Excerpt from Growth Studies in Forest Trees: I. Pinus Rigida Mill; II. Pinus Strobus L Little stress was put on the study of secondary root thickening in the present investigation. Only one cutting was taken, on April 27, 1910, for purposes of comparison, so that no reliable deductions can be made. At this time cambial activity was not manifest, although it must have been in process throughout the aerial portion with the possible exception of the apical shoot. T. Hartig (8) claimed that cambial awakening in the roots is much later than in the aerial portions. He gave midsummer as the time of first inception and said it continued far into October.

The latter is manifest often as early as March and continues throughout the season. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
