Abstract
The project will extend our current work on the influence of root-sourced chemical signals on stomatal behaviour and growth of plants in the field. There are three main objectives. 1) To reassess the importance of metabolism and compartmentalisation of ABA arriving in the leaf in the transpiration stream to try to determine, for example, why stomata are not closed all of the time and why leaf growth is more sensitive to soil drying than stomatal behaviour. 2) To determine the basis of variation of responsiveness of stomata and growth to ABA at different water potentials and different temperatures. 3) To extend our current model of chemical control of stomatal behaviour to incorporate information on metabolism and compartmentation and to take account of the influence of a greater range of climatic variables.
