Earlywood and Latewood Features of Pinus sylvestris in Semiarid Natural Zones of South Siberia

Abstract

Chronologies of the anatomical and integral parameters of the Scots pine (Pinus sylvestris L.) earlywood and latewood were investigated for two sites in the Minusinsk depression with different soil moisture conditions. Patterns of statistical characteristics and climatic responses of the chronologies were identified. Differences between sites were revealed in the cell diameter and wall thickness distributions. These differences are indicators of adapting pine wood structure to the moisture deficit.
