In this article, we will discuss about the transport of auxin in plants. The auxins are synthesized in growing menistematic regions of plant from where they are transported to other plant parts. The transport of auxin in plant is predominantly polar. In stems, polar transport of auxin is basipetal i.e., it takes place from apex towards base. In roots also, [...]
The following points highlight the eight physiological effects of auxin in plants. The physiological effects are: 1. Cell Elongation 2. Apical Dominance 3. Root Initiation 4. Prevention of Abscission 5. Parthenocarpy 6. Respiration 7. Callus Formation and 8. Vascular Differentiation. Physiological Effect # 1. Cell Elongation: The primary physiological effect of auxin in plants is to stimulate the elongation of [...]
