  • Growth in daytime was estimated as the difference between photosynthesis (A) and C turnover, defined as the sum of the C in starch, sugars, organic acids, and amino acids turned over during the night. Growth at night was estimated as the difference between C turnover and respiration (R). The growth rates represent the growth per hour. Rg was estimated as growth rate × 0.2. Maintenance respiration was estimated as RRg. The original data and more information are available inSupplemental Data Set 3 online.
