Fig. 5From: Differences in morphological and physiological features of citrus seedlings are related to Mg transport from the parent to branch organsCharacteristics of leaf net photosynthetic rate (Pn, a), stomatal conductance (gs, b), intercellular CO2 concentration (Ci, c), transpiration rate (Tr, d), photosynthetic water-use efficiency (PWUE, e) and SPAD value (f, n = 40) in citrus seedlings grown under conditions of Mg deficiency (-Mg) and sufficiency (+ Mg). Data are presented as mean ± standard deviation (n = 13). Different letters represent significant differences among organs between the Mg treatment groups at P < 0.05Back to article page
