Overview

A general advanced course for all master's students in the department. It deals with everything related to plant hormones: an introduction to the natural ones, growth-stimulating hormones (auxins, gibberellins, cytokinins), hormones that control the end stages of growth (ethylene and abscisic acid), the molecular structure of plant hormones and How to biologically manufacture hormonal substances, industrial types (artificial growth regulators) and their composition, the physiological effects of hormonal substances from germination to aging, the role of growth regulators and hormones in differentiation, the role of plant hormones in light responses such as flowering, the relationship of phytochrome to flowering and the vital rhythm of plants, the mechanism of control of plant hormones on the activity of gene expression and vice versa, the relationship of plant hormones to genetic activity and response to environmental and cellular signals, and finally the commercial uses of growth regulators in the agricultural field.

Intended learning outcomes

Successfully completing the course, the student will be able to:

1.Distinguish in detail between types of natural plant hormones and synthetic growth regulators

2. Explain the types of natural hormonal substances and synthetic growth regulators and their functions

3. Distinguish between the functions of different hormones and industrial growth regulators and their uses for scientific, research and commercial purposes

4. Determine the stages of growth and development of plants and their relationship to the types of plant hormones in terms of their physiological effect

5. Explain how hormones are employed to deal with horticultural crops in the post-exudative stage, as well as the relationship of plant hormones to genetic activity and response to environmental and cellular signals.
