Hypothesis
How does varying nitrogen fertilization affect the synthesis of primary and secondary metabolites in Kacip Fatimah?
Conclusion
High nitrogen fertilization reduces the production of total flavonoids and phenolics in Kacip Fatimah.
Supporting Evidence
- Nitrogen levels significantly impacted the production of total phenolics and flavonoids.
- Higher nitrogen levels led to decreased production of total non-structural carbohydrates.
- The increase in total flavonoids and phenolics was correlated with enhanced phenylalanine lyase activity.
Takeaway
Giving plants too much nitrogen can make them produce less of the good stuff that helps them stay healthy and fight diseases.
Methodology
A split plot experiment with three varieties of Kacip Fatimah was conducted, applying four levels of nitrogen fertilization and measuring various metabolites.
Potential Biases
Potential bias in results due to environmental control in a greenhouse setting.
Limitations
The study focused only on three varieties and did not explore the long-term effects of nitrogen fertilization.
