Other claims from this paper (19)
- Observation Tomba was comparatively tolerant for tuber and starch yield under nitrogen deficiency and drought.
- Observation Kiebitz was rather sensitive for tuber and starch yield under nitrogen deficiency and drought.
- Observation Other potato cultivars responded differently according to stress type.
- Intervention effect Nitrogen use efficiency generally increased under nitrogen deficiency.
- Intervention effect Water use efficiency decreased under limited water supply.
- Intervention effect Increased nitrogen supply increased water use efficiency.
- Intervention effect Leaf proline content increased under drought.
- Association Nitrogen supply affected the speed and extent of proline accumulation.
- Intervention effect Total soluble sugars increased under short term drought.
- Intervention effect Total soluble sugars fell back under long term drought, more strongly with higher nitrogen supply.
- Intervention effect Leaf water potential rapidly decreased under drought.
- Observation Significant osmotic adjustment was not detected during drought.
- Association Biochemical and physiological traits correlated too weakly with agronomic traits to be stress tolerance markers.
- Observation Cultivars differed significantly in maintaining biomass production, photosynthesis and nitrogen metabolism under reduced nitrogen supply.
- Intervention effect Nitrogen deficiency increased root to shoot ratio in some cultivars.
- Observation Protein abundance differed between sensitive and tolerant genotypes for 21 % of detected proteins.
- Observation In control and nitrogen deficient conditions, 19.5 % of proteins were differentially accumulated in the sensitive genotype.
- Observation In control and nitrogen deficient conditions, 15 % of proteins were differentially accumulated in the tolerant genotype.
- Observation Only eight of 106 differentially abundant proteins occurred in both genotypes and were mainly linked to general stress response.
