“…The occurrence of frost rings is generally limited to small trees and therefore may be most readily found in the centre of older trees between ground level and a height of 2-3 m in the stem (Glerum 1975). Their less frequent presence higher up in the stem is tacitly acknowledged, but I have found no documented evidence of occurrence there.…”

In codominant and suppressed trees in two red pine (Pinus resinosa Ait.) plantations in Simcoe County, Ontario, frost rings had formed at the start of most annual rings in the two internodes below the current leader until the trees were nearly 14-m tall. None occurred in the current shoot growth or below the sixth internode. They seldom formed when the stem radius (inside bark) exceeded 2 cm.Dans deux plantations de pin rouge (Pinus resinosa Ait.) du comte de Simcoe in Ontario, on a releve sur des tiges codominantes et opprimees des fentes annulaires dues au gel dans le bois initial de la plupart des cernes de croissance situes dans les deux entre-noeuds les plus proches de la fleche teminale des arbres de moins de 14 metres. Rien de semblable n'apparait sur la pousse de I'annee ou au dessous du sixieme entre-noeud. Ces fentes annulaires dues au gel surviennent lorsque le rayon de la tige est superieur a 2 cm (sous 6cosce).
