Fig. 6. Leaf carbon exchange rate (CER), leaf conductance to water vapor (gtw), total chlorophyll (Chl) concentration, and total Rubisco carboxylase activity of the fifth leaf below the apex as a function of days after emergence for Dara-5 and wild-type potato plants grown in growth chambers at photosynthetic photon flux (PPF) of 300, 600, and 900 µmol m–2 s–1. The Dara-5 chlorophyll and Rubisco data for the last sampling date in the 900 µmol m–2 s–1 PPF treatment are not shown because of a sampling error. Vertical bars represent ±1 SE of the mean (n = 8) where these exceed the size of the symbol.
