Read the following statements regarding the physiological effects and agricultural applications of gibberellins. Identify the incorrect statement.

Options

  1. ASpraying sugarcane crop with gibberellins increases the length of the stem, thereby increasing the yield.
  2. BSpraying juvenile conifers with gibberellins delays their maturity period, thus preventing early seed producti
  3. CGibberellic acid ( GA ₃ ) is used to speed up the malting process in the brewing industry.
  4. DGibberellins cause fruits like apple to elongate and improve in shape.

Correct answer

B. Spraying juvenile conifers with gibberellins delays their maturity period, thus preventing early seed producti

Step-by-step solution

Gibberellins have several important agricultural applications. The statement in option 2 is incorrect because spraying juvenile conifers with gibberellins hastens the maturity period, thus leading to early seed production, rather than delaying it. The other statements are correct according to NCERT. Gibberellins increase the length of the stem in sugarcane, increasing yield by up to 20 tonnes per acre. GA ₃ is widely used to speed up the malting process in the brewing industry. They are also used to cause fruits li
