Abstract:
The two-year-old Atractylodes lancea seedlings were used as materials,three illumination groups were simulated in the phytotron,SCK (12 hours),S1 (10.5 hours) and S2(9 hours).The effects of shortening photoperiod on physiological,biochemical and photosynthetic parameters of Atractylodes lancea were explored,in order to provide a reference for the cultivation and light management of Atractylodes lancea seedlings.The results showed that the CAT activity,POD activity,SOD activity,the contents of proline and soluble protein were higher than those of SCK in short photoperiod treatment group for most of the treatment time.And the chlorophyll content and Pn,Gs decreased and the Ci increased.These results implied that different light period directly affects the physiological activity and biomass accumulation of Atractylodes lancea seedlings.Excessive shortening photoperiod during rhizome growth period can inhibit the growth and development of Atractylodes lancea.
