Data were collected 5 weeks after the start of treatment.
White (W) light was obtained by means of cool white fluorescent tubes, with light intensities of 150 mol m−2 s−1.
Light intensities of B, R, and FR were 39.1 mol m−2 s−1, 55.3 mol m−2 s−1, and 62.5 mol m−2 s−1, respectively.
Data are represented as the mean
±
SE (n = 14).
Values followed by the same lower-case letter did not differ significantly (p < 0.05) by Tukey’s honestly significant difference test.
