Other claims from this paper (12)
- Intervention effect Increased salinity decreased the number of fertile florets in rice.
- Intervention effect Increased salinity decreased pollen viability in rice.
- Intervention effect Seed set was reduced by 38% in female plants grown in 10 mol m-3 Na.
- Intervention effect Seed set was reduced by 72% in female plants grown in 25 mol m-3 Na.
- Association Salinity effects on female parents dominated those on male pollinator parents in rice crosses.
- Observation K concentration showed a leaf-to-leaf gradient opposite to that of Na and Cl in rice.
- Observation K concentration was highest in the flag leaf, where Na and Cl were lowest.
- Intervention effect Saline conditions increased Na and Cl concentrations in rice pollen grains and stigmas.
- Intervention effect Saline conditions decreased K concentration in rice pollen grains and stigmas.
- Association Na and Cl concentrations in rice pollen were correlated with pollen staining and germination in vitro.
- Mechanism Na and Cl per se were suggested to be responsible for poor pollen viability in rice.
- Observation Change in ionic concentrations was larger in rice pollen and stigmas than in younger leaves.
