- Intervention effect At low measurement PPFD, low-irradiance grown leaves had higher photosynthesis.
- Intervention effect A low developmental R:FR reduced leaf photosynthetic capacity.
- Intervention effect At high growth irradiance and R:FR 0.7, photosynthesis fell 42 to 89% relative to R:FR 1.3.
- Intervention effect At low growth irradiance and R:FR 0.7, photosynthesis fell 21 to 24% relative to R:FR 1.3.
