Studying the interrelationships between the various plant growth regulators is a necessary step for the understanding of the physiological and morphogenic responses in vivo and in vitro. Polyamines (PAs) occupy a particular niche amongst the plant growth regulators in that, although they share some of the features of traditional phytohormones, such as gradients of synthesis/accumulation associated with juvenility, and growth and differentiation processes (Bagni and Torrigiani 1992), other characteristics, namely order of magnitude and lack of specific receptors, differentiate them and suggest similarities with second messengers. Further research on PA-binding proteins (Tassoni et al 1998) may help to clarify this issue.

Abstract
Studying the interrelationships between the various plant growth regulators is a necessary step for the understanding of the physiological and morphogenic responses in vivo and in vitro.
