Abstract
In the pathogen system Claviceps purpurea – rye, the parasite produces profound modifications. In order to study the alkaloids’ influence upon the mineral metabolism we have investigated the sodium, potassium, magnesium, calcium and silicon ions from the rye plants parasitized by Claviceps purpurea, as well as from rye plants treated with ergocryptine and ergotoxine solutions. The sodium, potassium and magnesium ions are found in different amounts, depending on the alkaloids that act upon the plant. The value of the potassium/magnesium report is higher than the one mentioned in references. There is a convergence of the manifestations for the calcium ions, depending on the predominant alkaloid that acts upon the plants. The value of the calcium/magnesium report varies between 1.12 and 0.27. In the presence of the parasite these values are reduced and they range according with the alkaloid type of the parasite (the lowest report was found at the ergocrystine type).
