Other claims from this paper (19)
- Intervention effect Under mild depletion, relative water content did not differ significantly from well-watered seedlings in either line.
- Intervention effect NE#19 increased stomatal resistance under mild depletion.
- Intervention effect NE#19 reduced transpiration under mild depletion.
- Intervention effect NE#19 tended toward lower intercellular CO2 under mild depletion.
- Intervention effect NE#19 tended toward elevated net photosynthesis under mild depletion.
- Intervention effect NE#19 stem and root mass and specific leaf mass rose under mild depletion.
- Intervention effect NE#19 leaf area per root dry mass declined under mild depletion.
- Intervention effect NE#5 showed no analogous gas exchange or growth changes under mild depletion.
- Intervention effect Under mild depletion, NE#19 carotenoid and ascorbic acid contents increased.
- Intervention effect Under mild depletion, NE#5 peroxidase activity increased.
- Intervention effect Rewatering lowered tocopherols and malondialdehyde in both lines.
- Intervention effect Rewatering reduced ascorbic acid while carotenoids stayed high in NE#19.
- Intervention effect NE#5 peroxidase activity increased after rewatering.
- Intervention effect NE#5 Fv/Fm was higher under both mild depletion and rewatering than well-watered conditions, unlike NE#19.
- Intervention effect Severe depletion reduced relative water content, though NE#19 retained 11% more than NE#5.
- Intervention effect Severe depletion sharply reduced leaf, stem and root growth and specific leaf mass in both lines.
- Intervention effect Under severe depletion NE#19 exceeded well-watered plants in LA/RDM and R/S ratio.
- Intervention effect Severely dehydrated leaves had tocopherol levels twofold in NE#5 and threefold in NE#19 relative to well-watered plants.
- Observation After rehydration NE#5 recovered better and was judged more tolerant of severe water deficit than NE#19.
