Question

Define wilting. Why do some plants show wilting of their leaves at noon even in well watered soil?

Answer 1

Wilting:

Wilting is the loss of turgidity of leaves and other soft aerial parts causing drooping, folding, and rolling.

Wilting is of three types:

A) Temporary wilting:

1. It is the temporary drooping down of leaves and young shoots due to the loss of turgidity.
2. It is very well revised simply after the pace of transpiration diminishes joined by the renewal of water around root hairs.

B) Incipient wilting:

1. Partial and temporary loss of turgor in a plant that occurs in the presence of adequate soil moisture
2. It is associated with excessive water loss through transpiration.

C) Permanent wilting:

1. It is that state in the loss of turgidity of leaves when they do not regain their turgidity even when being placed in a suitable atmosphere.
2. Permanent wilting leads to the death of the plant.

Reason for the plants to show wilting at noon even in well-watered soil:

1. Such type of wilting in which a plant wilts even in the presence of enough moisture in water is called incipient wilting.
2. This occurs because of excessive loss of water by transpiration.
3. The rate of loss of water vapor in transpiration in these plants exceeds the rate of absorption of water by the roots.
4. The plants suffer a lack of water and wilt.
5. This type of wilting can be seen in Balsam plants.
