Specific activities and isoenzyme multiplicities of glutamic dehydrogenase, esterase, peroxidase, acid phosphatase, acid and neutral invertases were determined in a diploid, a triploid and a tetraploid sugar beet variety. The different ploidy status was accompanied by variations in the level of activity of glutamic dehydrogenase, peroxidase and invertase. Polyploidy induced a number of isoenzymes higher for peroxidase and lower for esterase, acid phosphatase and glutamic dehydrogenase. Specific isoenzyme bands characterised the invertase of the triploid variety.
