Linear regression parameters between oxygen isotope ratios of seedling cellulose and culture water.

Parameters (slope and intercept) of linear regressions of the δ18O value of seedling cellulose on that of the culture water at various temperatures. Correlation coefficient and the significance are shown on the fourth and fifth row respectively. Difference of slope row (row 6) shows specific differences in the slopes. If they do not share a common letter, then slopes are significantly different.
