Variability of needle structure in Siberian stone pine in provenance plantations

TL;DRAbstract

Siberian stone pine (Pinus sibirica Du Tour) is one of the most common trees in Siberia. Its natural range is from the Ural Mountains to the Aldan river and from the Arctic Circle to northern Mongolia. The climate in natural Siberian stone pine sites influences the whole plant organism, particularly its needle structure, and the response to thisoccurs at specific morphological and anatomical levels. The genotypical and environmental effects on needle structure in different Siberianstone pine ecotypes are very little known. One effective way to examine and to separate genotypical effects from environmental ones is byusing a common garden experiment. The purpose is to analyze morphological and anatomical needle variability in Siberian stone pinemarginal populations that have been grown in provenance plantations in southern West Siberia, Russia. The needle samples were collectedin the provenance plantation located 30 km south of Tomsk (the southeastern West Siberian Plain
