Cytokinin helps in delay of leaf senescene by

Options

A. Increasing more water absorption by root-
B. Increasing rate of translocation of organic solutes
C. Promoting nutrients mobilization
D. Formation of adventitious buds

Answer

**Step-by-Step Solution:**

1. **Understanding Leaf Senescence**:
- Leaf senescence refers to the aging process of leaves, where they undergo physiological and biochemical changes that lead to their eventual death. During this phase, the plant reallocates nutrients from older leaves to younger parts for growth.

2. **Role of Cytokinins**:
- Cytokinins are a class of plant hormones that play a crucial role in promoting cell division and growth. They are known to delay the aging process in plants.

3. **Mechanism of Action**:
- Cytokinins help in delaying leaf senescence by promoting nutrient mobilization. This means that they facilitate the transfer of essential nutrients from aging leaves to younger, growing tissues.

4. **Nutrient Mobilization**:
- By enhancing nutrient mobilization, cytokinins ensure that the nutrients present in the senescing leaves are not lost but instead are redirected to support the growth of younger parts of the plant.

5. **Conclusion**:
- Therefore, cytokinins effectively delay leaf senescence by promoting the mobilization of nutrients, which helps maintain the health and vitality of the plant.
