Other claims from this paper (19)
- Observation RF/IRR water-potential, osmotic-potential and relative-water-content ratios differed significantly among genotypes at 50–63 days.
- Observation Water-potential ratios were maximal at 63 DAP for all genotypes.
- Observation Relative-water-content ratios were maximal at 70 DAP for all genotypes.
- Observation Comet's maximum osmotic-potential ratio was 1.25 at 56 DAP.
- Observation OK‐FH15's maximum osmotic-potential ratio was 1.32 at 63 DAP.
- Observation Florunner's maximum osmotic-potential ratio was 1.18 at 70 DAP.
- Method / resource A biphasic cubic polynomial best fitted inverse water potential versus relative water content for all genotypes.
- Association As relative water content declined, Comet water potential tended to decrease faster than the other genotypes.
- Observation Estimated osmotic-potential changes were highest for Comet.
- Observation Estimated osmotic-potential changes were lowest for Florunner.
- Observation Estimated osmotic-potential changes were intermediate for OK‐FH15.
- Observation Maximum apoplastic water fraction at high turgor was 7.1 for Florunner.
- Observation Maximum apoplastic water fraction at high turgor was 12.1 for OK‐FH15.
- Observation Maximum apoplastic water fraction at high turgor was 25.2% for Comet.
- Observation Florunner apoplastic water fraction declined to zero at 0.16 MPa turgor.
- Association OK‐FH15 apoplastic water fraction decreased with turgor to the origin.
- Observation Comet had greater apoplastic water fraction at low turgor and uniquely retained appreciable fraction at zero turgor.
- Observation Apoplastic water fraction varies among peanuts and may be genotype specific.
- Observation Rainfed Comet had significantly higher yield, grade and dollar value than Florunner or OK‐FH15.
