Excessive loss of water through transpiration leads to wilting. In general, there are three types of wilting as follows,
a. Incipient wilting: The water content of plant cells decreases but the symptoms are not visible.
b. Temporary wilting: On hot summer days, the freshness of herbaceous plants reduces turgor pressure in the daytime and regains it at night.
c. Permanent wilting: The absorption of water virtually ceases because the plant cell does not get water from any source and the plant cell passes into a state of permanent wilting.
