The stable-carbon-isotope ratio (ä13C) of plants is strongly related to the ratio of CO2 assimilation rate and stomatal conductance, and water use efficiency (WUE), and thus ä13C analysis of tree rings gives long-term records on carbon gain and water use associated with wood formation. To identify the effective rainfall seasons for early and late wood formation of Chinese pine (Pinus tabulaeformis Carr.) and black locust (Robinia pseudoacacia L.) in the Loess Plateau, China, an examination was conducted regarding correlations of seasonal precipitation with annual values of ä13C and tree-ring width for early and late wood. The period with the highest correlation was adopted as the most effective rainfall season for interannual variations in tree-ring ä13C and width. This new book discusses and presents results which illustrate the different water use strategies between pine and locust trees. (Imprint: Nova)
