Objective: Based on the cultivation under the crown of Atractylodes lancea was better than the open field cultivation
different light experiments were carried out to investigate effect of different light qualities on the growth and the volatile oil content of A. lancea. Method: Six different light quality groups were set up
which included CK (blank group)
red light group
blue light group
red-blue (9:1) group
red-blue (6:1) group and red-blue (3:1) group
9 months later
sampling analysis was carried out. Result: The biomass (23.18 g) and total content of four essential oil components (3.74%) of A. lancea were the highest under red-blue (9:1) light conditions;followed by red-blue (6:1)
the biomass was 18.32 g and the total content of four essential oil components was 2.97%.In addition
the net photosynthetic rate (Pn)
transpiration rate (Tr)
stomatal conductance (Gs) and intercellular CO2 concentration (Ci) of red-blue (9:1) group were higher than those in other treatments
and most of them had significant differences.The activities of antioxidant enzyme[superoxide dismutase (SOD)
peroxidase (POD)
reduced glutathione (GSH)
reductive ascorbic acid (AsA) and catalase (CAT)] under different light quality groups were higher than those in the blank group
and most of them had significant differences.The malondialdehyde (MDA) content in red-blue (9:1) group was significantly lower than in the blank group. Conclusion: The results show that red-blue (9:1) illumination condition is most suitable for the growth and development of A. lancea
which provides new cropping patterns for improvement of yield and quality of this herb.
