Question

What are the examples of plants with unisexual flowers that do not require emasculation?

Options

• Maize and sunflower

• Cucumber and bitter gourd

• Wheat, rice, and tomato

• Barley and oat

Answer 1

Cucumber and bitter gourd are examples of plants with unisexual flowers. In these plants, the female parent has only female flowers without anthers, so emasculation is not necessary. The flowers are bagged before opening, and when the stigma becomes receptive, they are pollinated with desired pollen and rebagged.
