The effect of Ca on Cu toxicity in runner bean plants (Phaseolus coccineus L. cv. Piěkny Jaś) grown hydroponically in nutrient solution was studied. The toxic effect of excess Cu on plants depends on their age and Ca content in the medium. Copper applied in excess to the plants at the early phase of leaf development strongly limits the uptake of Ca ions from the nutrient solution, particularly their translocation to leaves. Increased Ca content limits the inhibitory effect of Cu on leaf growth and decreases the content of chloroplast pigments to the level approximate to that of control. At this growth stage the effect of excess Cu is at least partially connected with limited Ca transport to leaves. At the intermediate leaf phase Cu-treated plants react slightly to changed Ca content. At the end of the primary leaf development increased Ca concentration in the medium intensifies senescence processes induced by excess Cu. The changes are partially connected with intensified water deficit. Increased Ca content in the nutrient solution limits Cu accumulation in the individual organs of Cu-treated plants. However, Cu accumulation in leaves is not decreased at a high level of Ca. Copper generally decreases Ca content in the youngest plants, whereas in the oldest ones only in the case of a low level of Ca in the nutrient solution.

Bean pericarp (Pericarpium phaseoli) is a pharmacopoeic plant material which exerts diuretic and antidiabetic activities, described in the Polish Pharmacopoeia VI. The presence of free aminoacid and arginine identified with TLC method, is one of the requirements the bean pericarp must fulfil to be classified as a pharmacopoeic plant material. The aim of this work was to describe the method which enables the identification of free peptic aminoacids occurring in the bean pericarp with the HPLC method and the Dabsyl chloride. The HPLC analysis of the extracts abtawved faom the. ^túca^ oí exatwcveà an à their cultivars avowed to identify the presence of a large number of free aminoacids.

The highest content of free aminoacids was found in the bean pericarp of the Piękny Jaś cultivar, the lowest content was found in the Blanka cultivar.
