Abstract:

The interactive effect of moisture stress and elevated CO₂ on the oxidative injury in Brassica species, B. juncea cv. RH-30 and B. campestris cv. Pusa Gold was examined. CO₂ enrichment and moisture stress treatment were done using Free Air CO₂ Enrichment (FACE) and restricted irrigation technologies. Moisture stress treatment increased the accumulation of H₂O₂ and oxyradicals. The elevated CO₂ reduced the accumulation of active oxyradicals and increased the activity of antioxidant enzymes ameliorating the drought-induced oxidative stress effects in Brassica species.

Keywords:

Brassica juncea, Brassica campestris, FACE, elevated CO₂, moisture stress, oxidative stress, antioxidant enzymes
