Data is presented from two years of a fully replicated field trial, that investigated the effects of water stress on the water relations and growth of established trees of two species of amenity tree, Betula pendula and Platanus x hispanica and transplanted trees of Betula pendula.

[Abstract] Data is presented from two years of a fully replicated field trial, that investigated the effects of water stress on the water relations and growth of established trees of two species of amenity tree, Betula pendula and Platanus x hispanica and transplanted trees of Betula pendula. Measurements of lateral extension and increases in stem diameter were compared to measurements of leaf water potential. Reductions in the available soil water of non-irrigated treatments brought about relative changes in the water potential of both species. Reductions in growth were only concurrent when periods of growth coincided with periods of physiological stress. Transplanted trees irrigated to near field capacity showed up to a 73% reduction in lateral extension and up to a 85% smaller increase in stem diameter compared to established trees.
