RC-value of stem tissue of silver birch as an indicator of cold acclimation

Abstract

The aim of this study was to examine the development of the cold acclimation of silver birch ( Roth) seedlings. The effect of fertilization was also studied. The seedlings were two-year-old. As a comparison stump sprouts from the near-by forest were used. The seedlings were treated in temperatures of +5°C (= control), –5°C and –15°C four times with conductivity measurements and with ocular inspection.Betula pendula
