Polyamines act as plant growth regulators.
Explanation:
Polyamines are also known as PAs. These are the aliphatic nitrogenous bases with low molecular weight having more than one amino group. Polyamines are present in most of the cells and are generated due to metabolism. These are the plant growth regulators, which help to modify the growth of the plants, increase branching, remove excess fruits, increase the return bloom, terminate shoot growth, etc.
