investigated
provenances, at the two locations, was influenced both by environmental conditions of sites and
genetic constitution of provenances
