Which of the following Antitranspirents is the stomatal closure type?

Which of the following Antitranspirents is the stomatal closure type? Correct Answer PMA

The correct answer is PMA

  • Antitranspirents are the material or chemical which decreases water loss from the plant leaves by reducing the size and number of stomata.
  • Stomatal closure type of antitranspirents induce stomatal closing or decrease size and number of stomata which subsequently reduce the photosynthesis.
  • Antitranspirents that are used for stomatal closing are (Phenyl mercuric acetate )PMA, Abscisic acid, and high co2 concentration. 
  • PMA is a widely used chemical for stomatal closure.
  • It has the ability to closure the stomata.
  • This chemical also inhibits phosphorylation and hence damages the foliage by blocking photosynthesis.
