Other claims from this paper (16)
- Intervention effect Short heat stress did not change net photosynthetic rate, stomatal conductance or most fluorescence parameters in either accession.
- Observation Short heat stress was accompanied by low electrolyte leakage.
- Intervention effect Heat significantly reduced photosynthetic capacity, more in AC 524 than AC 102.
- Association Relative water content below 70% sharply decreased photosynthetic rate and stomatal conductance.
- Intervention effect Drought affected fluorescence parameters, photosynthetic capacity and injury index in both accessions.
- Intervention effect Both accessions lost 42% of total fatty acids under water stress.
- Observation Galactolipid contents fell drastically.
- Observation Drought disorganized grana stacking in AC 524 thylakoids.
- Observation Mitochondrial cristae showed injury.
- Intervention effect Adding high temperature to drought did not significantly change photosynthesis and fluorescence parameters in either accession.
- Intervention effect Heat added to drought increased electrolyte leakage in AC 524.
- Intervention effect Heat added to drought did not increase electrolyte leakage in AC 102.
- Observation Combined stress increased disorganization of chloroplasts, mitochondria and plasmalemma.
- Observation Vesicles appeared in the cytoplasm.
- Observation Cytoplasm became electron transparent with strongly fewer ribosomes.
- Observation AC 102 was less affected than AC 524 in photosynthetic capacity and membrane integrity.
