Leaf separation point

Leaf separation point

The leaf separation point performs two functions:

  • provides fall shedding of leaves in autumn;
  • prevents the drying, spreading of diseases and damage to the part of the plant from which the leaf comes off.

In autumn, the change in the color of foliage of deciduous trees is associated with the decomposition of chlorophyll, which allows the appearance of other pigments contained in the leaves. Reduction of the duration of daylight hours in combination with cold nights leads to increased accumulation of sugars and slows the production of chlorophyll. This process also allows other pigments, including anthocyanins (red and purple) and carotenoids (yellow, orange and red) to appear. Another interesting fact in Star Trek Adversaries Free Points

Trees that drop leaves every year are called deciduous, and those that retain it for more than one year are called coniferous or evergreen. Falling leaves are caused by cellular changes and growth regulators that form the point of separation of the organ at the base of the petiole, or the stem of the leaf.
