Photosynthetic limitations were evaluated in three important Brassica crops: B. rapa, B. oleracea and B. napus. Measurements of induction after a period of shade showed that net CO2 assimilation by B. rapa and B. napus saturated by 10 min. A new method of analyzing limitations to induction by varying intercellular [CO2] showed this was due to co-limitation by Rubisco and electron transport.
