Identify the "Growth Retardants" used in crop plants

A. Maleic Hydrazide

B. Chloromequat Chloride

C. Paclobutrazole

D. Triiodobenzoic acid

Choose the correct answer from the options given below:

Solution

Maleic Hydrazide (A): It is a growth retardant used in crop plants to inhibit cell division, thus controlling the growth. Chloromequat Chloride (B): This is another growth retardant that is commonly used to regulate the height of certain crops. Paclobutrazole (C): It is a triazole plant growth regulator that inhibits gibberellin biosynthesis, resulting in shorter and more compact plant growth. Triiodobenzoic acid (D): This is a chemical compound that has been studied for its effects on plant growth and development. It is an inhibitor of polar auxin transport and more commonly known as TIBA.
