The PCA Biplot shows data variation of the main experiment. The parameter in PCA: C/N ratio of grain (C_N Grain) and shoot (C_N Shoot) biomass, fraction of water transpired before flowering (FTWF), leaf area at flowering (LA_flow), leaf area at DAS 77 (LA_77), shoot biomass (Shoot), thousand-grain weight (TGW), normalized transpiration rate at DAS 42 (Tnorm_42) total nitrogen shoot (TN Shoot), total phosphorus shoot (TP Shoot), total nitrogen grain content (TN Grain), total phosphorus grain (TP Grain), total amount of transpired water (Transpiration). The larger circles show the cluster center of each cluster, while the smaller circles show individual data points.
