e0“Field-dried shoots were viable: following recovery period, they had increased in length, shifted in hue, and displayed positive net photosynthesis, however none of these measures of metabolic activity equaled those of the controls.”

Other claims from this paper (13)
- Observation Field-dried shoots remained viable and elongated during recovery, but did not attain control activity.
- Observation Field-dried shoots shifted hue after recovery but did not match controls.
- Observation Saturated shoots had moisture content of 1296.4% by weight.
- Intervention effect IRGA caused about 40% moisture loss from initially moist shoots.
- Intervention effect IRGA did not significantly decrease net photosynthesis at the tested moisture range.
- Observation Control shoot moisture declined about 40% during IRGA and then gradually in recovery.
- Observation Control shoot net carbon gain declined over the study.
- Intervention effect Dried shoot moisture content fell an order of magnitude across treatments.
- Observation Dried shoot moisture returned near control levels after recovery.
- Intervention effect Drying reduced net photosynthesis to zero.
- Observation Net photosynthesis did not resume after rehydration.
- Mechanism The authors suggest field drying is less severe or prolonged than laboratory drying.
- Mechanism The authors suggest colony form shields inner shoots from severe exposure.
