Other claims from this paper (13)
- Observation In drought tolerant intensive wheat varieties, ear photosynthesis accounts for more than 60% of grain formation and protein synthesis.
- Intervention effect Under strong drought, tolerant wheat genotypes accumulate 35-70% of their protein content relative to normal water supply.
- Mechanism The authors interpret C4-cycle enzymes in C3 plants as playing a role in adaptation to stress.
- Observation High-yielding wheat genotypes tolerant to water stress have high activity of C4-cycle enzymes in leaves and ear elements.
- Intervention effect Under water stress, C4-cycle enzymes are activated in wheat.
- Observation High-productive wheat genotypes differ in the intensity of CO2 assimilation.
- Observation High-productive wheat genotypes differ in the rate of photorespiration.
- Observation The ratio of true photosynthesis to photorespiration is close to 3:1 in leaves and ear elements of wheat genotypes.
- Association The ratio of photosynthesis to photorespiration increases in intensive wheat genotypes.
- Association Intensity of true photosynthesis and photorespiration increase in parallel during leaf ontogeny in wheat.
- Recommendation The authors consider an attempt to reduce photorespiration to raise productivity inconsistent.
- Intervention effect With increasing drought or tolerance, photorespiration rate decreased to a large degree in ear elements of wheat.
- Observation A series of wheat genotypes with high primary and photosynthetic CO2 metabolism activities under water stress was identified.
