Summary
Stevioside, a plant growth regulator, enhances wheat seedling defense against environmental stress. It boosts antioxidant enzymes and protective compounds, reducing oxidative damage.
Area of Science:
- Plant Physiology
- Biochemistry
- Agricultural Science
Background:
- Stevioside is a diterpene glycoside with potential as a plant growth regulator.
- Understanding its impact on plant stress responses is crucial for agricultural applications.
- Winter wheat (Triticum aestivum) cultivar Kazanskaya 560 is a key crop facing environmental challenges.
Purpose of the Study:
- To investigate the effects of stevioside on the antioxidant and photosynthetic systems of winter wheat seedlings.
- To determine if stevioside can mitigate oxidative stress in plants.
Main Methods:
- Seedlings of winter wheat (Triticum aestivum) cultivar Kazanskaya 560 were treated with stevioside.
- Measurements included malondialdehyde formation rate, antioxidant enzyme activities (peroxidase, ascorbate peroxidase), and accumulation of proline and carotenoids.
Main Results:
- Stevioside treatment decreased malondialdehyde formation, indicating reduced lipid peroxidation.
- Activities of antioxidant enzymes, peroxidase and ascorbate peroxidase, were significantly increased.
- Accumulation of protective compounds, proline and carotenoids, was observed in treated seedlings.
Conclusions:
- Stevioside acts as a promising plant growth regulator by enhancing the antioxidant system in wheat seedlings.
- The observed integrated effects of stevioside suggest its potential to protect plants against oxidative stress induced by adverse environmental factors.
- Further research into stevioside's application in agriculture is warranted.
