Variation of Photosynthesis, Fatty Acid Composition, ATPase and Acid Phosphatase Activities, and Anatomical Structure of Two Tea (Camellia sinensis (L.) O. Kuntze) Cultivars in Response to Fluoride

Table 1

Fatty acid composition in leaves of PY and FD after 2 weeks of fluoride (F) treatments. Contents are given as percentage of total fatty acid weight. Data are the mean of four replicates. Minor fatty acids less than 1% of the total amount are not shown. Fatty acids are abbreviated as the number of carbon atoms followed by the number of double bonds in the fatty acid.
