Estimation of Perspectives of Sapling Development of <i>Quercus robur</i> L. in the Wood Coenoses of Moscow Region

Abstract

The perspectives of transition of the immature and virginal saplings of Quercus robur L. to the A1 and A2 canopy sublayers have been analyzed. The studies have been conducted in the different forest types within the Southern Moscow region. For the estimation of the phytosociological role an individual could claim we applied morphometric and architectural methods. We measured height, trunk diameter, crown projection, calendar age and lengths of five trunk increments in a row. We considered growth habit, configuration and branching of the trunk and of the branches themselves. Four degrees of an individual’s prospect have been identified. 0 – an individual will not go beyond the level of low shrubs. 1 – an individual will reach the level of high shrubs and can start fruiting. 2 – an individual will reach the A2 canopy sublayer. 3 – an individual will reach the A1 canopy sublayer. From the degree 0 to the degree 3 an increase in the values of the trunk increments and branching intensity was noted.
