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. Each plant receives ...
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 ...
The ability to produce seedless fruit when pollination is unsuccessful may be an advantage to a plant because it provides food for the plant's seed dispersers. Without a fruit crop, the seed dispersing animals may starve or migrate. In some plants, pollination or another stimulation is required for parthenocarpy, termed stimulative parthenocarpy.

One particularly interesting case is the Prunus SI systems, which functions through self-recognition [15] (the cytotoxic activity of the S-RNAses is inhibited by default and selectively activated by the pollen partner SFB upon self-pollination), [where "SFB" is a term that stands "for S-haplotype-specific F-box protein", as explained ...
One property that results from nested structure of pollination networks is an asymmetry in specialization, where specialist species are often interacting with some of the most generalized species. This is in contrast to the idea of reciprocal specialization, where specialist pollinators interact with specialist plants. [ 6 ]
Seeds can disperse by rain or ice or be submerged in water. Seeds dispersed by water need to have the ability to float and resist water damage. They often have hairs to assist with enlargement and floating. More features that cause floating are air space, lightweight tissues and corky tissues. Hydrochory syndromes are most common in aquatic plants.
The plant the pollen is taken from is called the pollen donor or pollen parent, while the plant receiving the pollen is the seed parent. Hand-pollination is often done with a cotton swab or small brush, but can also be done by removing the petals from a male flower and brushing it against the stigmas of female flowers, or by simply shaking ...
