Barium (Ba) is a nonessential element that can cause several deleterious effects in
most organisms. Elevated Ba concentrations can be toxic for plants and may affect
growth and disturbances in homeostasis. This study aimed to evaluate the Ba stress,
the plant-tolerance limits, and the detoxification strategy adopted by Cucumis sativus
L. The effect of Ba on seed's germination and vegetative development of this species
was evaluated. For germination test, different Ba concentrations were used (0, 200,
500, 1,000, and 2,000 μM). Results showed that germination was stimulated with
500 and 2,000 µM of Ba. The toxicity effect on plant development was studied by
treating the plants with increasing doses of Ba (100, 200, 300, and 500 μM) during
45 days. Shoot and root dry biomass production decreased significantly with elevated
Ba concentrations, although water content enhanced in the roots. The concentration
of Ba, 500 µM, induced high Ba accumulation in shoots and roots (9 times higher
than in the control plants). Moreover, results showed that catalase, guaiacol peroxidase, and ascorbate peroxidase activities were stimulated in the different tissues of
cucumber plants which highlight the occurring of an oxidative damage through Ba
treatments and the involvement of the plant enzymatic antioxidant defense system. [-]
