Low temperature induces different cold sensitivity in two poplar clones (Populusxcanadensis Monch 'I-214' and P. deltoides Marsh. 'Dvina')
Changes of stem diameter were continuously monitored during winter in two field-grown poplar clones, using automatic point dendrometers. The objective of this study was to find an analytical solution to seasonal synchronization of stem diameter oscillations and low air temperatures. The study identi...

Changes of stem diameter were continuously monitored during winter in two field-grown poplar clones, using automatic point dendrometers.

The patterns of reversible stem shrinkage were related to the cycles of low air temperature. Hourly and daily evidence showed that ‘I-214’ was more sensitive to low air temperatures than ‘Dvina’.
