Plants show temporary and permanent wilting. Differentiate between the two. Do any of them indicate the water status of the soil?
Ans.
- Temporary wilting is only the temporary change causing a turgidity loss while permanent wilting is a permanent, irreversible loss in turgidity in cells.
- The process of temporary wilting only occurs when the rate of water supply is lower than the rate of transpiration; however, permanent wilting occurs when the difference is even lower than the critical level.
- Temporary wilting is reversible and can be taken care of as soon as there is a regular supply of water, but permanent wilting cannot be reversed and will lead to the plant death.
- Temporary wilting is a phase after which the plant and resume normal functioning, but that is not the case with permanent wilting.
