Abstract

The aim of the work was to analyze intra- and interspecific variations in radial growth dynamics of vegetative progeny from three Eurasian 5-needle pine species (Pinus sibirica Du Tour, P. koraiensis Siebold&Zucc., P. cembra L.). The object of the study was the 21-year-old vegetative progeny from six Siberian stone pine ecotypes, three Korean pine ecotypes, and one Swiss stone pine ecotype created by grafting the scions from parental trees on the local Siberian stone pine rootstock, which were grown under similar conditions in the south of the Tomsk Oblast, Russia. The variation among the species was quite substantial: radial increment of the Swiss stone pine was almost twice as great as that of the Siberian stone pine, and radial growth of the Korean pine was intermediate. The Siberian stone pine had the highest level of intraspecific variation, and the Korean pine had a lower level. In general, the annual ring width of both species decreased from the southern ecotype to the northern ecotype. Strong incompatibility was observed between scion and rootstock when the Korean pine was grafted on the Siberian stone pine; the other combinations were quite compatible. The interannual variations in the radial increment were determined by the local environmental and climatic conditions rather than by the origin of the parent trees. All three species showed a significant positive correlation between the residual growth indices and the April temperature and the July precipitation
