| Goal and objectives of the project | Providing scientific data on the effects of nano ceria on the growth, development, physiology and biochemistry of Chrysanthemum and Fragaria × ananassa plantlets cultured in vitro |
| Main results | - Theoretical results: Some new scientific information is initially provided on the effects of CeO2NPs on the growth, development, nutrient absorption, and antioxidant enzyme activity of Chrysanthemum and Fragaria × ananassa plantlets cultured in vitro for research and teaching activities.
- Applied results: The project's results have high potential for application in the field of plant micropropagation |
| Novelty and actuality and scientific meaningfulness of the results | - Fragaria × ananassa: The medium supplemented with 1.0 mg/L SiO2NPs showed enhanced mineral absorption, while the medium supplemented with 1.0 – 1.5 mg/L CeO2NPs created the most favorable conditions for the activity of antioxidant enzymes. As a result, the plantlets at these concentrations also exhibited superior morphological and physical characteristics. The creative combination of SiO2NPs and CeO2NPs in RSM-based culture medium has great scientific and practical significance in Fragaria × ananassa plantlets in vitro propagation, not only maximizing plant growth but also overcoming the weakness of stems.
- Chrysanthemum: The addition of CeO2NPs under salt stress conditions based on RSM increased the free radical scavenging activities of antioxidant enzymes (SOD, CAT, APX). In this study, the maximum salt tolerance threshold of Chrysanthemum and the corresponding CeO2NPs concentration were 30 mM NaCl and 12.8 mM CeO2NPs. Under these culture conditions, the adaptability of in vitro plantlets to salt stress condition was enhanced, leading to the improvement in morphological and physiological characteristics, thereby increasing crop yield under salinity stress. |
