Abstract

The idea of this study is to analyze the effects of climatic drivers on the radial growth (total ring width, earlywood width, and latewood width) and the δ13C series of different wood components (whole wood, α-cellulose, and holocelluose) from Masson pine in subtropical China. Pairwise correlation is significant between three ring width parameters. Earlywood and latewood width did not reveal much stronger climatic sensitivity rather than total ring width. This indicates that the use of intra-annual ring width maybe have little benefit in extracting more climate information. The mean δ13C series of the three components of the total ring had the strongest climatic response to the July–September relative humidity (r= -0.792 (whole wood, WW), -0.758 (holocellulose, HC) and -0.769 (α-cellulose, AC)). These results suggest that whole wood from Masson pine is sufficient to enhance the climate signal without cellulose isolation.

Through both stationary temporal and spatial-statistical perspectives, the moisture drivers (summer/autumn) had a significant impact on three ring width parameters and three components of Masson pine. Overall, the tree ring width parameters and the δ13C series from the total ring showed a different response to the same climate drivers during the same period. The δ13C series may be a more representative climate proxy than tree-ring width parameters for the dendroclimatology in subtropical China.
