Physiological reactions of spruce (Picea abies) on complex SO 2 ‐ and drought‐induced stress. Part 3. Responses of SO 2 ‐stressed spruces to subsequent drought‐induced stress. SO 2 ‐stressed spruces under drought‐stress showed less reduced water content, less increased osmotical potential and less restricted photosynthesis compared to spruces without preceding SO 2 ‐stress and thus seemed to be in a better physiological situation. Their ability to retain water (in cut‐off twigs) as well as their ability to withstand a quick and strong water‐loss in the needle‐tissue without cell‐damage were reduced. Reasons for the temporarily favourable effect of a pre‐going SO 2 ‐stress in surviving a drought‐stress are discussed.
