Comparison of dendroclimatic relationships using multiple tree-ring indicators (tree-ring width and δ ¹³C) from Masson pine.

ABSTRACT: This study addressed the effects of climate drivers on the tree-ring width (TRW) parameters (total ring width (TR), earlywood width (EW) and latewood width (LW)) and the total ring δ ¹³C series of different wood components (whole wood, α-cellulose and holocelluose) from Masson pine in subtropical China. Pairwise correlation coefficients between three ring width parameters were statistically significant. EW and LW did not reveal much stronger climate sensitivity rather than TR. This indicated that the use of intra-annual ring width has little benefit in extracting more climate information. The mean δ ¹³C series of the three components of the total ring had the strongest climate response to the July-September relative humidity (r = -0.792 (whole woo
