Abstract
The effect of water stress on growth and essential oil metabolism wasstudied in two species of aromatic grasses under induced water stressconditions. Cultivars of Cymbopogon martinii andC. winterianus differed considerably in their response towater stress. Plant growth, oil yield and water potential decreased whileproline accumulation and oil biogenesis increased in the different genotypesunder water stress. Water stress induced a wide variation in essential oilcomposition, protein content and in activities of PEP carboxylase and nitratereductase in the different genotypes in terms of increase, decrease or nochange. The physiological and biochemical basis of drought tolerance inC. martinii has been elucidated on the basis of growth andmetabolic responses.
