As sedentary organisms, plants usually must enlist the services of external agents for pollen transport. In flowering plants, these are (roughly in order of diminishing importance) insects, wind, birds, mammals, and water. See also major types of pollinators. Types: self-pollination and cross-...

In contrast,cross-pollinationis the transfer of pollen from the anther in a flower in one plant to the stigma in a separate flower in another plant. Cross-pollination, therefore, necessarily involves two flowers and two plants. Consequently, self-pollination results ininbreedingor selfing in whic...
The primary method of sexual reproduction in plants is pollination. The pollen grain is also known as a microspore, and the transportation of a microspore from an anther to the stigma of a flower is known as pollination. To pollinate themselves, plants use biotic and abiotic agents. Animals li...
Insects are the major agents of pollination, seed predation, or seed dispersal in many ecosystems. Animal pollinators are critical to pollination and survival of many plant species that typically occur as widely scattered individuals, especially in deserts and tropical forests. Seed predators often ...
The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant. Insects and wind are agents of cross-pollination. cross-pollinateverb ...
The cages were sealed all around with soil at the ground level to prevent the entry of pollinating agents and other insects. Adequate plant protection measures were taken inside the cage. A large number of accessions can be regenerated at a time safely and cost-effectively under cages, even ...
studies of pollination are invaluable for understanding the evolution of flowering plants and their distribution in the world today. As sedentary organisms, plants usually must enlist the services of external agents for pollen transport. In flowering plants, these are (roughly in order of diminishing ...
and the timing of the maturation of stamens and pistils of the same flower or plant. Cross-pollination may then be brought about by a number of agents, chiefly insects and wind. Wind-pollinated flowers generally can be recognized by their lack of color, odor, or nectar and their stigmas...
