Other claims from this paper (13)
- Intervention effect Lowering the auxin-to-cytokinin ratio induced roots in bean callus.
- Intervention effect Lowering the auxin-to-cytokinin ratio induced vascular nodules in bean callus.
- Intervention effect Abscisic acid above I muM inhibited both differentiation types in bean callus.
- Intervention effect Abscisic acid inhibited initiation of differentiation but not later development.
- Intervention effect Gibberellic acid did not alter abscisic-acid inhibition of differentiation.
- Intervention effect Gibberellic acid alone stimulated tissue differentiation.
- Intervention effect At 30 muM GA, cell differentiation was unaffected.
- Intervention effect At 45 muM GA, cell differentiation was inhibited.
- Intervention effect GA at both concentrations delayed onset of cell differentiation.
- Association PAL activity correlated closely with the amount of cell differentiation.
- Intervention effect Abscisic acid abolished the normal rise and decline in PAL activity.
- Intervention effect Abscisic acid abolished the normal rise and decline in betaI leads to 3 glucan synthetase activity.
- Intervention effect Gibberellic acid did not affect betaI leads to 3 glucan synthetase activity.
