TL;DR: The role of PGRs in the physiological response to the abiotic stresses of water deficit, water excess, temperature, nutrition and mechanical perturbation is discussed along with cross-adaptation in the interactions of these stresses.
Abstract: Abiotic and biotic stresses elicit changes in normal physiology of trees. Plant growth regulators (PGR) are involved in the stress response and appear to have two roles: 1) to minimize the impact of the stress on the tree and; 2) to trigger stress resistance mechanisms. In the latter case the PGR-induced changes appear to enhance resistance to subsequent stress. This cross-adaptation to stress is important in trees.
