“…5B) also provides further evidence against the postulated hypothesis of Fe inactivation. Therefore, we suggest that the reported regreening of chlorotic leaves after spraying with citric acid (Tagliavini et al, 2000;Kosegarten et al, 2001) may be explained by the effect of citric acid in strongly extracting Fe bound in the cell walls, thereby increasing soluble Fe III citrate in the leaf apoplastic fluid, rather than by the postulated enhanced reduction of Fe III and, thus, Fe uptake into the symplast due to lowering of apoplastic pH (Kosegarten et al, 2001).…”

It has been hypothesized that nitrate (NO 3 Ϫ ) nutrition might induce iron (Fe) deficiency chlorosis by inactivation of Fe in the leaf apoplast (H.U. Kosegarten, B. Hoffmann, K. Mengel [1999] Ϫ supply (up to 40 mm) did not affect the relative distribution of Fe between leaf apoplast and symplast at constant low external pH of the root medium. Although perfusion of high pH-buffered solution (7.0) into the leaf apoplast restricted 59 Fe uptake rate as compared with low apoplastic solution pH (5.0 and 6.0, respectively), loading of NO 3 Ϫ (6 mm) showed no effect on 59 Fe uptake by the symplast of leaf cells. However, high light intensity strongly increased 59 Fe uptake, independently of apoplastic pH or of the presence of NO 3 Ϫ in the apoplastic solution. Finally, there are no indications in the present study that NO 3 Ϫ supply to roots results in the postulated inactivation of Fe in the leaf apoplast. It is concluded that NO 3 Ϫ nutrition results in Fe deficiency chlorosis exclusively by inhibited Fe acquisition by roots due to high pH at the root surface.When grown on highly calcareous soils, most plant species of the so called Strategy I type (Marschner and Rö mheld, 1994) respond to lack of iron (Fe) by developing characteristic symptoms of Fe deficiency chlorosis, primarily in young leaves. The concentration of Fe expressed on a dry weight leaf basis and the amount of Fe per leaf frequently decreases in chlorotic leaves, although the Fe concentration can sometimes be the same or even higher in chlorotic leaves as compared with green ones, as has been reported in field-grown woody plants ("the chlorosis paradox"; Morales et al., 1998;Rö mheld, 2000;Nikolic and Rö mheld, 2002). Various soil factors (e.g. CO 2 , ethylene, low temperature, high water content, and drought) resulting in severe inhibition of root growth might be responsible for triggering a restriction in leaf expansion growth, which in turn elevates the Fe concentration in these chlorotic leaves as a consequence of the diminished dilution of Fe concentration (Rö mheld, 2000, and refs. therein). This explanation would appear to account for the phenomenon of the "chlorosis paradox" that occurs occasionally under field conditions and is always associated with restricted leaf expansion growth. On the other hand, as has been hypothesized by Mengel and coworkers for many years, the higher Fe concentrations in the leaves of chlorotic plants could be caused by an increase in the pH of leaf apoplast induced by bicarbonate (HCO 3 Ϫ ) or nitrate (NO 3 Ϫ ) or both of these ions in the soil solution of calcareous soils (Mengel, 1994). These authors argue that because a high leaf apoplastic pH depresses the activity of Fe III reductase, less Fe 2ϩ can be transported across the plasma membrane into the leaf symplast, resulting in Fe deficiency chlorosis (Kosegarten et al., 2001). Despite this explanation, however, chlorotic plants with higher concentrations of Fe in younger leaves have never been found so far in nutrient solutions under controlled environmental...

“…That different species may obtain Fe from siderophares, phytosiderophores, and other organic complexes is documented in closely controlled conditions, but their significance is less understood in soil culture (Bar-Ness et al 1991;Hopkins et al 1992b;Tagliavini et al 2000;Crowley 2001;Tagliavini and Rombola 2001). Kamal et al (2000) reported reduced chlorosis symptoms in guava seedlings intercropped with sorghum [Sorghum hieo/-or (L.) Moench] or maize and Tagliavini et al (2000) showed that the presence of Poa spp., Lotium spp., and Festuca spp., along pear tree rows showed promise in preventing Fe chlorosis.…”

“…Citrate and malate exuded by the roots of calcicole plants (plants growing in alkaline soils) enable them to extract P and Fe from such soils (Lopez-Bucio and Nieto-Jacobo 2000). Citric acid (CA) has been used as a foliar spray, alone or in combination with Fe sources, to help plants recover from iron chlorosis (Tagliavini et al 2000, Abadía et al 2002, Álvarez-Fernández et al 2004, Eidyan et al 2014. The use of CA alone or in combinations with salicylic acid (SA) and MA increased the essential oil production in sweet basil (Jaafari and Hadavi 2012a) and dill (Jaafari and Hadavi 2012b).…”

We evaluated the effects of spraying different concentrations of citric and malic acids on stock plants in the greenhouse prior to the propagation and rooting of rose (Rosa × hybrida 'Love Letter') cuttings. Malic and citric acids (3, 6 and 9 mM) were sprayed several times at 14-day intervals on rose plants in a commercial cut flower producing greenhouse. Single-node cuttings taken from flowering stems were rooted under misty conditions, and the rooting parameters including root count and dry root weight were measured. A distinct change was observed in rooting features in response to the applied organic acids. Malic acid significantly enhanced rooting at the intermediate concentration while retarding it at both the higher and lower concentrations. On the other hand, the effect of citric acid was best at the highest concentration applied. We conclude that in softwood cuttings taken from rose plants these organic acids can act as a potential alternative to the currently applied methods of promoting rooting.Ke y wor d s: bud-break, foliar spray, organic acids, rooting quality, Rosa × hybrida
