The hormone responsible for nutrient mobilization which helps in the delay of leaf senescence is
Options
- Aauxin.
- Bgibberellin.
- Ccytokinin
- Dethylene.
Correct answer
C. cytokinin
Step-by-step solution
Natural cytokinins are synthesised in regions where rapid cell division occurs, for example, root apices, developing shoot buds, young fruits etc. It helps to produce new leaves, chloroplasts in leaves, lateral shoot growth and adventitious shoot formation. Cytokinins help overcome the apical dominance. They promote nutrient mobilisation which helps in the delay of leaf senescence.
