Abstract

Contains 24 papers, some already noticed [cf. FA 31 No. 5076; 32 Nos. 2068, 4697], presented at a conference at the University of British Columbia, Feb. 19-20, 1970, in four sessions. (1) Biology of tree ring formation: The development of the annual ring in Grand Fir (J. S. Bethel); Effects of...

Abstract

A comparison of precipitation records with ring widths in Pinus ponderosa showed that precipitation was a significant factor affecting natural growth, but it was not possible to draw reliable conclusions about precipitation patterns from growth patterns.KEYWORDS: Dendrochronology \ Growth relation...

Abstract

The measurement of annual rings is considered, and the relationship between ring width, ring radius and ring index is discussed. A simple method is described for determining the equation for the age trend of rings. The account is illustrated by examples from Swedish pines [Pinus sylvestris],...

Abstract

Density curves examined in conjunction with X-ray photographs of increment cores of Abies alba, Picea abies, Pinus sylvestris and Pseudotsuga menziesii, show that they give a reliable picture of moisture distribution within the annual rings. Minimum and maximum values (particularly the maximum)...

Abstract

Gives equations, derived from increment cores from six 140-year trees of Pinus halepensis, and based on the size, number and rate of increase of cells in an annual ring, geometrically considered, to calculate: the number of cells produced in a year to form a given growth ring; the number of cell...

Abstract

From analysis of the annual rings for 1946-1962 from trees in (1) the Pinetum polytrichosum and (2) the P. herbosum, derives the following expressions: n = 0.25 + 4.86b for (1), and n = 6 + 1.94b for (2), where n is a linear count of vertical resin canals [per cm.] and b is ring width. The number...

Abstract

Comparisons of increment cores taken in 1955-56 from four 80-year-old Pines which had been completely freed in 1950-51, and from 11 controls from closed parts of the same stand, showed significant increases in ring width and particularly in the proportion of early wood in the former, even though...
