Other claims from this paper (8)
- Observation Across tobacco leaves, dark respiration stayed at 6-7% of net photosynthesis from 50 to 90 days.
- Observation In younger tobacco plants, dark respiration reached 18% of net photosynthesis.
- Observation Nine tobacco leaves had photosynthetic histories represented by one relation with developmental time.
- Observation Peak tobacco leaf net photosynthesis occurred near 37% final area, alongside peak leaf expansion rate.
- Observation Peak tobacco leaf photosynthesis lasted only 3-5 days.
- Observation Tobacco leaf photosynthesis fell below one-third of its peak by full expansion.
- Observation After 37% final area, tobacco leaf nitrogen content followed a common developmental pattern.
- Association Tobacco leaf photosynthesis, nitrogen content and ontogeny were directly related after peak photosynthesis.
