Peach blossoms (including nectarine), most cherry blossoms, and some almond blossoms are usually pink. Plum blossoms, apple blossoms, orange blossoms, some cherry blossoms, and most almond blossoms are white. [1] Blossoms provide pollen to pollinators such as bees, and initiate cross-pollination necessary for the trees to reproduce by producing ...
Pollination by a specialist can result in high flowering synchrony, as asynchronous flowering can result in erratic attraction of a specialist to a site. [19] Showy floral displays tend to attract pollinators, [20] [21] and synchronous flowering can attract more pollinators to a population. High pollinator visitation to populations with high ...
Plants adapted for cross-pollination have several mechanisms to prevent self-pollination; the reproductive organs may be arranged in such a way that self-fertilisation is unlikely, or the stamens and carpels may mature at different times. [8] Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the ...
Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant. The main characteristics which facilitate cross-pollination are: Herkogamy : Flowers possess some mechanical barrier on their stigmatic surface to avoid self-pollination, e.g. presence of gynostegium and pollinia ...
Anthecology, or pollination biology, is the study of pollination as well as the relationships between flowers and their pollinators. [1]: 8 Floral biology is a bigger field that includes these studies. Most flowering plants, or angiosperms, are pollinated by animals, and especially by insects. [2]
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 ]

The floral scent of Asimina triloba has been described as "yeasty", which is one of several features that signify a "beetle pollination syndrome". [36] Other floral features of pawpaw indicative of beetle pollination include petals that curve over the downward-pointing flower center, along with food-rich fleshy bases of the inner whorl of petals.
