Mengel, W. Bubl and H. W. SchererInstitute of Plant NutritionJustus Liebig UniversityGiessen, West GermanyABSTRACTThe objective of the investigation was to examine whether ironchlorosis in grape vine grown on calcareous soils was related tothe Fe distribution in the leaf.Leaf samples collected from three different sites showed inmost cases higher Fe contents in the chlorotic leaves as comparedwith healthy leaves. The solubility of leaf Fe in diluted HC1, how-ever, was lower in chlorotic leaves than in green leaves.Enzymatic dissolution of leaves into vascular tissue, inter-costal cells and chloroplasts revealed that the Fe content in theintercostal cells of green leaves was significantly higher than inthe intercostal cells of chlorotic leaves. In addition, the inter-costal cells of chlorotic leaves had extremely high Ca and P con-tents.The P content of green and chlorotic leaves was not related tothe level of available P 1n the soil. It is, therefore, concludedthat the high P content in chlorotic leaves is the sequence and notthe cause of Fe chlorosis.715Copyright 1984 by Marcel Dekker, Inc. 0190-4167/84/0705-0715$3.50/0Downloaded by [Moskow State Univ Bibliote] at 16:41 26 August 2013 716 MENGEL, BUBL, AND SCHEREROn each of the three sites investigated, higher clay contentswere found under chlorotic grape vine plants than under healthyones. It is assumed that because of this higher clay content, soilcompaction may occur, resulting in an accumulation of C02 and in anincrease of the HCO3- concentration in the soil solution.INTRODUCTIONAccording to recent investigations Fe chlorosis ts occurringvery often in connection with high concentration of HCO3" in thesoil (Boxma , Kovanci et al. 8). Although it has been shown that theuptake and translocation of iron in the plants is affected by HCO3"(Rutland and Bukovac^), to control chlorosis more information isrequired about the process which is leading to the HCO3" inducedchlorosis. Frequently total Fe in chlorotic leaves of plants grownon calcareous soils is higher than the Iron content in green leaves(Bubl3), in contrast to the HC1 soluble Fe which is lower in chlo-rotic leaves as compared with green leaves (Jacobson', Bucher^).The objective of the investigation presented here was to findout whether HCO3" induced chlorosis in grape vine was related tothe distribution of iron in the leaves. For this purpose chloroticand green leaves of vine plants were sampled and analyzed for dif-ferent Fe fractions: Total Fe, HC1 soluble Fe, Fe of the inter-costal cells (cells between leaf veins), Fe of the main leaf veins,and chloroplast Fe.MATERIALS AND METHODSIn 1979 leaf samples from chlorotic and healthy vine plantswere collected from the site 'SpieBheim' and in 1980 from the sites'SpieBheim', 'Iphofen' and 'Nierstein1. These sites are susceptibleto Fe chlorosis of vine. On each site leaf samples were taken from20 green and 20 chlorotic vine plants, respectively. From each ofthese plants the 10 youngest leaves of two shoots were collected.The leaf samples were frozen immediately in liquid nitrogen and thenstored in a deep-freezer at -18C.Five samples were used for the determination of the mineralcontent of the leaves, while the other 15 samples were used for theenzymic dissolution of the leaves in different fractions,From the same sites where the leaf samples were collected, in1980 soil samples were taken underneath 10 chlorotic and 10 healthyvine plants, respectively. Each 10 subsamples were combined to onesample. On the sites 'SieBheim' and 'Iphofen1, soil samples weretaken from the depth 0 to 40 cm and 40 to 80 cm, while in (N1erste1n(samples were taken from the depth 0 to 20 cm and 20 to 60 cm.Downloaded by [Moskow State Univ Bibliote] at 16:41 26 August 2013 IRON CHLOROSIS 717Available soil P and K were analyzed by the CAL method, thecommon method used in Germany for the estimation of available P andK. The extractant is consisting of a mixture of Ca