PLANT GROWTH REGULATORS:
Plants do require the essentials like water, light, oxygen, minerals, and other nutrients for growth and development. But along with these the plants also require some other certain compounds to regulate themselves and also to control their development and growth. They are known as PLANT GROWTH REGULATORS also PLANT GROWTH HORMONES. They are compounds that help plants to grow and develop well. These are basically synthetic or biological compounds and are used in abundance in various plants to shorten the internodes and create a denser, tighter, and smaller plant.
Plant Growth Regulators compounds are basically synthesized in the laboratories or also produced in the plants. They modify the physiological process such as the development, growth, movement, and condition of the plants.

TYPES OF PLANT GROWTH REGULATORS:
The plant growth regulators are of 2 types. They are:
- Plant growth promoters
- Plant growth inhibitors.
1. Plant Growth Promoters:
It includes Auxins, Gibberellins, and Cytokines. Auxins are discovered in a lab. It is one of the most important plant hormones whereas Gibberellins are an extensive chemicals family based on the ent-gibberellance structure. Cytokines are produced in the area where cell division happens.
Functions of auxins-
- Facilitate flowering in plants
- Used in the process of plant propagation etc.
The function of Gibberellins-
- Delay senescence in fruits.
- Involve in leaf expansion etc.
The function of Cytokines-
- Break bud and seed dormancy.
- Promotes the growth of the bud etc.
2. Plant Growth Inhibitors:
Abscisic Acid and Ethylene are always grouped together. It was initially known as doormats when it was discovered in the 1960s. The growth of the inhibitor is synthesized within the stem, leaves, fruits, and seeds.
Ethylene is something that can be grouped in Plant Growth Promoters as well as in Plant Growth Inhibitors.
The Plant Growth Regulators give a boost to the plant to grow fast and in a healthy way.
TYPES OF PLANT GROWTH:
There are various types of plant growth some of them are–
1. Primary and Secondary Growth:
In Primary Growth the cells presented at the roots and the shoots of the plant divide mitotically and increase the length of the plant’s body.
And in Secondary Growth, the plant’s body is increased in a diameter way.
2. Unlimited Growth:
In this stage, the plant grows completely from the germination stage to the death of the plant.
3. Limited Growth:
At this point, the plant parts stop growing because it attains a certain size of the height.
4. Vegetative Growth:
At this stage what happens is the production of the parts like stem, leaves, and branches are taken place. Only flowers are left
5. Reproductive Growth:
At this growth stage, Flowering starts to occur.

FACTORS AFFECTING PLANT GROWTH:
There are majorly 4 factors that affect the growth of the plants. They are:
Plants are autotrophs i.e. they produce their own food using light, water, carbon dioxide, and other chemicals. Limited amount of light or absence of it can affect the growth of the plant adversely. The quality, intensity, duration of the light influence the movement of stomata, chlorophyll synthesis, photosynthesis, etc.
Plants need water to survive. About 90% of the plant’s body comprises of water. Plants tend to die without water. The soil absorbs the water presented in it and transports the nutrients along with it. Just like humans water keeps the plant hydrated.
The growth of the plants is also getting influence by the temperature. The higher the temperature the high is the speed of the growth of the plant but this does not mean that the temperature should be always high that can damage the plant.
Plants require proper nutrition to grow properly and produce goods that are full of nutrition itself. So for the growth and development of plants, nutrients are the basic and the most important thing. This is something that is to be provided to the plants from outside. As the agriculture process carries out in abundance the soil it is not having enough nutrition to grow a healthy crop/ plant thus the additional nutrition is given to the plant to grow. These micronutrients include iron, copper, sulfate, etc.

PLANT GRWOTH REGULATORS CHARACTERSTICS:
The plant growth regulators include:
As we know plants require some chemical substance along with oxygen, water, sunlight. The chemical substances are also known as the Plant growth regulators.
It also gets produces inside the plants but is not sufficient always. Thus the additional need for PGR is always there because to grow better plants we need a good amount of PGR’s.
The plant growth regulators are organic molecules with several chemical compositions. They accelerate the growth of the plants.
Plant growth regulators exhibit some characteristics some of them are:
- Differentiation and elongation of the cells.
- Formation of the leaves, flowers and stems.
- Wilting of leaves.
- Ripening of fruits.
- Seed dormancy etc.
Thus this tells us that how much importance the Plant Growth Regulators hold in the life of the plants so that it can develop. Because when we are planting a plant so that they can produce goods we need and for that, we need to give extra care and supplements. Thus one should use good quality of the Plant Growth Regulators for their plants because it gives good products and results.
