Prunus domestica, commonly known as Plum is a juicy and delicious fruits that belong to the genus Prunus of the Rosaceae family which also includes peaches, apricots, and nectarines. The plant is native to Southwest Asia. It is an ancient domesticated species, known only in cultivation, that is now cultivated in temperate areas worldwide for its fruit.
The species, which was first recorded in cultivation by the Syrians and then the Romans, and spread to western Europe during the Crusades, is likely derived from one or a combination of several Eurasian progenitors: cherry plum (P. salicifera); sloe (P. spinosa); and damson plum (P. insititia). It small to medium size, deciduous tree grow for its fruit. Plums are one of the most popular of the stone fruits.
Plum is a small, branched, deciduous tree that grows about 9 to 15 m (29 to 50 ft.) tall. It prefers a sunny well-drained, fertile soil. Clay loams are tolerated as long as drainage is good. Sandy soils are also suitable mainly if they are attached on nematode resistant rootstock.
The plant has reddish-brown, glabrous branches, unarmed or armed with few spines. Branchlets are reddish-brown to greyish-green, and are pubescent. The plant has reddish to brown bark. 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 like home gardens. Its early flowering and fruiting means that they require a sheltered spot away from frosts and cold winds for the better development of the plant. For the Essential Guide To Plum Tree Gardening
Leaves are alternate, deep green, elliptic to obovate, 4–10 × 2.5–5 cm, pubescent below, glabrous above, margins serrulate, apex acute to obtuse, base cuneate with a pair of nectaries, and with 5–7 pairs of lateral veins.
Flower is solitary or in fascicles of 3 at the tip of branchlets, pedicellate (10–12 mm), 10–15 mm across. Hypanthium is pubescent; sepals 5, ovate with acute apex, imbricate; petals 5, white or greenish-white, obovate, apex rounded to obtuse, imbricate, on rim of hypanthium; stamens 20–30, in 2 whorls; filaments unequal; carpel 1; ovary superior, 1-loculed, glabrous or sometimes villous; style terminal, elongated. Flowering normally takes place from April.
Globose to oblong, rarely sub globose fruit varies in size, but can be measuring about 5-6 cm in diameter with a hard, stony, flattened pit. The fruit is green when young turning to red, purple, purple black, yellow or golden yellow, often with a glaucous (white waxy) bloom on the surface. It is really an epicuticular wax covering and is also referred to as “wax bloom”. Skin is smooth yellow or dark red to purple or black. Inner flesh varies widely from creamy yellow, crimson, light-blue or light-green in color depending upon the cultivar type. The fruit has pleasant aroma and sweet and tart taste. Some varieties are usually sweet (dessert plum), though some varieties are sour and require cooking with sugar to make them palatable. Like all Prunus fruits, it contains a single large seed, usually called a stone, which is discarded when eating. An average weight of the fruit is about 50-70 g.
History of Plums
Prunus domestica is supposed to have originated in the area of the Caucusus and Asia Minor. First findings of primitive cultivars were reported to occur in Central Europe about 500 BC, probably known already by the Celtic and Teutonic tribes. Subsequently the fruit was dispersed to countries in central Europe by the Romans. It is probable that high quality cultivars originated from southeast Europe after the middle Ages, and distributed throughout Europe by the seventeenth century. Plum is now cultivated globally in temperate to warm-temperate regions, mostly in Central, S and SE Europe, further on in N Africa, W Asia, India and North America, Australia, New Zealand, South Africa and in South America.
