Biology Question on plant growth and development
Production of Cucumber has increased manifold in recent years. Application of which of the following phytohormones has resulted in this increased yield as the hormone is known to produce female flowers in the plants?
A
ABA
B
Gibberellin
C
Ethylene
D
Cytokinin
Answer
Ethylene
Explanation
Solution
Ethylene is a plant growth regulator (PGR) that exists in a gaseous state. Its application can induce a feminizing effect in Pineapple (Bromeliaceae) and Cucumber, promoting femaleness in these plants. In Cucumber plants, the application of Ethylene can increase the number of female flowers, ultimately leading to a higher final yield.
As a result, farmers can apply Ethylene to boost the number of female flowers in their cucumber plants.
