Exotic species of fir (Abies Spec. Div.) at the age of 30 years in the nature forest region no. 10 - Středočeská Pahorkatina (Central Bohemian upland).
Results are presented of a provenance plot no. 58 evaluation with various species of genus Abies. Provenance plot no. 58 was established in 1975 in locality Jíloviště (forest ownership Zbraslav, Bartoň from Dobenin). A great deal of genus Abies species and its provenances were represented in this provenance plot. Portion of growing individuals was investigated regularly and height growth measurement with evaluation of phenology was realized at the age of 9 years. Evaluation of phenology used to be very important from that point of view, that level of phenology presents a conditioning factor of species and provenances resistance against late frosts. In case of provenance plot no. 58, individual species of genus Abies and their partial populations were compared with each other and results of evaluation were confronted with results of evaluation of silver fir provenances planted here. Within the framework of presented partial final report, results of the second evaluation from provenance plot no. 58 at the age of 30 years are summarized. Results of evaluation prove perspectives of future use of domestic species-silver fir, namely in the more or less extreme ecological conditions for this species. Considerable variability of partial populations within the framework of this species was also proved as well as convenience of provenances from both Hercynian-Sudeten and Carpathian regions for the Central European conditions.
