Figure 6. Dynamics of photosynthetic photon flux density (PPFD) incident at the leaf surface for leaves in mid (L2) and bottom (L3) canopy positions in mite-infested (+M) and uninfested controls (–M) in Season 1. Measurements were taken in basal and distal leaf sections. Error bars 2 SEM, and asterisks indicate significance on mite effects: *P < 0.05, **P < 0.01, ***P < 0.001.
