BestKeeper software statistics for reference genes based on Ct values in the somatic embryogenesis and the germination groups.

CP equivalent terminology for Ct, standard deviation (SD; ± CP): the SD of the CP (values greater than 1 are highlighted in red); Coefficient of variance (CV; %CP): the CV expressed as a percentage of the CP level. The correlation between each candidate reference gene and the BestKeeper index was calculated using Pearson’s correlation coefficient (r) (values correlated well are highlighted in green) and the P value³¹.
