The process of transfer of pollen grains from the anther of one flower to the stigma of another flower (on a different individual of the same species) is called cross-pollination. The plants have to depend upon various external agencies. Cross pollination is the transfer of pollen grains from the anther of a flower to the stigma of a flower of a different plant of the same species. New varieties may be produced by cross-pollinating two different varieties of the same species. Chances are high that desirable qualities may get eliminated and unwanted characteristics may get added due to recombination of genes. Also even beneficial gene can't be passed rapidly to other plants just offspring of the one plant. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma. 4. 4. Cross pollination is advantageous because it allows for diversity in the species, as the genetic information of different plants are combined. The following are the advantages of cross-pollination. Two main types of this process are cross-pollination and self-pollination, and each of these types has subcategories that we will go over in deeper detail. New varieties of plants and crops can be developed through cross pollination. More genetically diverse plant communities have a higher chance of surviving because some plants may have genetic features that allow them to thrive while others in the community die off.
Dichogamy - an overview | ScienceDirect Topics Another situation in which artificial pollination is useful is when natural pollination processes are slow or non-existent. 5.
