Figure 7

The effect of different blue (B) light proportions supplemented by light emitting diodes (LED) on the abscisic acid (ABA) content (A) and β-glucosidase (B) activity of freeze-dried rose leaves grown under high relative air humidity (RH; 90%). For ABA quantification the samples were collected in the middle of the light and dark period. For β-glucosidase quantification, only samples from dark period were used. Data are the mean values ± SE of 5 samples each consisting of 5–6 leaves from each of plants. Different letters within each figure indicate significantly different values (P< 0.05).
