    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:
    A A, B, C and D Correct Answer Incorrect Answer
    B A, B and D only Correct Answer Incorrect Answer
    C B, C and D only Correct Answer Incorrect Answer
    D B and C only Correct Answer Incorrect Answer

    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.
