Fig. 2From: Identification of candidate tolerance genes to low-temperature during maize germination by GWAS and RNA-seq approachesDistributions of and correlations between 14 relative phenotypic traits. The frequency distribution of each trait is shown on a central diagonal in the form of a histogram. Scatter plots of between every pair of traits are shown in the areas below the diagonal, and numerical correlation coefficients between every pair of traits are shown in the areas above in the diagonal. *, ** and *** indicate significance at P < 0.05, P < 0.01 and P < 0.001, respectivelyBack to article page
