Prunus sect. Prunocerasus (meaning plum-cherry) is a section of the genus Prunus. Koehne originally described it as comprising the North American plums and placed it in the subgenus Cerasus. [1] The section is now generally recognized as belonging to Prunus subg. Prunus. [2] Species attributed to this section include: P. alleghaniensis Porter
Included in this genus are multiple species of trees and shrubs, such as: Dibotryon morbosum infects are Prunus serotina (wild cherry trees), Prunus persica (peach trees), Prunus domestica (plum trees), and Prunus cerasus (sour cherry trees). [3] The main symptom of Dibotryon morbosum is its “knot-like” gall structure. These knots can vary ...
Prunus is a genus of flowering trees and shrubs from the family Rosaceae, which includes plums, cherries, peaches, nectarines, apricots and almonds (collectively stonefruit).The genus has a cosmopolitan distribution, [4] being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, [5] There are about 340 ...
Regulatory pruning: This is carried out on the tree as a whole, and is aimed at keeping the tree and its environment healthy, e.g., by keeping the centre open so that air can circulate; removing dead or diseased wood; preventing branches from becoming overcrowded (branches should be roughly 50 cm (20 in) apart and spurs not less than 25 cm (10 ...
Plums are grown commercially in orchards, but modern rootstocks, together with self-fertile strains, training and pruning methods, allow single plums to be grown in relatively small spaces. Their early flowering and fruiting means that they require a sheltered spot away from frosts and cold winds.
Plums are a diverse group of species. The commercially important plum trees are medium-sized, usually pruned to 5–6 metres (16–20 ft) height. The tree is of medium hardiness. [13] Without pruning, the trees can reach 12 metres (39 ft) in height and spread across 10 metres (33 ft).
It can be found at 900–3,400 m (3,000–10,000 ft) above sea level. It is a canopy tree 30–40 m in height, and is the tallest member of Prunus. [4] Large-diameter trees have impressive, spreading crowns. It requires a moist climate, 900–3,400 mm (35–130 in) annual rainfall, and is moderately frost-tolerant.
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]
