Plants lose water and cells cannot maintain the symptoms of normal tension. Since plants are also losing water (such as transpiration) while absorbing water, when the water potential of the soil is lower than a certain value, the absorption and loss of this water cannot be balanced, and the lost water will be more than the absorbed water, and the plant will Wilting occurs when turgor is lost. At this time, if the loss of water is reduced, the water can reach a new balance, so the turgor pressure of the plant is restored and the wilting phenomenon disappears.
In agricultural production, this wilting phenomenon occurs when the water absorption of crops cannot compensate for the water loss. For example, under the scorching summer sun, the young parts of dicotyledonous plants sag. Young leaves of grasses curl into tubes. If wilting occurs for a short period of time, it will not affect the growth of crops. If wilting occurs for a long time, photosynthesis will be weakened, growth and development will be blocked, and it will cause plant death in severe cases.
