| Outline of Final Research Achievements |
In the present study, the diversity of element accumulation was widely investigated in terms of variation by genetic factors, chemical forms and translocation in plant, and soil-plant interaction. Variation in foliar concentration among different species (approximately 850 species) tended to be small in essential elements but large in nonessential elements. Variations in the chemical form of aluminum in leaves of various aluminum accumulators was small, and the common form of Al was detected. In leaves of soybean, concentrations of phosphorus, potassium, and cupper decreased and those of many other elements, particularly molybdenum, increased with aging. The correlations of element concentrations between leaf and soil (available concentration) were determined in each element and in each species. Only some elements showed positive correlations under phylogenetic influence.
