a
Statistics for interaction terms can be found in Table S4.
b
Values followed by a letter combination sharing one or more letters are not statistically different at the P value of <0.05 based on Tukey’s post hoc test.
c
Values are treatment averages which were calculated based on all data for one particular treatment level.
