Effect of Indoor Exposure on the Cold Hardiness and Physiology of Containerized Christmas Trees

Gooch, N. J., Nzokou, P., and Cregg, B. M. HortTechnology 19(1):72-77. 2009.

We examined physiological and morphological changes of three species black hills spruce (Piceaglauca), balsam fir (Abies balsamea), and douglas fir ( Pseudotsuga menziesii var. glauca) subjected to in -home conditions for 10 and 20 days. Shoot cuttings were subjected to artificial freeze testing (AFT) and the physiological and morphological changes were evaluated by chlorophyll fluorescence, bud mortality, and needle damage.
