Aqueous extracts of Tithonia diversifolia (Hemsl.) A. Gray elicit oxidative stress in Amaranthus hybridus Linn.
Journal Title: Scientia Agriculturae - Year 2016, Vol 16, Issue 1
Abstract
The allelopathic potential of Tithonia diversifolia (Hemsl.) A. Gray has been established. However very little is known about how its leachates elucidate this effect in plants. We examined the induction of oxidative stress in Amaranthus hybridus Linn. by aqueous extracts of dry and fresh shoot tissues of T. diversifolia. The extent of lipid peroxidation, membrane damage/electrolyte leakage and the activities of superoxide dismutase and catalase were determined in A. hybridus treated with extracts. The results obtained showed that the application of dry shoot extract of T. diversifolia induced peroxidation of lipids in A. hybridus while treatment with fresh shoot extract of T. diversifolia had no significant effect on lipid peroxidation. Percentage electrolyte leakage was very low (< 6 %) in the test plants under both treatments. The activities of both superoxide dismutase and catalase increased in the test plants under both treatments throughout the experiment. These findings suggest that allelochemicals in T. diversifolia induced oxidative stress in A. hybridus. However, in this case, the effect of the induced stress on membrane lipids was mitigated by the high activities of both antioxidant enzymes as evident in the low percentage ion leakage observed in the test plants.
