Other claims from this paper (9)
- Observation Under frequent irrigation, cowpea and sugarbeet had almost identical carbon gain and water-loss rates.
- Observation With irrigation withheld, sugarbeet adjusted osmotically by 0.8 kJ kg −1 and reached −2.6 kJ kg −1 minimum leaf water potential.
- Observation Sugarbeet reached a daytime minimum leaf water potential of −2.6 kJ kg −1.
- Observation Cowpea adjusted osmotically by half as much as sugarbeet.
- Mechanism Cowpea maintained higher water potential of −1.2 kJ kg −1 by stomatal closure.
- Association At a given water potential, cowpea water-loss rates were much smaller.
- Observation Sugarbeet water potential fell much more rapidly.
- Observation Carbon gain rates were similar in cowpea and sugarbeet.
- Observation Osmotic adjustment showed little or no carbon gain advantage over stomatal closure.
