Abstract
Comparative observations of the growth dynamics of various trees planted in the arid conditions between the Volga and the Urals were carried out taking into account the current change of natural and climatic conditions. The conditions and causes of sudden changes of the growth rates of trees were analyzed. The growth rates of adult species of the oak and the Pennsylvanian ash cultivated on clay soils, and those of the Scots pine cultivated on sandy soils were studied. The results were utilized of the previously revealed correlation between the width of annual tree rings and the hydrothermal conditions of the vegetation period, with due account of different functional significance in its annual formation of spring water recharge (precipitation in the cold season), the precipitation during the vegetation period and groundwater level, as well as the limiting influence of air temperature in the spring and summer on the gain. The possibility of a sudden change of the oak growth dynamics caused by strong long-term soil and atmospheric drought during an extremely dry year (1972) is shown, when the trees of all ranks had significantly suppressed growth not only in this year but in the next 6-7 ones. This may happen due to, for example, malfunction of the cambium or the death of a large number of lateral and absorbing roots. A significant change of the growth rates of trees during long-term annual climatogenic lowering or raising of the fresh groundwater level is shown, when the lower boundary of the root systems separates from the capillary border or saturates with moisture from it, significantly changing the moisture provision of plants. The obtained results could explain the causes of the sudden change of tree growth during studies of tree rings.
