“…These findings agree with the close relationships between leaf and soil Mg and Ca levels for container-grown oranges (Martin & Page 1965, 1969, and with positive correlations between leaf and Soil Mg levels, and between leaf Ca and soil Ca, pH, and P for Valencia oranges (Anderson & Albrigo 1977).…”

The level of exchangeable magnesium (Exch Mg) decreased in all treatments, but the decrease was greater at higher rates of fertiliser, presumably because of greater tree uptake. Strong, positive correlations were observed between leaf and soil levels of Mg, and between levels of Ca in the leaves and levels of Exch Ca, BS, pH, and Bondorff P in the soil. Leaf N levels increased significantly with increasing fertiliser rates, and tended to increase with time. Leaf P levels declined with increasing rate of fertiliser application in some orchards. Leaf K levels generally declined with time, the decrease being significantly greater at higher fertiliser rates. Leaf S levels also tended to decrease with time, but the decrease was significantly less at the high rate of fertiliser.

“…Mg depresses Mn uptake (Lohnis 1960;Maas et al 1969) and Cu and Zn can strongly inhibit the uptake of one another (Schmid et al 1965;Bowen 1969). However, in leaves collected in 1976, there was a moderately strong positive correlation (0.64) between Mg and Mn levels, and a very strong positive correlation (0.92) between Cu and Zn levels.…”

“…As discussed by Kochian (1993), uptake of Zn 2ϩ is likely to be a thermodynamically passive process, driven by the inwardly directed negative membrane potential across the plasmalemma, and low-temperature uptake inhibition is likely to result indirectly from a reduction in the membrane potential. Low-temperature-induced reduction in Zn 2ϩ up- take was reported previously for sugarcane leaves (Bowen, 1969), barley roots (Schmid et al, 1965), and wheat roots (Chaudhry and Loneragan, 1972). The dramatic inhibition of Zn 2ϩ uptake by Ca (Fig.…”

“…As a means of estimating Zn 2ϩ binding to wheat root cell walls, uptake was measured in intact roots exposed to low temperatures during the uptake period. Low temperature has been shown to inhibit uptake of Zn 2ϩ in barley (Schmid et al, 1965) and sugarcane (Bowen, 1969).…”

Durum wheat (Triticum turgidum L. var durum) cultivars exhibit lower Zn efficiency than comparable bread wheat (Triticum aestivum L.) cultivars. To understand the physiological mechanism(s) that confers Zn efficiency, this study used 65 Zn to investigate ionic Zn 2؉ root uptake, binding, and translocation to shoots in seedlings of bread and durum wheat cultivars. Time-dependent Zn 2؉ accumulation during 90 min was greater in roots of the bread wheat cultivar. Zn 2؉ cell wall binding was not different in the two cultivars. In each cultivar, concentration-dependent Zn 2؉ influx was characterized by a smooth, saturating curve, suggesting a carriermediated uptake system. At very low solution Zn 2؉ activities, Zn 2؉ uptake rates were higher in the bread wheat cultivar. As a result, the Michaelis constant for Zn 2؉ uptake was lower in the bread wheat cultivar (2.3 M) than in the durum wheat cultivar (3.9 M). Low temperature decreased the rate of Zn 2؉ influx, suggesting that metabolism plays a role in Zn 2؉ uptake. Ca inhibited Zn 2؉ uptake equally in both cultivars. Translocation of Zn to shoots was greater in the bread wheat cultivar, reflecting the higher root uptake rates. The study suggests that lower root Zn 2؉ uptake rates may contribute to reduced Zn efficiency in durum wheat varieties under Zn-limiting conditions.

“…Investigations of the forms of nutrient cations such as Fe, Cu, and Zn in leaf tissues of agronomic species (56,57) have shown these to be pr,esent as anionic complexes. Similarly, studies of the chemical forms of trace elements transported within the xylem (11,25,(37)(38)(39)(58)(59)(60)(61)(62) and phloem (63) show Ca, Fe, Ni, Mn, and Zn to be transported as organic complexes. In the case of nutrient ions, complexation may provide a basis for maintaining their mobility within the plant and allowing for their accumulation at sites of metabolic use.…”

The use of plants to monitor heavy metal pollution in the terrestrial environment must be based on a cognizance of the complicated, integrated effects of pollutant source and soil-plant variables. To be detectable in plants, pollutant sources must significantly increase the plant available metal concentration in soil. The major factor governing metal availability to plants in soils is the solubility of the metal associated with the solid phase, since in order for root uptake to occur, a soluble species must exist adjacent to the root membrane for some rinlte period. The rate of release and form of this soluble species will have a strong influence on the rate and extent of uptake and, perhaps, mobility and toxicity in the plant and consuming animals. The factors influencing solubility and form of available metal species in soil vary widely geographically and include the concentration and chemical form of the element entering soil, soil properties (endogenous metal concentration, mineralogy, particle size distribution), and soil processes (e.g., mineral weathering, microbial activity), as these influence the kinetics of sorption reactions, metal concentration in solution and the form of soluble and insoluble chemical species.The plant root represents the first barrier to the selective accumulation of ions present in soil solution. Uptake and kinetic data for nutrient ions and chemically related nonnutrient analogs suggest that metabolic processes associated with root absorption of nutrients regulate both the affinity and rate of absorption of specific nonnutrient ions. Detailed kinetic studies of Ni, Cd, and Tl uptake by intact plants demonstrate multiphasic root absorption processes over a broad concentration range, and the use of transport mechanisms in place for the nutrient ions Cu, Zn, and K. Advantages and limitations of higher plants as indicators of increased levels of metal pollution are discussed in terms of these soil and plant phenomena.The principal objectives of this review are to briefly describe the soil and plant factors influencing trace metal uptake by plants, and, with this information as a basis, illustrate some of the parameters which must be considered in using higher plants as indicators of increased levels of metals in the terrestrial environment.In order to utilize plants as monitors of metal pollution in the field, it is necessary to distinguish between uptake arising from natural metal sources and from pollutant sources. Metals from both natural and pollutant sources have the potential for being assimilated by the plant through foliar or root absorption processes. The importance of foliar absorption processes for several heavy elements has been discussed elsewhere (1, 2). Separation of the sources of metals taken up by roots is complicated by the mediating effect of soil properties and soil and plant processes. These effects may be illus-* Battelle, Pacific Northwest Laboratories, Richland, Washington, 99352. trated by examination of the concentration of metals in soil relative to po...
