Research Abstract |
I have successfully developed a method to recognize seasonal time makers in annual tree rings and clarify seasonal growth pattern of trees by comparison between precise variations in cellulose oxygen isotope ratios and meteorological data such as relative humidity. Tentative applications of this method to analyze seasonal tree growth pattern against climate change have told me that much more data are necessary to make some conclusion because of large variability of growth pattern between tree individuals.
