Tea shoots from twenty‐year‐old tea plants (cv. Jinxuan) sampled at two different times (The duration of the experiment was 2 weeks from the 5 November 2019 to the 19 November 2019; the 24 April 2020 to the 8 May 2020) were applied to study the effect of shade treatment on the subcellular distributions of L‐theanine and L‐glutamine. n.d., not detected.
