Биохимическая характеристика многовекового насаждения и 55-летней культуры дуба черешчатого, отличающихся устойчивостью к листогрызущим насекомым
Aims. Decline of common oak plantations in last 40–50 decades is a serious problem in many countries. In eastern part of Ukraine there were observed two neighboring common oak plantations: 200–300-year old health trees and 55-year old culture with 15–16 % of decaying trees. Methods. Biochemical pecu...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Aims. Decline of common oak plantations in last 40–50 decades is a serious problem in many countries. In eastern part of Ukraine there were observed two neighboring common oak plantations: 200–300-year old health trees and 55-year old culture with 15–16 % of decaying trees. Methods. Biochemical peculiarities of these plantations were studied for several leaf traits: common protein content (Pt), condensed tannins (CT) and hydrolysable ones (HT). The degree of herbivore insects’ activity was studied also. Results. It was found the much more intensive damage in 55-year old culture by two dominance species of herbivores – Altica quercetorum and Erranis sp. The specialist (A. quercetorum) prefer trees with high content of Pt in leaves and low content of HT. The generalist (E. sp.) prefer opposite proportion of these groups of compounds in leaves. The most stable trees were found in 200–300-year old plantation. Conclusions. The most special peculiarity concerned the content of CT. Their content in leaves of old plantation trees was 200–250 % higher compared to 55-year old culture.
