Transpiration of birch seedlings in the field is largely controlled by the amount of available water in the soil. This is in contrast with the situation found in CO 2 exchange, where distinct interaction between temperature and drought was observed in our previous studies. The present study indicates that no similar relationships exist as far as transpiration is concerned, and in agreement with our previous preliminary studies, separate control mechanisms thus seem to affect transpiration on the one hand and photosynthesis on the other under natural conditions.
