Pollination is a most important ecosystem service provided by insects and others resulting in
sustainability and stability of the community life. Plants and animals particularly insects
largely interact at the point of pollination and this relationship are vital to continue
functioning and existence of plants and animals in balance and stable state. The ultimate
fruits production depend upon a number of aspects such as flowering period, floral
morphology, anthesis, pollen morphology, pollen productivity, stigma morphology, stigma
receptivity, flower-visitors interaction and their foraging behaviour. Lack of pollinators may
make pollen transfer difficult. So the relationship between the flower and visitor is one of the
most critical parts of plant reproduction as well as pollen dispersal and pollination.
The uniqueness and specific features regarding the architecture of flower are of great
significance in relation to pollination mechanism and co-evolutionary studies of flowering
plants. Pollen-pistil interaction is one of the fine examples of co-adaptation between the male
and female partners. There is a continuous process between the pollen and the pistil
beginning with pollination until the pollen tube enters the ovule. The understanding of pollen-
pistil interaction essentially involves gaining knowledge on pollination. Heteroanthery,
heterostyly, (distyly and tristyly) conditions were found in some plants which indicate
necessity of some agents for transferring pollen grains from anther to stigma. All the
contrivances ensure cross-pollination nature of these plants.
