Low temperature induces different cold sensitivity in two poplar clones (Populus x canadensis Monch 'I-214' and P. deltoides Marsh. 'Dvina').

abstract：:Plants are sessile organisms forced to adjust to their surrounding environment. In a single plant the photoautotrophic shoot is exposed to pronounced environmental variations recurring in a day-night 24 h (diel) cycle, whereas the heterotrophic root grows in a temporally less fluctuating environment.
