%X We studied the response of Eucalyptus microtheca to drought in a  greenhouse experiment. As a result of the drought the growth of the  seedlings decreased and allocation patterns changed so that allocation  to the roots increased. However, changes in photosynthesis and stomatal  conductance under drought were rather modest. We showed, using  chlorophyll fluorescence and measurements of photosynthesis under high  CO<sub>2</sub> that the biochemical capacity of photosynthesis increased  under drought. The results suggest that changes in root/shoot ratio are  the primary reactions that initiate a series of compensatory reactions  that mitigate the effects of drought in Eucalyptus microtheca.
