Fig. 2From: Differences in flavonoid pathway metabolites and transcripts affect yellow petal colouration in the aquatic plant Nelumbo nuciferaChanges of flower color parameters (L*, a*, b* and C*) of MLQS and YGB at five flower colouration stages. The y-axis scales the mean value of three biological repeats. Lower case letters show significant differences (P < 0.05) of the color parameter among stages based on ANOVA and Duncan’s multiple range testBack to article page
