Other claims from this paper (9)
- Observation The highest survival rate of Viola odorata seedlings (97.78%) occurred in the untreated control group.
- Intervention effect Colchicine at 0.3% for 48 h was the most effective treatment for tetraploid induction in Viola odorata.
- Observation Tetraploid Viola odorata plants had increased stomatal size.
- Observation Tetraploid Viola odorata plants had reduced stomatal density.
- Intervention effect Compared with diploids, tetraploids had significantly higher photosynthetic pigments, total protein and PAL activity.
- Intervention effect Compared with diploids, tetraploids had significantly higher vitamin C, total phenolic and flavonoid contents.
- Intervention effect Tetraploids had enhanced activities of catalase, ascorbate peroxidase and guaiacol peroxidase compared with diploids.
- Observation Tetraploids had increased fresh and dry weight.
- Mechanism The authors suggest that higher biomass in tetraploids may contribute to the elevated biochemical and phytochemical levels.
