Clustering and KEGG analysis of differential metabolites between N28 and N67 under LT treatment. a Cluster heating maps of N28 and N67. The abscissa represents the sample name, and the ordinate represents the difference metabolites and hierarchical clustering results. ML28 and ML67 refer to N28 and N67 samples germinated at LT, respectively. 1 ,2 and 3 refer to the three replicates. Red means high content, green means low content. b KEGG analysis of N28 and N67. X-axis represents Rich factor. The greater the Rich factor is, the greater the degree of enrichment is. The larger the point is, the greater the number of differential genes enriched in the pathway is. The redder the color of the dot is, the more significant the enrichment is
