Fig. 1From: Transcriptional and physiological analyses of short-term Iron deficiency response in apple seedlings provide insight into the regulation involved in photosynthesisa The field performances of M. hupehensis, M. halliana and M. baccata on the Loess Plateau in the Northwest of China. b Hydroponic seedlings performances of M. halliana and M. baccata under Fe deficient stress. Physiological parameters: (c) chlorophyll a content, (d) chlorophyll b content, (e) carotenoid content, (f) chlorophyll a/chlorophyll b ratio, (g) relative electrical conductivity, (h) proline content, (i) superoxide dismutase activity, (j) peroxidase activity and (k) ascorbateperoxidase activity of M. halliana under Fe-deficiency (-Fe) and Fe-sufficiency (CK)Back to article page
