Question

Spraying sugarcane crop with which of the following plant growth regulators, increases the length of stem, thus, increasing the yield?

Options

• Cytokinin

• Abscisic acid

• Auxin

• Gibberellin

Answer 1

Gibberellin

Explanation:

Plant hormones called gibberellins stimulate cell division and elongation, which leads to stem elongation. Gibberellin spraying sugarcane crops can lengthen their stems, producing taller plants and possibly greater yields. In agriculture, this hormone is frequently used to encourage the growth of several crops, including sugarcane.
