Abstract


This paper deals with a preliminary investigation of ONP originating from tumour and callus tissues of Nicotiana tabacum. DNP preparations from tumour tissue contained on the average: 54.88% of protein, 38.4% of DNA and 2,9% of RNA. The N/P ratio value fluctuated within the limits 4.8—5.8. The respective mean values for DNP preparations from callus tissue were: 57.3; 21.6 and 13.l%. The NAP ratio was 4.7-6.6.
