Shown in Table 1. In Fedeficient leaves, the Fe signal was a lot more intense inside the palisade parenchyma in comparison with the rest of leaf tissues (Figure 7B), whereas in control leaves the Fe signal was extra intense in the vascular tissue as well as the spongy parenchyma (Figure 7A). Within the distal sections of Fefoliar fertilized leaves, far more intense Fe signals were present in palisade, spongy parenchyma and upper epidermis and to a lower extent within the vascular area (Figure 7D), whereas inside the soilfertilized ones the highest concentration was within the reduce epidermis (Figure 7C). Also, some increases inside the intensity of the Fe signal occurred in the vascular area in the basal untreated leaf portion (Figure 7E).Alterations IN CHL FLUORESCENCE IN PEACH TREE LEAVES WITH IRON FERTILIZATIONChl fluorescence was imaged and measured in severely and moderately Fedeficient, Fesufficient and Fefertilized peach tree leaves 1 week following the initial foliar Fe application (Figure eight).

Signals are suggests in g Fe g1 DW (SE).a neoxanthin lutein carotene VAZ in peach tree leaves, and carotene Chl b Chl a neoxanthin lutein VAZ in sugar beet leaves. These changes have been accompanied by decreases inside the (ZA)/(VAZ) ratio in each species, also as by compact increases in FV /FM in peach tree leaves. Iron deficiency has been shown to induce decreases in FV /FM and PSII in sugarbeet, peach and pear (Nedunchezhian et al., 1997; Abad et al., 1999; Morales et al., 2000), and equivalent changes in photosynthetic pigments and Chl fluorescence soon after Feresupply towards the nutrient answer have been reported to take place in sugar beet (Larbi et al.2-(2,2-Difluorocyclopropyl)acetic acid web , 2004). The effects of foliar Fe treatments on the basal, untreated parts of chlorotic Fedeficient leaves have been quite limited.
