WL	24.5 ± 0.38b	19.9 ± 0.17b	52.8 ± 1.64b	124.0 ± 9.54a	6559.8 ± 707.74a
BL	29.1 ± 0.36a	24.2 ± 1.07a	74.1 ± 1.52a	90.1 ± 4.86b	6668.9 ± 377.06a
GL	24.7 ± 0.71b	17.2 ± 0.69c	14.3 ± 1.56d	66.7 ± 3.18c	960.1 ± 146.11c
RL	28.9 ± 0.29a	18.1 ± 0.85c	48.8 ± 0.36c	71.0 ± 6.62c	3468.8 ± 346.75b

Different letters indicate significant differences (P < 0.05) between LED light treatments according to ANOVA and LSD test, n = 3. LED lamps used: WL, white light; BL, blue light; GL, green light; RL, red light.
