TLDR
The results support the view that the development of hardiness in woody plants is associated with the augmentation of total cellular protoplasm.Abstract:
Studies of physiological and biochemical changes associated with the seasonal cycle of frost hardiness in the living bark and needles of red pine (Pinus resinosa Ait.) indicate that seasonal changes in soluble protein (borate buffer) and in the rate of incorporation of radioactive leucine into protein are closely correlated with the changes in hardiness. The seasonal cycles of carbohydrates and amino acids do not appear to be closely related to hardiness in red pine. The results support the view that the development of hardiness in woody plants is associated with the augmentation of total cellular protoplasm.read more

Altitudinal increase of mobile carbon pools in Pinus cembra suggests sink limitation of growth at the Swiss treeline
TL;DR: In this article, the authors analyzed mobile carbon pools in Pinus cembra across the treeline ecotone in the Swiss Alps and concluded that carbon limitation is not responsible for reduced tree growth at the alpine treeline.

Involvement of Abscisic Acid in Potato Cold Acclimation
TL;DR: Exogenously applied ABA induced frost hardiness in leaves of Sc plants whether plants were grown under a 20 degrees C or 2 degrees C temperature regime, and the role of ABA in triggering protein synthesis needed to induce frosthardiness is discussed.

Phospholipid, protein, and nucleic acid increases in protoplasm and membrane structures associated with development of extreme freezing resistance in black locust tree cells
TL;DR: It is suggested that normal hardening is a composite of three principal processes which include membrane replication, membrane replication in association with whole protoplasmic angmentation, and starch to sugar conversion.

TL;DR: The present investigation grew out of a similar attempt to assess the relationship of variations in the carbohydrate constituents of the living bark of the black locust tree (Robina pseudo-acacia L.) to the variations in frost hardiness.
