ABSTRACT:
A natural substance that acts to control plant activities are Plant growth regulators and often called phytohormones to regulate growth, development and responses to stimuli. Which includes hormones and non-nutrient chemicals not found naturally in plants that when applied in plants, influence their growth and development. Changes in phytohormone levels result in gene activation shifts. This paper accomplishes the review article on chemistry of the novel plant growth regulators according to their medications, and has been discussed according to the types of plant growth regulators.

INTRODUCTION:
Plant growth regulators/plant hormones are chemicals which are related to the growth of the plant are known as 'plant growth substances'. Low concentrated signal molecules are produced in the plant were the hormone cells regulate the cells locally and moved to other locations^1,2. Two types of plant growth regulators are used in the nature named as Natural and Synthetic types:

Natural PGH= generated by the plant
Synthetic PGH= Development done by the humans

Both the groups regulate:
· Cell division
· Cell differential
· Root and shoot growth
· Plant aging

The following are the classification of Plant Growth Regulators:
· Auxins
· Gibberilins
· Cytokinenins
· Abscisic acid
· Ethylene

The following are the chemistry of the classified plant growth regulators:

ANTI-AUXINS:

CYTOKININS:

DEFOLIANTS:

ETHYLENE INHIBITORS and ETHYLENE RELEASERS; GAMETOCIDES and GIBBERELLINS:

GROWTH INHIBITORS:
