Standard errors in the brackets. LSD: least significance difference for P = 0.05; n.s.: not significant.

B100: only blue light; R100: only red light; B75R25: blue 75% + red 25% of total PFD; B50R50: blue 50% + red 50% of total PFD; B25R75: blue 25% + red 75% of total PFD; WIDE = wide spectrum, composed of blue 18% + red 18% + intermediate wavelengths for the remaining 64% of total PFD.
