Spraying sugarcane crop with which of the following plant growth regulators, increases the length of stem,thus, increasing the yield?
- Auxin
- Gibberellin
- Cytokinin
- Abscisic acid
The Correct Option is B
Approach Solution - 1
Gibberellin is a plant hormone that promotes growth, especially stem elon gation. When sprayed on sugarcane, it increases the stem length and enhances overall crop yield.
Cytokinins promote cell division, while auxins influence root development, and abscisic acid is involved in stress responses.
Approach Solution -2
Step 1: Gibberellin is a plant growth regulator that promotes stem elongation. When applied to sugarcane, it increases the length of the stem, leading to improved yield.
Step 2: Gibberellin is known for its role in promoting growth, especially in terms of stem elongation and overall plant height.
Thus, the correct answer is (2) Gibberellin.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector\(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
