Other claims from this paper (6)
- Association In birch, mature shoots had increased peroxidase and polyphenol oxidase activity in shoot apices and stems compared with rejuvenated shoots.
- Intervention effect In birch, prolonged subculture time significantly affected peroxidase and polyphenol oxidase activity in shoot apices.
- Intervention effect In birch, prolonged subculture time did not affect shoot maturation.
- Intervention effect In birch, high sucrose concentration significantly increased total phenolic concentration in leaves.
- Intervention effect In birch, high sucrose concentration significantly increased polyphenol oxidase activity in all plant parts.
- Intervention effect High sucrose concentration was stated to enhance shoot maturation and recalcitrance of birch in vitro.
