The words pollenizer (polleniser) and pollinator are often confused. A pollenizer is the plant that provides pollen. A pollenizer is always a plant. A pollinator is the biotic agent that moves the pollen, whether it be bees, moths, bats, or birds, etc. Pollination is an important step in the reproduction of seed plants: the transfer of pollen grains (male gametes) to the plant carpel, the structure that contains the ovule (female gamete). ...

The verb form to pollenize, is to be the source of pollen, or to be the sire of the next plant generation.

While some plants are capable of self pollenization, the term is more often used in pollination management as a plant that provides abundant, compatible, and viable pollen at the same flowering time as the pollenized plant. For example most crabapple varieties are good pollenizers for any apple variety that blooms at the same time, and are often used in apple orchards for the purpose. Some apple cultivars produce very little pollen; some produce pollen that is sterile, or incompatible with other apple varieties. These are poor pollenizers. Pollination Management is the label for horticultural practices that accomplish or enhance pollination of a crop, to improve yield or quality, by understanding of the particular crops pollination needs, and by knowledgeable management of pollenizers, pollinators, and pollination conditions. ...

A pollenizer can also be the male plant in dioecious species (where entire plants are of a single sex), such as with kiwi fruit or holly. Plant sexuality deals with the wide variety of sexual reproduction systems found across the plant kingdom. ...

Plants are sometimes mistakenly called pollinators. For example, some nursery catalogs may say variety X should be planted as a pollinator for variety Y, when they actually should be referring to it as a pollenizer. Strictly, a plant can only be a pollinator when it is self fertile and it physically pollinates itself without the aid of an external pollinator, as in the case of apomictic species like some rowans and hawthorns. A nursery is a place where plants are propagated, usually for sale as a business, though some gardeners and farmers keep private nurseries. ... In botany, apomixis is biological reproduction without fertilization, meiosis or production of gametes, with the result that the seeds are genetically identical to the parent plant. ...
