초록

The variation of glucosinolates (GSLs) in Chinese cabbage (‘Sinhongssam’) (Brassica rapa L. spp. pekinensis) cultivated under lights to control plant growth conditions was evaluated at different development stages. Under experimental conditions in plant factory system, plant growth conditions including light, temperature, and nutrients were designed to enhance GSLs. The variation of glucosinolates (GSLs) in Chinese cabbage (‘Sinhongssam’) (Brassica rapa L. spp. pekinensis) cultivated under lights to control plant growth conditions was evaluated at different development stages. Under experimental conditions in plant factory system, plant growth conditions including light, temperature, and nutrients were designed to enhance GSLs. The contents of GSLs were quantified in Chinese cabbage according to different light sources (Red+White, RW; Red+Blue+White, RBW, Fluorescence lamp, FL) at development stages (28, 42, and 56 days after sowing, DAS) using HPLC. Nine GSLs including five aliphatic (progoitrin, sinigrin, glucoalyssin, gluconapin, and glucobrassicanapin) three indolyl (glucobrassicin, 4-methoxyglucobrassicin, and neoglucobrassicin), and one aromatic (gluconasturtiin) GSLs were identified based on peak retention time in previous results of our laboratory. GSL contents were higher in RBW (36.55) and lower in FL (15.24 μmol/g DW). Results revealed that GSL contents were higher under controlled photoperiods (20/4 h) (58.35 μmol/g DW) and controlled light intensity (160 μmol/m2/s) (34.02 μmol/g DW), respectively. Lower amount of progoitrin and comparatively higher amount of glucobrassicin and gluconasturtiin was noted in Chinese cabbage cultivated under FL light (2.38, 9.82, and 2.10) at 42 DAS, photoperiod 20/4 h (3.16, 2.52, and 1.30) at 28 DAS, and light intensity at 130 μmol/m2/s (2.28, 2.24, and 1.51 μmol/g DW) at 42 DAS. Therefore FL light, photoperiod (20/4 h), and light intensity (130 μmol/m2/s) were considered as most suitable for the enhancement of GSLs in Chinese cabbage.
