Polyakova L.V., Gamayunova S.G., Zhurova P.T., Litvinenko V.I. Biochemical specific of European oak trees with dry crown // Forest Science (Lesovedenie). 2014. No 4. С.28-35. The trees of the 56-year old oak stand including those having dry crown and lacking desiccation features have been tested biochemically. The neighboring 200-300 years old trees lacking drying crown features served as the control. We focused the study on protein contents in leaves, and chose flavonols and tannins out of secondary metabolites. The higher activity of dominant pests Altica quercetorium and Erannis defoliaris in the stand have been shown to be related to lower proteins and condensed tannins concentration compared to old trees. English oak, primary and secondary metabolites, desiccating trees.. |
