Design & Construction

In this unit, you will learn about common growth regulators used in greenhouse crops production. You will learn about the appropriate uses of each growth regulator, and how to calculate concentrations and parts-per-million for growth regulator application.

  1. Introduction

  2. Non-Chemical Growth Control
    • Water stress
    • Nutritional stress
    • Light
    • Root restriction
    • Pinching
    • Thigmotropic responses
    • DIF and DROP

  3. Chemical Growth Control

    • Benzyladenine + Gibberellin Combinations

  5. Application of Growth Retardants
    • Environmental conditions
    • Crop
    • Stage of crop
    • Concentration
    • Method of application
