Other claims from this paper (11)
- Observation Mexican redbud had greater photosynthesis than eastern redbud.
- Observation Mexican redbud had greater instantaneous water use efficiency than eastern redbud.
- Mechanism Leaf thickness may explain the photosynthesis and water use efficiency differences.
- Observation The optimal temperature for photosynthetic capacity was 37 °C and unaffected by irrigation or ecotype.
- Observation Eastern redbud had more negative tissue osmotic potential at full turgor.
- Intervention effect Drought did not affect osmotic potential in either ecotype.
- Observation Eastern redbud had higher soluble carbohydrate content.
- Observation d -pinitol was the major soluble carbohydrate in both ecotypes.
- Intervention effect Water stressed plants had considerably more d -pinitol.
- Intervention effect Water stressed plants had greater total polyol content.
- Observation Both ecotypes were very tolerant of heat and drought.
