HORTICULTURE

Detailed explanation-1: -On a hot, dry day (or after several days with no rain or watering), transpiration causes more water to be lost than is coming in, and the water balance within the plant can get thrown off. The dehydrated collapsing cells in the leaves and stems can no longer remain erect, and the plant begins to wilt.

Detailed explanation-2: -Wilting can be caused by drought or waterlogged soil Plants wilt when roots are unable to supply sufficient moisture to the stems and leaves. Wilting for short periods of time does not harm plants. Sometimes a plant wilts on a hot day because moisture is evaporating from the leaves faster than the roots can take it up.

Detailed explanation-3: -When the soil of a plant runs too low of available water, the water chains in the xylem become thinner and thinner due to less water. Effectively, the plant is losing water faster than it is absorbing it. When this happens, the plant loses its turgidity and begins to wilt.

Detailed explanation-4: -Plants wilt due to the lack of water and moisture during hot days. The rate of transpiration increases, and the water pressure is not maintained, which does not allow water to flow from roots to the leaves. If the roots of the plant do not get enough water, the leaves tend to wilt.

Detailed explanation-5: -The reduced volume of water in the vacuole reduces the turgor pressure exerted upon the cell membrane, so it pulls away from the cell wall. This causes the cell to reduce in size and appear shrunken and wrinkled.
