Photosynthetic apparatus performance of oilseed rape plants at different days after exposure to nano-TiO₂.

Abstract

<p>A: net photosynthetic rate (Pn); B: stomatal conductance (Gs); C: intercellular CO₂ concentration (Ci); D: transpiration rate (Tr). Results are shown as means of four replicates. Means with the same lowercase letters are not significantly different at P<0.05. Vertical bars represent±SE.</p
