Abstract: Calli were induced from the mature seed of tea cultivar ‘Longjing 43’ (C. sinensis cv. Longjing 43) using different light spectrum qualities. The effects of different lights on the tea polyphenol (TP) contents and the activities of antioxidantive enzymes (superoxide dismutase and catalase) in calli were analyzed. The results showed that the TP content, superoxide dismutase (SOD) activity and catalase (CAT) activity of the callus that treated with different light spectrum qualities varied with light quality and treatment time. Calli grew better under blue light than other treatments. The TP content of each treatment increased from 1~10d and reduced from 10~20d. The TP content under blue light was lower than the control while that under red light was much higher than the control, simultaneously green and yellow light had insignificant influence. The activity of SOD under white light was significantly higher than other treatments, while that of red light was significantly lower. The activity of CAT under white light was also significantly higher than other treatments. However, green and yellow light may not be conducive to the synthesis of CAT.
