Abstract

Recent agriculture is characterized by intensive and cleaning productions, which need seeds with high quality in large quantities bonded by in vitro culture labs. Nevertheless, in vitro ex vitro transition and during acclimatization losses occur due to the death of plantlets unable to survive this abiotic stress. Reactive oxygen species production during jasmonic acid-induced changes of previous transition was demonstrated. The role of superoxide dismutase in regulation of oxidative metabolism signaling in response to environmental stress is analyzed. Pineapple plantlets treated with jasmonic acid showed higher protein biosynthesis, which can be associated with a better regulated metabolic predisposition to face this phase, when superoxide dismutase activity showed adequate control against this stress in relation to superior water-use efficiency and survival.

 

Key words: Environmental stress, water-use efficiency, survival.
