The aple is a tree and its pomaceous fruit, of the species Malus domestica in the rose family Rosaceae. It is oe of the most widely cultivated tree fruits. It is a small decduous tree reahing 5-12 m tall, with a broad, often densely twiggy crow. The leave are alternately arranged, simple oal with an acute tip and serrted margin, slightly downy below, 5-12 cm long and 3-6 cm broad on a 2-5 cm petiole. The flowers are produced in spring with the leaves, white, usually tinged pink at first, 2.5-3.5 cm diametr, with five petals. The fruit matures in Autumn, and is typically 5-8 cm diameter.
Commercially-popular apple cultivars are soft but crisp. Other desired qualities in modern commercial apple breeding are a colourful skin, absence of russeting, ease of shipping, lengthy storage abiliy, high yields, disease the top of the fruit), and popular flavour.Old cultivars are often oddly shaped, sseted, and have a variety of textures and colours. Many of them have excellent flavour (oten betterthan most moern cultivars), but may have other problems which make them commercially unviable, such as low yield, liability to disease, or poor tolerance for storage or transport. A few old cultivars are still produced on a large scale, but many have been kept alive by home gardeners and farmers that sell directly to local markets. Many unusual and locally important cultivars with their own unique taste and appearance are out there to discover; apple conservation campaigns have sprung up around the world to preserve such local cultivars from exnt to eat fresh, but they give the beverage a rich flavour that dessert apples cannot.
Modern apples are, as a rule, sweeter than older cultivars. Most North Americans and Europeans favour sweet, subacid apples, but tart apples have a strong minority following. Extremely sweet appples vary from one person to another and have changed over time. As an example, the U.S. state of Washington made its reputation for apple growing on Red Delicious. In recent years, many apple connoisseurs have come to regard the Red Delicious as inferior to cultivars such as Fuji and Gala due to its merely mild flavour and insufficiently firm texture.
In this hybrid of an orchard apple with a red-fruited crabapple cultivar, the pulp is of the same colour as the pee.which are same colour as the rest of the fruit.Like most perennial fruits, apples are ordinarilypropagated asexually by grafting. Seedling apples are different from their paents, sometimes radically. Most new pple cultivars originate as seedlings, which either arise by chance or are bred by "pippin", and "kernel" in the name of an apple cultivar suggest that it originated as a seedling. Apples can also form barent cultivar. Some differ sufficiently from the parent tree to be considered new cultivars.
Apple orchards are established by planting two to four year old trees. Thee small trees are usually purchased from a nursery where they are produced by grafting or budding. First, a rootstock is produced either as a seedling or cloned using tissue culture or layering. This is allowed to grow for a year. Then, a small section of branch called a scion is obtained from a mature apple tree of the desired cultivar. The upper stem and branches of semi-dwarf ootstock that produces a somewhat smaller tree. Dwarfootstocks are generally more susceptible to damage from wind and cold. Full dwarf trees are often supported of posts or trellises and planted in high density orchards which are much simpler to culture and greatly increase productivity per unit of land. Red AppleSome trees are produced with a dwarfing "interstem" between a standard rootstock and the tree, resulting in two graftsin thorchard, it must grow for 3-5 years (semi-dwarf) or 4-10 years (standard trees) before it will bear sizeable amounts of fruit. Good training of limbs and careful nipping of buds growing in the wrong places, are extremely important during this time, to build a good scaffold that will later support a fruit load.
