Abstract
The control of senescence has economic importance due to its effects on parameters such as herbal product quality and shelflife. This study is on the control of induced senescence in Triticum aestivum L. `Gu?n-91' plants with silver nitrate (AgNO3) treatments. It was observed that some changes that occurred with dark and indole-1-acetic acid (IAA) treatments could be reduced with AgNO3treatments. After dark-induced senescence, it was observed in plants that seedling length, relative water content (RWC), chlorophyll,ß-carotene, xanthophylls, total antioxidant capacity, soluble phenol, total soluble protein, catalase (CAT), total superoxide dismutase(SOD), copper-zinc superoxide dismutase (Cu/Zn-SOD) activities, and expression of genes encoding these enzymes declined. AfterIAA treatments, seedling length, RWC, chlorophyll, ß-carotene, xanthophylls, total antioxidant capacity, soluble phenolics, and solubleprotein levels declined, whereas activities of CAT, total SOD, and Cu/Zn-SOD enzymes and expression of Cu/Zn-SOD and CAT genesincreased. AgNO3 (200 mg L-1 ) applied by spraying onto leaves led to an increase in seedling length, RWC, chlorophyll, ß-carotene, xanthophylls, total antioxidant capacity, soluble phenolics, soluble protein levels, and expression of Cu/Zn-SOD, CAT genes, CAT, SOD,and Cu/Zn-SOD enzyme activities compared to controls. Findings obtained from this study showed that the senescence process was related to changes in the levels of antioxidant compounds and enzymes. It was defined that the role of silver ions in slowing senescence was related to antioxidant defense capacity.
