Hello student,

Pollination in salvia is favored by means of insects hence pollination is entomophilous. Self pollination is prevented in salvia as the flowers are protandrous. The petals of salvia are bifurcated. When an insects visit the flowers and sit on the petals, the stamens are brought down to the back of insect and pollens are laden on it. Hence, in this way cross pollination occurs.

Thank you.

Dear student,

Salvia does its pollination with the help of insects or it occurs by means of insects
Pollination follows turn pipe mechanism.
The petals of Salvia are bifurcated. When an insect visits a flower and sits on the petals, the stamens are brought down to the touch the back of insect and pollen are laden on it.
And when the insect visits another flower, cross pollination occurs.
