Fig. 3.

Correlations of ring index values with growth temperatures of strains SCM1 (15–35 °C), HCA1 (10–30 °C), and HCE1 (10–25 °C). The linear regression lines of SCM1 (solid line), HCA1 (dashed line), and HCE1 (solid line) are $y=0.076x+1.40\hspace{0.17em}\left(r^2=0.96\right)$, $y=0.082x+0.77\hspace{0.17em}\left(r^2=0.94\right)$, and $y=0.058x+1.31\hspace{0.17em}\left(r^2=0.95\right)$, respectively. Error bars represent the SD of data from triplicate cultures (some error bars are too small to be visible in the figure).
