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.不同温度下，以培养液氧同位素δ¹⁸O值为自变量、幼苗纤维素氧同位素δ¹⁸O值为因变量的线性回归参数（斜率与截距）。相关系数与统计学显著性分别列于第四行与第五行。第六行的斜率差异项展示了各组斜率的具体差异：若两组斜率未共享同一字母，则二者斜率存在显著统计学差异。
