The stamen of a corn plant, showing the pollen.. Pollen drift is the accidental cross-pollination of different varieties of crops through natural dispersal methods. The term is used almost exclusively when referring to strains of corn, and especially refers to the crossing of genetically modified crops with those that are not.
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [ 1 ] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set.
Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.

Saturation pollination is a pollination technique for agricultural crops in areas dominated by non-crop plant species that are preferred by pollinators. The technique involves keeping a larger number of bee colonies than normally maintained for honey production so as to exhaust the preferred plants and ensure visitation of the crop plants by the bees.
