Analysis of correlations between biochemical traits, biometrical parameters and stability for Quercus robur L. trees in the cultures of different age
Journal Title: Лісівництво і агролісомеліорація - Year 2014, Vol 124, Issue
Abstract
Oak trees (Quercus robur L.) from different years old cultures were examined on biochemical traits (content of protein – PR, hydrolysable tannins – HD), biometrical parameters (diameter, height) and stability to phytophagous organisms. According to negative correlation between PR and HT there were three biochemical phenotypes established. The 1-st and 2-nd phenotypes are characterized with balanced content of both PR and HT (in agreement with their negative correlation structure). The 3-rd phenotype is determined as break of these correlation structure. The trees of the 1-st biochemical phenotype appeared to be the more resistant to phytophagous damage. The most vulnerable were the trees of the 3-d biochemical phenotype.
