Data were collected 5 weeks after the start of treatment.
Light intensities during the light period were as follows: B, 100 mol m−2 s−1; and B + R, 75 mol m−2 s−1 (B) + 25 mol m−2 s−1 (R).
Light intensities of the NB with B and FR were 20 mol m−2 s−1.
Data are represented as the mean ± SE (n = 9).
Values followed by the same lower-case letter did not differ significantly (p < 0.05) by Tukey’s honestly significant difference test.