lactate, NH4lactate and acetate, pH 4,1 (Schuller^). Iron, Mn, Zn, and Cuwere extracted by DTPA (Lindsay and Norvell9), Carbonate was anal-yzed according to the method of Scheibler^-5 and HCQ3" according tothe method of B ^The mineral content of the leaves was analyzed after wet ashingof the ground leaf samples by atomic absorption. Phosphate was de-termined according to the vanadate-molybdate method. For the deter-mination of HC1 soluble Fe 0.5 g of the dried and ground leaf mate-rial was extracted with 20 ml of 0.5 N HC1 and 1.0 N HC1, respec-tively, for 30 min, so that two different HC1 soluble fractions wereobtained, one by the extraction with 0.5 N and one by the extractionwith 1.0 N HC1. Iron was determined by atomic absorption.Enzymic Dissolution of_ the CellsFor the separation of the cells two samples (= 30 leaves total-ly) were combined and thawed slowly in a refrigerator. Then themiddle of the five main leaf veins was isolated. In this fraction,which is called 'leaf veins', Fe, Mn, Zn, Cu, Ca, and P were deter-mined. The rest of the leaves was cut into small pieces and trans-ferred into 10 Erlenmeyer flasks. Then 20 ml of solution No, 1 wasadded.Soln. 1: 1% mazerozyme (mixture of pectinase, hemicellulaseand cellulase)2% polyethyleneglycoll 400020 mmolar HEPES buffer0.65 molar mannitpH 5.8The addition of the buffer was necessary to stabilize the pH,which declined about 0.5 pH units in 2 hours. After 2 h the pH wasreadjusted to pH 5.8 by the addition of 1 N NaOH. The samples wereshaken for 4 hours in a waterbath at 25C and afterwards poured on a100 urn sieve. After washing with 0.65 M mannit the filtrate wascentrifuged. The sediment consisted mainly of intercostal cells.This fraction, called 'intercostal cells' in the following was ana-lyzed for Fe, Mn, Zn, Cu, Ca, and P. The fraction, which did notpass the sieve, was transferred to Erlenmeyer flasks. To this frac-tion 20 ml of solution No. 2 was added.Soln. 2: 1% cellulase Onozuka SS*2% polyethyleneglycoll 4Q0Q20% mmolar HEPES buffer0.3 molar mannitpH 5.2*Firma Welding and Co., Hamburg, West GermanyDownloaded by [Moskow State Univ Bibliote] at 16:41 26 August 2013 718 MENGEL, BUBL, AND SCHEEERThe samples were shaken 1n a water bath at 36C for 4 hours andthen poured on a 100 urn sieve.

The differencesbetween 1 N HC1 soluble Fe of chlorotic and green leaves were sig-nificant for all samples. The amount of Fe extracted by 0.5 N HC1was nearly as high as that extracted by 1 N HC1. The differencesbetween the Fe contents in the veins of healthy and chlorotic leaveswere small and not significant. The Fe content in the intercostalcells of green leaves was significantly higher than in the inter-costal cells of chlorotic leaves. The Fe contents of the chloro-plasts differed very much between the various sites. There were nomajor differences between the Fe content in chloroplasts of greenand chlorotic leaves. However, the chlorotic leaves contained lesschloroplasts.As can be seen from Table 2, P concentrations in whole leaveswere significantly higher in the chlorotic samples as compared withthe green ones. The same was true for the P concentrations in theintercostal cells. Also, the Ca concentrations in the chloroticintercostal cells were significantly higher than in the green inter-costal cells. Concentrations of Mn, Zn, and Cu were mainly higherin chlorotic samples than in green samples (Table 3).TABLE 2Ca- and P concentrat ions in leaves and l e a f - f r a c t i o n s of green andch lo ro t i c leaves.SpieBheim 1979 SpieBheim I960 Iphofen 1980 Iphofen 1980green chlorot, green chlorot. green chlorot. green chlorotWhole leafLeaf veinsIntercostalcellsChloroplastsWhole leafLeaf veinsIntercostalcells1.57 1.510.691.010.221.7C0.930.36*0.13 0.24% Ca, d.m.1.16 1.121.79 1.670.60 1.341.25 1.36% P, d.m.0.20 0.30***0.11 0.150.09 0.17Chloroplasts 0.85 0.71 C.59 0.56Comparison between green and.chlorotic leaves:* p = 5 %, ** p = 1 %, *** p = 0.1 %1.30 