  What is pollination? Pollination is an annual challenge for growers when it comes to the production of vegetables, fruit and seed. Well pollinated crops [...] these products. Pollination is the transfer of pollen from the anthers of the flower to the stigma of the flower. If the pollen is transferred from anther [...] anther to stigma on the same flower it is called self-pollination.
