METABOLIC RESEARCH OF PLUS PEDUNCULATE OAK (QUERCUS ROBUR L.) TREES
Biochemical investigations of «plus» pedunculate trees in comparison with control ones were carried out. Only peroxidase activity is measured at deep dormancy stage, while supplementary superoxiddismutase, cytochrome-c-oxidase, esterase activities are revealed during electrophoresis. Increase of NADH-dehydrogenase, cytochrome-c-oxidase, alkaline phosphatase, isocitratedehydrogenase activities were shown by «plus» oak trees and vice versa decrease of isocitratelyase, malic enzyme, laccase activities when compared to control ones. For the first time common and specific activities of oak thirteen enzyme of a number of metabolic cycles have been studied, isozyme analysis of fourteen enzymes was carried out. Increase or decrease of the number of enzymatic activity zone during leaf ontogenesis were shown. Isozyme set for genetic polymorphism were suggested for investigation. The reason of biochemical difference origin between «plus» and control pedunculate oak trees is being under discussion.
