“…It was observed that the concentration of malic acid, which is one of the organic acids in mandarine leaves, is higher than the concentration of citric acid. The total organic acid concentrations of some chlorotic leaves were higher than those of healthy leaves (Table 4; Iljin, 1951;Jungk et al, 1972;Nierhaus and Kinzel, 1970;Saatçi, 1990). A significant negative correlation between citric acid, an organic acid which is considered as an indicator of Fe deficiency, and CaC(>) in soil (0-30 cm) was found.…”

“…zwischen den Trockensubstanzertragen und dem Quotienten aus Malat und Citrat ergab sich ein positiver korrelativer Zusammenhang. Bei Untersuchungen iiber den Einflufi von Fe-Mange1 auf die Ionengehalte von Tomatenpflanzen wurde ebenfalls gefunden, daD das Malat : Citrat-Verhiiltnis mit sinkendem Ertrag abnimmt, hier allerdings auf Grund der relativ starkeren Zunahme des Citratgehaltes gegeniiber dem Malatgehalt ( Jungk et al 1972). Bisher ist unklar, o b dies die Ursache fur den beobachteten Ertragsriickgang ist oder lediglich die Folge einer Stoffwechselstorung, die ihrerseits den Ertragsabfall bewirkt.…”

“…Unter Fe-Mangel kommt es bei einigen Pflanzenarten zu erhohten Kalium-und verminderten Ca-Gehalten ( Wadleigh and Brown, 1952), zu v e d n d e r t e r Anionen-aber verstarkter Kationenaufnahme, ( Venkatraju et al, 1972;Jungk et al, 1972;van Egmond and Aktas, 1977), verstkkter H+-Abgabe an das Nahrmedium ( Venkatraju et al, 1972; van Egmond and Aktas, 1977) und einem Anstieg des Carboxylatgehalts, vor allem der Citronensaure (Iljin, 1951;Clark, 1968;de Kock and Morrison, 1958;Tiffin, 1966).…”
