Prunus americana, commonly called the American plum, [7] wild plum, or Marshall's large yellow sweet plum, is a species of Prunus native to North America from Saskatchewan and Idaho south to New Mexico and east to Québec, Maine and Florida. [8] Prunus americana has often been planted outside its native range and sometimes escapes cultivation. [9]
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.
Whereas plumcots and apriplums are first-generation hybrids between a plum parent (P. salicina [1]) and an apricot (P. armeniaca), pluots and apriums are later-generations. [ 2 ] [ 3 ] Both names "plumcot" and "apriplum" have been used for trees derived from a plum seed parent, and are therefore equivalent.
In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years. [1] Much is known about fruit tree pollination in temperate climates, but much less is known about fruit tree pollination in tropical climates. [1]
The Japanese plum, like other Prunus fruit tree species, is mostly self-incompatible and requires cross pollination to ensure fruit set because this genus is unable to bear fruit parthenocarpically. Several cultivars or varieties have however been identified with self-compatibility. [8]
Prunus angustifolia, known commonly as Chickasaw plum, Cherokee plum, Florida sand plum, sandhill plum, or sand plum, [3] is a North American species of plum-bearing tree. . It was originally cultivated by Native Americans before the arrival of Europe
Ziziphus mauritiana, also known as Indian jujube, [2] Indian plum, [2] Chinese date, [2] Chinee apple, [2] ber [2] and dunks [2] is a tropical fruit tree species belonging to the family Rhamnaceae. It is often confused with the closely related Chinese jujube ( Z. jujuba ), but whereas Z. jujuba prefers temperate climates, Z. mauritiana is ...
P. nigra has the same number of chromosomes as P. salicina, the cultivated Japanese plum, and so the two cross-pollinate readily. [17] Breeding work in the 20th century resulted in improved P. nigra x salicina hybrid varieties that retain the high quality of Japanese plums and the hardiness of wild Canada plums, such as "Pembina", "Superior ...
