B0R100, B10R90, B25R75 B50R50, B75R25, and B100R0: indicate the percentage of blue (B) and red (R) light; DW: dry weight. All values in the table are expressed as mean ± standard error (n = 3). Means with different letters are significantly different at the p < 0.05 level according to Tukey’s honestly significant difference test.
