Understanding Plant Growth Regulator and their Use
Creating and maintaining a garden can be pretty amazing, garden plants come in so many shapes, sizes, and colors that will bring great change to and environment. There are edible plants and then there are plants that are non-edible which means these non-edible plants are us to create a natural and pleasing effect as we see in nature.
Having some knowledge of plant growth and its function is so important, no I am not saying that you need a college degree to be successful at gardening but having some knowledge will go a long way in giving you the success that you worked so hard at and is looking forward to. In this post, however, we will be discussing plant growth regulator and how it affects a plant’s growth
So what’s all this stuff about plant growth regulator and how does it help in the growth and development of plant life? I am so happy that you asked.
What’s a plant growth regulator
Sure plants do need water, sunlight, and carbon dioxide to survive but there are other components that plant needs in order to perform their best, these components are known as plant growth regulators. Plant growth regulators are chemical compounds that are naturally produced by plants that control their rate of growth and development. Just as our hormones play a big role in the development and functioning of our bodies so do plant growth regulators. Garden plants such as orchids, lantanas, and other flowering plants produce such beautiful flower bloom that we enjoy, well without plant growth regulators we would not have these beautiful plants.
Types of plant growth regulator
Natural plant growth regulator
- Growth inhibitors
Plant growth inhibitor is a natural occurrence in plants that promotes flower production while stopping the growth of garden plants.
Gibberellins are plant hormones that are responsible and regulates the development processes such as flower development, stem elongation, germination, leaf and fruit senescence, flower development, and dormancy.
Auxins is a plant hormone that promotes stem and root growth along with stem division. Auxins are found in shoot and root tips.
Ethylene is a gaseous hormone and plays the role of encouraging fruits to ripen, but does not promote plant growth.
Plants cytokinins are a group of growth substance that encourages the division of cells in shoots and roots. These chemicals also promote axillary bud growth, chloroplast differentiation, and the delay of senescence.
Chemical or manmade growth regulator
There are also growth regulators that are manmade, these chemicals are sprayed or applied to the plant to influence the growth and the differentiation of plant organs, cells, and tissues. These growth regulators are beneficial and will contribute to the overall health of a plant just remember to read and follow the direction on the label before applying.
Growth retardants or PGRs
Plant growth retardants are a chemical growth regulator that is applied to garden plants and crops that slow cell division and control the heights of plants without negatively impacting a plant’s development.
The advantages of plant growth retardants
1. Plant growth retardants can promote a darker green with a plant’s foliage.
2. PGRs will cause plants to have less water stress.
3. PGRs may assist in helping to fight off disease.
4. It is believed to support better water absorption.
5. It can give higher profits because of a plant’s overall appearance.
The final word on plant growth regulator
Garden plants are depending on these hormones to thrive, I am aware that knowing this stuff is not entirely dependent on having success with garden plants but having this bit of information on hand will help you to better understand how plants functions. It is amazing how complex a garden plant is no matter how big or small, these components are present to ensure the proper growth of plants. The next time you take a walk or work in your garden remember what takes place in a plant’s life for you to enjoy.
