Which of the following substance is used for the degreening process of removing green colour (Chlorophyll) from the skin of fruit after harvest?
Liquid Nitrogen
Cytokinins
Ethylene gas
Auxin
Sodium salts
- Option 1: Liquid Nitrogen
Used mainly for freezing, not for removing chlorophyll.
- Option 2: Cytokinins
Plant hormones that promote cell division, not used for degreening.
- Option 3: Ethylene gas
Correct Answer. Ethylene is a natural plant hormone used widely to remove green colour (chlorophyll) from fruit skin. It helps ripening and degreening after harvest.
- Option 4: Auxin
Another plant hormone, but it regulates growth and development, not degreening.
- Option 5: Sodium salts
Not used for removing chlorophyll or degreening post-harvest.
