Summary Introduction

To describe:

A hormone that a farmer might use and how the hormone can help increase crop output.

Introduction:

There are many plant hormones, such as, auxin, ethylene, abscisic acid, cytokinins, gibberellins, and salicylic acid. The functioning of plant under stress is maintained by plant hormone. These hormones help plant to survive under environmental stress.

Explanation of Solution

The hormone that a farmer can use to increase crop growth is auxin hormone. This hormone is found in stem tip to promote cell elongation. It acts in the darker side of the plant and allow that side to grow. There are five types of auxins that are found in the plant. It contains the indole ring in it. Inhibiting growth of lateral buds and maintaining apical dominance are other functions of auxin hormone.
