Taken per halfleaf). Initial SPAD values in sugar beet chlorotic leaves were 11.five 1.5.2fold (Figure 3B). In the end of your experiment, the treated distal areas had a 9fold SPAD raise with respect towards the initial values. Nonetheless, the regreening of your leaf surface was not homogenous (Figure 4B). The untreated basal a part of treated leaves and both parts of the untreated chlorotic controls had only minor SPAD increases throughout the time with the experiment. In all chlorotic and green untreated leaves, the SPAD values from the distal component had been usually greater (221 ) than that with the basal component (not shown). Also, some but not all leaves showed necrosis symptoms close to the border from the untreated basal aspect (Figure 4C). Ironsufficient control green leaves also had a SPAD value enhance throughout the experimental period (around 45 and 30 for the basal and distal leaf parts, respectively; Figure 3B).www.frontiersin.orgJanuary 2014 | Volume 5 | Report two |ElJendoubi et al.Foliar fertilization of Fedeficient leavesTable 1 | Concentrations of macro (N, P Ca, Mg, and K; in DW) and , microelements (Fe, Mn, Cu, and Zn; in g g1 DW) in basal and distal parts of Fedeficient peach tree leaves either not fertilized or eight weeks just after the first remedy with 2 mM FeSO4 and 0.1 surfactant.

Also, the basal untreated a part of fertilized leaves had slight Fe increases when when compared with the basal a part of untreated leaves, despite the fact that the differences had been only significant at p 0.ten. The rest of mineral components analyzed had been not impacted by Fe fertilization (Table 1). Calcium, N, and Mn concentrations tended to be distinctive within the basal and distal components (Ca and Mn being additional abundant within the basal component and N becoming a lot more abundant within the distal components).
