Plant Growth Regulators, Sex Expression, Part
- Sex Expression Regulation in Bitter Gourd (Momordica charantia):
- Plant growth regulators strongly shift the staminate-to-pistillate sex ratio in monoecious cucurbits.
- Cycocel (CCC / Chlormequat chloride) applied at $50 - 200\text{ ppm}$ promotes staminate (male) flower induction.
- In contrast, ethrel ($100 - 200\text{ ppm}$) or silver nitrate stimulates pistillate (female) flower development.
- Correct Option: Option 2 (50-200 ppm).
