Przebieg mitozy w korzeniach siewek pszenicy pod wpływem rubidu [Course of mitosis in root seedlings of Triticum aestivum L. under the influence of rubidium]

Abstract

The depresion of mitosis as a result of rubidium action illustrated by the lower frequency of mitosis was found in an investigation made on roots of wheat seedlings grown on a nutrient medium which the total amount of potassium or a half of it was replaced by rubidium. The lower mitotic activity was caused by limited number of nuclei beginning prophase and by a prolonged duration of metaphase.
