At a whole plant level the effects of drought is usually perceived as a decrease in growth and photosyntheticcarbon assimilation. That is why this review is focused mainly on recent information about the effects ofdrought on plant growth, water relations and photosynthesis, as well as mechanisms of adaptation. It is shownthat plants have evolved a great number of adaptive mechanisms that allow the biochemical systems to copewith increased water deficit. The literature analyzed in this review shows the complexity of tolerance to waterdeficit and supports the statements of many authors that the flexibility of cell metabolism and its fastacclimation to changes in environmental conditions is a first essential step in stress avoidance.
