摘要：As contribution to solution of silver fir problems, there were 20 provenance research plots established in former Czechoslovakia, between 1973 and 1977. Presented paper includes results of evaluation of 19 provenances on research plot no. 57 - Lesy Jíloviště, Cukrák (Central Bohemia), at the age of 35 years. Nine evaluated provenances originate from the Czech Republic, two from Slovakia, two from Bosnia and Herzegovina and at one from Germany, Austria, France, Romania and from Italy. Total height and DBH have been measured, average stem volume and average stem growing stock per 1 ha have been counted according to yield tables, stem form and health state have been assessed visually. Differences among provenances´growth have been statistically processed and interpretation of obtained results has been formulated. Variability on the base of nature forest regions, climatypes and European forest zoning has been assessed.
