Fig. 2 Light response curves (assimilation rate vs. photosynthetically active radiation) when of young asymptomatic leaves on control plants (C) or plants inoculated with Verticillium dahliae (V), Pratylenchus penetrans (P), or with both pathogens (P+V) in Exp. 2 at (a) 16 DAI and (b) 42 DAI. Each point is an average of four leaves (except treatment P+V in part b, where each point is an average of three leaves because the fourth plant died due to infection)
