h Granum height; N thylakoid layers per granum; SRD stacking repeat distance; d granum diameter; Area granum area in cross section; GLI granum lateral irregularity; GSI granum cross-sectional irregularity; GITOT total granum irregularity. The number of analyzed chloroplasts and grana is reported for each line. Values are expressed as medians with [Q1] and [Q3]
P values were obtained from Wilcoxon signed-ranks test
