Which one of the following phytohormones is produced under water-deficit and plays an important role in tolerance against drought?
Show Hint
Remember that abscisic acid is the primary stress hormone in plants, especially during drought.
Updated On: Jun 18, 2025
- Abscisic acid
- Cytokinin
- Ethylene
- Gibberellin
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Abscisic acid is a plant hormone that is produced in response to water stress or drought conditions. It helps the plant adapt by promoting stomatal closure to reduce water loss and by triggering other stress responses.
