Fig. 5

Root mean square error (RMSE) value between response surfaces based on the shoot fresh weight of mature plant at harvest and seedling growth parameters: shoot fresh weight (SFW), root dry weight (RDW), leaf area (LA), SPAD, LA×SPAD, SFW/LA and LA/projected leaf area (PLA) (A). All response value data were normalized for comparison. Their position of optimal combination ratio based on each parameter is shown on a triangle that has red (R), green (G) and blue (B) lights as three vertexes (B)
