Elevated CO 2 (eCO 2 ) increase plant biomass and might lead to nutritional losses. The results showed that eCO 2 under Fe-deficiency stimulates root dry weight from 0.37-0.80 g plant −1 and shoot dry weight from 0.82-2.10 g plant −1 , without compromising root/shoot ratio. Besides, eCO 2 improved t...