1.501.04 1.23*1.04 1.98*1.17 1.630.19 0.340.14 0.17*0.11 0.16*0.13 0.151.32 1.461.43 1.60*0.76 1.46*0.99 0.840.25 0.380.13 0.20*0.15 0.250.35 0.40Downloaded by [Moskow State Univ Bibliote] at 16:41 26 August 2013 720 MENGEL, BUBL, AND SCHERERTABLE 3Mn-, Zn- and Cu concentrations in leaves and leaf-fractions ofgreen and chlorotic leaves.Whole leafLeaf veinsIntercostalcellsChloroplastsWhole leafLeaf veinsIntercostalcellsChloroplastsWhole leafLeaf veinsIntercostalcellsSpieBheim 1979green chlorot.104-168050-196-721Chloroplasts 61Cnmparison between* **p = 5 %, P = 1***55-24*65***138-**301-***112158green arid***%, PSpieGheim 1980green chlorot.ppm Mn14098190, d.m.**192113**1402444 2870ppm Zn697291341ppm Cu8101696chlorotic= 0.1 %, d.m.***1397465*297, d.m.***1514***2499leaves:Iphofen 1980green chlorot.4433134784727969813121776**5730831***137***112887961211***2369Iphofen 1980green chlorot.14410719123595560--591686***195***154***1271973**80**68--7*10***2079The most important soil characteristics and nutrient contentsof the soil samples, which were taken underneath green and chloroticvine plants, are shown in Table 4.

This observation was made byBoxma2 for fruit trees. In our investigations all soils were richin carbonate and the pH was higher than 7. But although we foundhigh HCO3" concentrations on all the sites, there was no relation-ship between iron chlorosis and the HCO3" content. However, meas-uring the HCO3" concentration in a soil sample does not provide areliable information about the concentration of HCO3" in the rhizo-sphere and the HC03" uptake of plants. Because of the excretion ofCO2 and H by roots (Mengel and Malissiovasll), the HCO3" concen-tration in the rhizosphere of carbonate soils may differ consider-ably from the HCO3" concentration of the bulked soil. Enhanced C02production in the vicinity of the roots may lead to high HCO3- con-centrations in the rhizosphere.Especially HC03" can be accumulated under high soil moistureconditions on soils with a heavy texture. This holds true for ourinvestigations. Higher clay contents were found under chloroticvine plants than under green vine plants. These findings are con-sistent with results of Carter5 who also observed chlorosis on soilswith a high clay content.Investigations of Bubl^ with H C03 have shown that tPie rootsof vine plants take up HCO3-. It 1s therefore supposed that on cal-careous soil HCO3" is absorbed by vine plants and that HCQ3" directlyor indirectly affects the Fe transport into the intercostal cells.A similar effect has been observed with nitrate nutrition CMengeland Malissiovas^0). Probably an alkaline nutrition has a detri-mental influence on Fe mobility in vine leaves.The reason why HCO3" is hindering the Fe transport into theintercostal cells is not yet clear. Although the total Fe contentof the chlorotic leaves was at least as high as in green leaves oreven higher. HC1 soluble Fe was significantly lower in chloroticleaves as compared to green leaves. This confirms results of Jacob-son' and Mengel et a.1'.There was no relationship between the CAL - P content of thesoils and the P content of the leaf samples. But on all sites theP content in the whole leaves and in the intercostal cells, respec-tively, was significantly higher in chlorotic leaves than In thecorresponding samples from green plants. It 1s thus suggested thatFe chlorosis on calcareous soils is not caused by high soil P con-tents. The high P contents 1n the chlorotic leaves are rather theresult of a physiological Fe deficiency. The same holds true forthe high Mn, Zn, and Cu contents of the chlorotic leaves. Also,Bucher* and B00B et al.l found higher P contents in chloroticleaves. Our conclusions that the high P contents 1n chloroticDownloaded by [Moskow State Univ Bibliote] at 16:41 26 August 2013 IRON CHLOROSIS 723leaves are the result and not the cause of the Fe chlorosis areconsistent with the results of Mullner^ and Mengel et al .12,REFERENCES1.
