Cultivar Union which, compared with cultivar Lubuski has a larger root system, was found to show a significantly higher RNase activity. The nodes of cv. Union show a lower RNase activity per gram of tissue fresh weight and a higher specific activity, in comparison with cv. Lubuski. The number of RNase isoenzymes in the roots of both examined cultivars is the same. No difference in the number of RNase isoenzymes between the nodes of the examined cultivars was found either. On the other hand, certain differences between the examined cultivars in some RNase isoenzymes activities were observed in the analysed parts of the plants
