It is controlled by the phytohormones ABS i.e., abscisic acid.

The deciduous means falling off at maturity. This term is used in order to refer to plants that loss their leaves seasonally.
Most commonly plants loss their leaves during autumn and springs seasons. The plants become able to withstand severe cold and hot conditions.
It is controlled by the phytohormone abscisic acid. It forms a demacation layer, which finally check the contact with plan body.
The ripe fruits are also detach by this mechanism. Thank

In deciduous trees, losing leaves in the fall helps the tree store energy and resources for the dormant season, which will help it grow again in the spring by minimizing water loss and protecting it from freezing temperatures.
