Table II. Mean LRU values of the plant species used in this study and measured under low, moderate, and high light intensities (179, 352, and 1,889 μmol m−2 s−1, respectively), approximately 500 pmol mol−1 COS and approximately 400 μmol mol−1 CO2, temperature of approximately 23°C, and RH of approximately 75%.
Values represent means (±sd) of three to four measurements on different leaves.
