“…The soil substrata had as much inÑu-ence as the organic matter or other soil parameters and the concentrations in the soil were poorly correlated with those of the plants (Alonso 1994). (Fried and Broeshart 1967 ;Knezez and Ellis 1980 ;Jones and Thomas 1987 ;Garci a et al 1992), in some cases below the optimum for plant growth reported by Rains (1976).…”

“…Nevertheless, because of the high background in the X-ray spectrum due to bremsstrahlung radiation, the semi-quantitative or quantitative localization of trace elements with the electron microprobe is clearly out of the question. Yet a knowledge of the localization of the trace elements Zn, Fe, Cu and Mn would be an important adjunct to physiological studies because of their role as co-factors in the activation of key enzymes involved in seed germination (Rains, 1976).…”

SUMMARYA scanning proton microprobe has been used to determine quantitatively the distribution of Mn, Zn and other elements in the mature wheat seed {Triticum aestivum cv. Gamenya). Both X-ray and nuclear scattered proton data were collected during the irradiation of a 40/im-thick longitudinal section, and these were used to calculate absolute elemental concentrations for the various features of interest in the embryo region. Elemental maps were collected for a number of transverse and longitudinal sections (obtained from several seeds), but comprehensive analytical information was collected from one typical longitudinal section only. In the embryo, the concentration (by dry weight) of Mn was highest in the radicle (1400 +200/

“…Manganese deprivation in algae is known to cause chlorosis and to interfere with the maintenance of the chloroplast membrane structure and with the electron transport of Photosystem I1 (L'Kelley 1974, Rains 1976. Cadmium toxicity as analysed by competitive inhibition with manganese showed a similar effect on D. salina: chlorosis and cell death.…”

The unicellular halotolerant alga Dundiella s a l~n a was exposed to different concentrations of cadmium in the range 9 to 135 PM. Chlorosis was observed at 25 FM cadmium, and inhibition of cell division was established at 45 uM cadmium. Blosynthesis of the cellular osmoregulator, glycerol, was not affected by cadmium toxicity throughout the concentration range. Cadmium toxlcity was found to be antagonized by low concentrations of manganese. Michaehs-Menten analysis of substrate (Mn2+)
