Abstract
The total activity of malate dehydrogenas and isocritrate dehydrogenase was investigated in leaves of counterpart pairs from the three cytoplasmic male sterile (CMS) sources: H. annuus L., H. petiolaris Nutt and H. annuus L. ssp. lenticularis (Dougl.) Skll. Each pair had different genome composition. The multiple molecular composition of glutamate dehydrogenase and cytochrome oxidase in female reproductive organs of the same CMS sources was also studied. Results show an increase in the activity of the enzymes in the leaves of sunflower sterile forms. The three cytoplasm sources did not alter glutamate dehydrogenase composition in female reproductive sources in respect to quality and quantity. Cytochrome oxidase electrophoretic spectrum did not change under the influence of the CMS counter part H. petiolaris, but in counterparts with H. annuus and H. lenticularis cytoplasm the absence of two isoforms with equal electrophoretic mobilities was observed.
