An electrophoretic and cytological study of hybridisation between Aconitum napellus ssp. skerisorae (2n= 32) and A. variegatum (2n= 16). I Electrophoretic evidence

Abstract

The variability of six enzymes in pure and mixed populations of Aconitum napellus and A. variegatum, both from the Tatra Mountains was analysed by means of electrophoresis on starch and polyacrylamide gels. The enzymes differentiating the studied species are: glutamate dehydrogenase, isocitrate dehydrogenase, esterases and peroxidases. A group of plants was isolated with phenotypes intermediate between A. napellus and A. variegatum. Among them were most probably both F1 and introgressive hybrids.
