Multiple Step-wise Regression Approach used to assess the relationship between traits of genotypes measured at the beginning of the experiment (acclimation period) and change in shoot production due to elevated temperature.

We estimated new shoot production two ways: (a) difference in number of new shoots between elevated and the mean of control genotypes at the end of the recovery period and (b) difference in number of new shoots produced under elevated temperature at the end of the warming period vs. the end of the recovery period.
