Abstract:
The flower is the organ with the shortest period of longevity. Petal shedding or petal abscission is a serious problem in many ornamental and commercial flower crops. Petal shedding may be regarded as the final stage of flower senescence. Senescence accomplishes through the changes that lead sooner or later to death of an organism or some part of it, while aging occurs in time without reference to death as a consequence. Petal senescence is an irreversible process and it has been the last phase of life in which, a series of normally irreversible events are initiated that lead to cellular breakdown and death. This article gives an idea about senescence, its types, causes and changes occurring during this process in the flower crops and the factor to control the abscission.
