Other claims from this paper (17)
- Intervention effect NAA showed no effect on the differentiation and elongation of apple leaves in culture.
- Intervention effect High NAA concentration inhibited growth of the apple shoot apex.
- Association Length and number of apple leaves increased with BA concentration within 0.01 to 10 μM.
- Intervention effect At 10μM BA the number of differentiating leaves was three fold that of the control.
- Intervention effect At 10μM BA the length of the longest leaf was seven fold that of the control.
- Intervention effect Gibberellic acid had no effect on internode elongation of apple shoots in culture.
- Intervention effect Gibberellic acid enhanced the differentiation and elongation of apple leaves in culture.
- Association The effectiveness of GA on apple leaves became stronger with increasing concentration within 0.01 to 0.1μM.
- Intervention effect Prolonging the culture period beyond four weeks did not further enhance leaf differentiation and elongation.
- Association GA seemed to affect shoot apex growth within four weeks of culture.
- Association The effectiveness of BA on leaf differentiation and elongation was observed at higher NAA concentrations.
- Association NAA appeared antagonistic to BA in its effect on apple leaf differentiation and elongation.
- Observation No callus formed on apple shoots cultured on media with NAA, BA or GA alone.
- Observation Callus formed on apple shoots under combined BA and NAA treatment.
- Association Callus induction and growth increased with increasing concentrations of NAA and BA.
- Intervention effect Decreasing sucrose concentration inhibited leaf differentiation and elongation regardless of BA concentration.
- Mechanism Sucrose is considered a limiting factor of leaf differentiation and elongation.
