Abstract:
The mineral nutrition of L. albus and L. angustifolius was studied under nutrient-sufficient conditions in sand culture. Mineral accumulation by both species was closely synchronized with dry matter accumulation. Fruits acquired major proportions of the nitrogen, phosphorus, potassium, magnesium and zinc of both species. Leaflets were major sites of accumulation of calcium, iron and manganese; stem and petioles accumulated substantial amounts of potassium, phosphorus, magnesium, copper and sodium. Intensities of intake of calcium, magnesium and iron by roots of L. angustifolius were higher than in L. albus. The situation was reversed for sodium. Cotyledon reserves of nitrogen, phosphorus, potassium and zinc were mobilized to seedling parts with 85
