Description
Summary:The aim of this study was to evaluate the effects of different light quality of light emitting diode (LED) on the growth, concentration of chlorophyll and chlorophyll biosynthesis precursors of non-heading Chinese cabbage (Brassica campestris L.). Seedlings of the cultivar Te Ai Qing were cultured for 28 days under 6 treatments: red light (R), blue light (B), green light (G), yellow light (Y), red plus blue light (RB) and dysprosium lamp (CK). Lighting experiments were performed under controlled conditions (photon flux density 150 μmol m⁻² s⁻¹; 12 h photoperiod; 18–20 °C). The fresh and dry mass were the greatest under RB, which were significantly higher than other light treatments. The fresh mass under RB was almost twice higher compared to other light treatments. Plant height was highest under R treatment and was lowest under B. RB treatment also lowered the plant height significantly. The highest soluble sugar concentration was observed under B. The soluble protein concentration was the greatest under RB. The R treatment was adverse to pigment accumulation. The concentration of photosynthetic pigments and chlorophyll biosynthesis precursors were higher under RB. The RB treatment was beneficial to pigment accumulation.
