Table I. Correlation between endoreduplication and other leaf growth variables.
Pearson’s correlations between EF and six leaf growth variables (epidermal cell area in leaf 6 [CA], epidermal cell number in leaf 6 [CN], leaf 6 area [AL6], rosette leaf number [LN], relative rosette expansion rate [RER], and rosette leaf area [RA]) in the 88 mutants, the wild-type Col-0, the 109 lines from the Ler × An-1 RIL population, and the two corresponding parental lines are shown. Significance values are as follows: *** P < 0.001. When correlations were significant in both sets of genotypes, the differences of slopes and intercepts between the two sets were tested by an analysis of covariance. *** P < 0.001.
