Other claims from this paper (11)
- Intervention effect Salt exposure negatively affected measured rice seedling growth and biochemical parameters except chlorophyll.
- Intervention effect High salt nearly doubled chlorophyll concentrations.
- Intervention effect Gibberellic acid counteracted salt effects on shoot length, shoot dry weight, carotenoid and chlorophyll b content.
- Intervention effect Extracellular products nullified salt effects on shoot dry weight and carotenoid content.
- Intervention effect Extracellular products partially counteracted salt induced shoot length decline from 54% to 38%.
- Intervention effect Extracellular products partially counteracted salt induced total free porphyrin decline from 31 to 13%.
- Intervention effect Extracellular products reduced the salt induced increase of chlorophyll a by 35%.
- Intervention effect Extracellular products had no effect on root length and chlorophyll b under salt.
- Intervention effect Gibberellic acid increased 5-aminolevulinate dehydratase activity over unsalted control.
- Intervention effect Extracellular products increased 5-aminolevulinate dehydratase activity over unsalted control.
- Mechanism The authors propose that Scytonema hofmanni products may counteract hormone imbalance in salt stressed rice through gibberellin like regulators.
