Why do leaves fall off? Why are the leaves so smooth after falling off?
◆ The reason is that some cells (originally calcium pectin, soluble pectin and pectin acid) at or near the base of petiole are produced due to changes in cell or biochemical properties.
◆ The separation zone includes: separation layer and protective layer: cells divide to produce a group of small thin-walled cells. For the separation layer, the cell wall gels and the cells become free. Due to the weak supporting force, combined with the gravity of the leaves and the shaking of the wind, the leaves fall off from the separation layer. Then several layers of cells below the abscission layer are embolized to form a protective layer on the cross section to avoid water loss and invasion of pests and diseases.
The significance of defoliation: it is an adaptation of plants to reduce transpiration, maintain water in the body and spend the cold and dry season. This habit is formed in the long-term evolution of plants.
Mechanism of defoliation: defoliation can reduce transpiration and enable plants to spend cold and dry seasons. This habit is formed in the long-term evolution of plants. Short sunshine accelerates the formation of abscission layer, and abscisic acid and ethylene increase, which can accelerate leaf abscission.
