The regulator that retards the aging senescence of plant parts is Cytokinin.
- Cytokinin is a plant hormone that promotes cell division and delays aging.
- It helps in maintaining the youthfulness of plant tissues by preventing aging effects like yellowing of leaves.
- By stimulating cell division, cytokinins contribute to the overall growth and development of plants.
- This hormone plays a crucial role in various physiological processes, including delaying senescence and promoting overall plant health.

Yes, it's Option-A.
=> Cytokinin are Synthesised in region where rapid cell division occurs.
=> it helps to produce new leaves, chloroplast in leaves, lateral shoot growth and adventitious shoot formation.
=> helps overcome the apical dominance.
=> promote nutrient mobilisation which helps delay of leaf senescence.

The regulator which retards ageing senescence of plant parts isa)Cytok...
Explanation:
Cytokinin:
- Cytokinin is a plant growth hormone that plays a crucial role in retarding the ageing process in plant parts.
- It helps in delaying senescence, which is the natural process of ageing and deterioration in plants.
- Cytokinins promote cell division, leaf expansion, and overall plant growth, thereby slowing down the ageing of plant tissues.
Auxin, Gibberellin, and Abscisic Acid:
- While auxin, gibberellin, and abscisic acid are also plant hormones that regulate various growth processes in plants, they do not specifically retard ageing like cytokinin.
- Auxin is involved in promoting cell elongation and apical dominance.
- Gibberellin is responsible for stem elongation and seed germination.
- Abscisic acid is known for its role in seed dormancy and stress responses in plants.
In conclusion, among the options provided, cytokinin is the plant hormone that specifically retards ageing senescence of plant parts by promoting growth and delaying the natural ageing process.
