प्रश्न
Explain the term:
Cuticular transpiration
Advertisements
उत्तर
- Cuticular transpiration is the loss of water vapor from the surface of leaves through the cuticle, a waxy layer that covers the epidermis.
- It accounts for a small portion of total transpiration (usually around 5-10%).
- The cuticle is meant to prevent water loss, but some water still escapes through it.
- It occurs more when the cuticle is thin or damaged, or under high humidity and temperature.
- This type of transpiration is non-stomatal, meaning it doesn’t involve stomata.
- It helps regulate water balance but is less efficient compared to stomatal transpiration.
