Study Notes
Auxins in Plants
- The main naturally occurring auxin in plants is indole-3-acetic acid (IAA).
- Auxins are primarily synthesized in the shoot apical meristem and young leaves, as well as in developing fruits.
Phytohormones and Their Functions
- Gibberellins are the phytohormones that promote the growth of internodes by facilitating cell elongation.
- Cytokinins are the phytohormones known for delaying leaf senescence, thus promoting cell division and growth.
Auxin Action
- Auxin induces the formation of roots in cut stems, aiding in the propagation of new plants.
