lõhustumine

Lõhustumine is a physiological process that occurs in living organisms, particularly in plants and flowers. It refers to the phenomenon of wilting, drooping, or weakening of a plant's tissues due to the loss of turgor pressure. Turgor pressure is the force exerted by water within the plant cells against the cell walls, and it is responsible for maintaining the plant's structure and rigidity.

During lõhustumine, the plant's cells lose their ability to maintain turgor pressure, and the cells begin to lose water through a process called transpiration. This results in a decrease in the plant's water potential, leading to a loss of rigidity and a drooping of the leaves and stems.

Lõhustumine can be caused by various factors, including lack of water, high temperatures, salinity, and injury to the plant. Plants that experience lõhustumine must have enough water to recover and regain their turgor pressure. Without sufficient water, the plant may die.

In some cases, lõhustumine can be reversible by providing the plant with enough water. However, if the plant is severely dehydrated or injured, lõhustumine can be irreversible. Some plants, such as cucumber and apricot, are more prone to lõhustumine than others due to their thin cell walls and high transpiration rates.

Proper irrigation and watering management can help prevent lõhustumine in plants. This includes monitoring soil moisture levels and providing plants with enough water to meet their needs, especially in hot and dry weather conditions.
