Morphological and Macroanatomical Indicators of Long-Term and Current State of Trees of Quercus Robur L.
The study’s purpose was to examine the conjugacy of the dynamics of morphological and macroanatomical indicators of the long-term and current states of oak trees. The data were collected in upland and floodplain oak groves on the southern border of the forest-steppe zone. The average dynamics of the groups of 10 most developed oak trees each was studied as a model of well-sunlit urban trees. The indicators used are nonspecific, which makes it possible to assess the complex impact of the factors, acting in urban conditions.
A correlation between the 25–35-year cyclical dynamics of the crown development and the number of vessels rows of the radial increment of stem earlywood as indicators of the long-term state of oak trees. The stages of damage and restoration of crown foliage were compared with the extremes of 8–12-year cycles of the number of vessels rows of stem earlywood as indicators of the current state of oak.
The superposition of the minimums of 25–35- and 8–12-year cycles of oak trees state increased the risk of damage and death. In both types of oak groves, the cyclical state of the oak was similar, and its trends differed depending on the age and density dynamics of the stands. Based on the proposed approach, retrospective and predictive assessments of the long-term and current state of oak trees are possible.
