Pollination is the process of transferring pollen from the male anther of a flower to the female stigma. The pollen then germinates and produces a pollen tube, which grows down the style to the ovary, where it fertilizes the ovules. Pollination occurs in many flowering plants, including zucchini.
Zucchini plants have separate male and female flowers. The male flowers are located on the main stem of the plant, while the female flowers are located on the side branches. The male flowers are easily identified by their long, thin stems and their large, yellow petals. The female flowers are smaller than the male flowers and have a small, round ovary at their base.
