प्रश्न
Lever mechanism of pollination is observed in
- Salvia
- Jasmine
- Bougainvillea
- Butea
उत्तर
(a) Salvia
In Salvia, when an insect visits a flower, it pushes the lower sterile anther lobe due to which the upper fertile anther lobe bends down. The anther lobe comes in contact with the rear of the insect's body where the pollen grains get attached. When the same insect visits another flower with a mature gynoecium, the pollen grains are picked up by the receptive stigma. This process of pollination is called the lever mechanism.
