Endogenous: Plant hormones are endogenous substances produced by the plant’s own metabolism, also called endogenous hormones.
Mobility: Plant hormones are mobile and can be transferred to other parts of the plant after production to exert their regulatory effects. The speed and manner in which different plant hormones move vary depending on their species and the characteristics of the plant organ.
Regulatory: Phytohormones have regulatory effects and control the growth and development of plants by regulating their own concentration. Phytohormones can regulate plants through positive and negative feedback mechanisms. For example, high concentrations of auxin inhibit the growth of lateral buds, while low concentrations of auxin promote the growth of terminal buds.
Significant effect: Although the content of plant hormones in plants is very low, usually measured in nanograms and micrograms, they can significantly increase their effectiveness.
