Light enhanced the growth of tea seedlings but the amount of caffeine produced in light was almost identical to that in the shade, indicating that more synthesis and/or less degradation of caffeine Occur(s) in shaded seedlings. Administering [N1-methyl-14C]-caffeine caffeine to tea shoot tips showed that light promotes the degradation of caffeine only slightly.
