Perishable vegetables can be maintained fresh for a longer period by spraying them with a solution of
- A ABA
- B cytokinin
- C ethephon
- D phenylmerucric acetate
Answer & Solution
Correct Answer
(B) cytokinin
Step-by-step Solution
Detailed explanation
(B) cytokinin,
Perishable vegetables can be maintained fresh for a longer period by spraying them with a solution of cytokinin. Cytokinins delay senescence and help in extending the shelf life of vegetable by reducing the rate of aging.
