Etiolation on euphorbia royleana
What's Happening
Euphorbia royleana exhibits high phenolic content (up to 112.65 mg GAE/g) and flavonoid concentration (217.31 mg RE/g in reproductive tissues) providing antioxidant protection. Inadequate light reduces photosynthesis and phenolic production, causing etiolation (stretching) as plants reach for light. These compounds require bright light for synthesis.
How to Fix It
- 1
1. Provide bright light (indirect or morning sun) for 6+ hours daily
- 2
2. Rotate pots weekly for even light exposure
- 3
3. Use diluted fertilizer (half strength) only during active growth periods
How to Prevent It
Maintain proper light intensity (6+ hours bright indirect or morning sun). Avoid over-fertilization which can dilute beneficial compounds. Provide adequate stress (moderate drought, bright light) to trigger compound synthesis.
