Senescence is the natural aging process at the cellular level or range of phenomena associated with this process. The objective of this review was to show the involvement of substances that may be related to senescence in plants, such as polyamines, peroxidase and proteins. These substances were related with the terminal stages of development of various plant organs (leaves, flowers, roots).

Keywords: Flowers, putrescine, spermidine, spermine, reactive oxygen species
