Etylenpåverkad

Etylenpåverkad is a Swedish term that describes the physiological effects on plants caused by exposure to ethylene gas. Ethylene is a natural plant hormone that plays a crucial role in various aspects of plant development, including fruit ripening, senescence (aging), and abscission (leaf and flower drop). However, at elevated concentrations, ethylene can lead to abnormal growth and development.

Symptoms of ethylene influence in plants can vary depending on the plant species and the level of exposure. Common signs include epinasty, which is the downward bending of leaves and stems. This occurs because ethylene promotes cell elongation on the upper side of plant organs. Other effects can include premature yellowing and dropping of leaves, accelerated flowering and fruiting, and in some cases, stunted growth. The characteristic smell of ripening fruit is due to ethylene production.

While ethylene is naturally produced by plants, external sources can also lead to excessive exposure. These sources can include combustion processes, industrial emissions, and even other decaying organic matter. In agricultural settings, understanding ethylene's role is vital for post-harvest management, as it can significantly impact the shelf life and quality of fruits and vegetables. Techniques are employed to control ethylene levels in storage and transport to prevent premature ripening or spoilage.
