Additional file 1 of Comparison of chrysanthemum flowers grown under hydroponic and soil-based systems: yield and transcriptome analysis

Additional file 1: Figure S1. Pearson correlation coefficients among 3 biological replications from chrysanthemum flowers under the soil system (Flower-CK-1, Flower-CK-2 and Flower-CK-3) and hydroponic system (Flower-SP-1, Flower-SP-2 and Flower-SP-3). The numbers in the scale bar stand for correlation coefficients. Figure S2. Principal component analysis among 3 biological replications from flowers under soil and hydroponic system. Figure S3. Difference of total nitrogen content in chrysanthemum flower under soil and hydroponic system. *P < 0.05, **P < 0.01.
