%X A precondition necessary for creation and selection of genotypes tolerant of stress conditions is a study of physiological, biochemical and molecular bases of their adaptive reaction to stress. The study includes 40 lines of free pollination originating from 5 provenances: Sutjeska, Vi egrad, Tara, Tesli  and Durmitor (B&H, Serbia and Montenegro). Two populations were selected from each provenance, i.e.: 5 lines of free pollination represent the population growing on the cliffs and 3 lines of free pollination represent the population growing at the best site of Austrian pine. Specific characteristics of the studied provenances, populations, and free pollination lines were confirmed by the analyses in the salt-soluble proteins. The identical protein composition was proved in a small number of cases in the replicates of the same free pollination line, which indicates a high intra-line variability, which can be the result of the effect of father, as well as of heterozygosity of mother trees. The analyses of protein composition of seed showed considerable differences at provenance level. Inter-line, population and provenance differences, and also, the interaction between the origin and drought factor, were recorded for 9-day-old seedlings germinated in induced drought conditions and in normal conditions.
