The composition of buds, roots and young shoots

The buds in the growth phase as well as the roots have growth hormones, Phytohormones which have the virtue of crossing cell walls and increasing the production of RNA at the origin of the production of proteins.

THE Phytohormones:

THE Auxins
Comes from Greek auxin meaning to grow: it is a growth hormone which induces plant phototropism (the orientation of the plant towards light), it also promotes DNA duplication, stimulates resistance to diseases, contributes to cell regeneration and has anti-inflammatory qualities.

THE Gibberellins
Currently we know 80 different ones. They contribute to germination by lifting the dormancy of the seeds as well as to the bursting of buds through the action of vernalization (winter dormancy). They stimulate RNA synthesis and are anti-inflammatory. They cause flowering.

THE Cytokinins
They contribute, in the presence of Auxins, to cell division and growth, stimulate the creation of young shoots and the separation of chromosomes. They contribute to the production of chlorophyll.

Abscissin (Or Dormina ) ABA
It contributes to the closure of the stomata of the buds in the event of water stress or nutritional stress (anti-stress growth inhibitor, adaptogenic hormone) and participates in leaf fall, it stops the growth of the buds (vernalization) and strengthens the defenses of the buds. plants.
