The example of stomata closing type anti-transpirant in leaves is- (RJ ACF Ranger )

✅Explanation: Phenyl Mercuric acetate (PMA) is a stomata closing type anti-transpirant. It acts by disrupting the physiological processes that regulate stomatal opening and closing, leading to reduced water loss through transpiration.

📌 Other Options Explanations:

• Anti -transparent:
• Materials are applied to plant surface to reduce transpiration from the plant.
• Anti -transparent reducephotosynthesis.
• Hence, their use should be limited to save the crop from death under severe moisture stress. • Theyhavesome practical use in nurseries and horticultural crops.

🛑 Anti-transparents are mainly four types:
-Stomata closing type: "
• They reduce water loss through closing stomata.
• E.g. Phenyl mercuric acetate (PMA @104), Atrazine and C./2 is also an effective anti-transpirant.

✏️Film forming:
• Checks transpiration loss due toformation of thin film whichact as physical barrier.
• E.g.Mobileaf, hexadecanol, silicone, oils, waxes.

✏️Reflectingtype:
• These chemicals reflect the radiation and reduce leaf
temperature.
• Application of kaolin @ 5% reduces transpiration losses.

✏️Growth retardants:
• These chemicalsreduce shootgrowth and increase root
growth and thus enable the plants to resist drought.
• They also inducesstomata closing e.g. Cycocel (CCC).
