^a The light qualities are R/B (88.9% red+ 11.1% blue), R/B/P (80.0% red+ 10.0% blue+ 10.0% purple), R/B/P/G (72.7% red+ 9.1% blue+ 9.1% purple+ 9.1% green), W (12.7% red+ 3.9% blue+ 83.4% green)

^b mean ± standard deviation, n = 3

^c Any two means within a column not followed by the same letter are significantly different at P < 0.05 by ANOVA on Duncan’s multiple range test

^*, ^** mean significant at 0.01 < P < 0.05 and P < 0.01, respectively
