Other claims from this paper (12)
- Intervention effect Ascorbate at 10 mM increased shoot formation in wheat calli.
- Intervention effect Hydrogen peroxide at 10 mM increased shoot formation in wheat calli.
- Observation The 10 mM treatments increased H2O2 levels in wheat calli, indicating mild oxidative stress.
- Intervention effect Hydrogen peroxide at 20 mM improved shoot regeneration in wheat calli.
- Intervention effect Ascorbate at 20 mM had no effect on shoot regeneration in wheat calli.
- Intervention effect Ascorbate at 40 mM had no effect on shoot regeneration in wheat calli.
- Intervention effect Hydrogen peroxide at 40 mM had no effect on shoot regeneration in wheat calli.
- Intervention effect Ascorbate at 20 mM was very harmful to wheat calli, with low survival.
- Intervention effect Ascorbate at 20 mM reduced the levels of oxo-indole-3-acetic acid glucose-ester and trans-zeatin-glucosides in wheat calli.
- Intervention effect Ascorbate at 20 mM reduced the level of isopentenyladenosine and its 9-glucoside in wheat calli.
- Intervention effect Ascorbate at 20 mM may cause a much greater decrease of polyamine levels than 20 mM H2O2 in wheat calli.
- Recommendation H2O2 seems more appropriate than ascorbate for inducing shoot formation during wheat transformation and micropropagation.
