1.2- Species Cydonia oblonga Mill. - Quince tree
+ Overview
The Quince (Cydonia oblonga) is the sole member of the genus Cydonia in the Genus Cydonia, in the Subtribe Malinae, in the Tribe Maleae, in ther family Rosaceae (which also contains apples and pears, among other fruits) of the Order Rosales. It is a small deciduous tree that bears a pome fruit, similar in appearance to a pear, and bright golden-yellow when mature. Throughout history the cooked fruit has been used as food, but the tree is also grown for its attractive pale pink blossoms and other ornamental qualities.
As the quince is native to warm-temperate regions, it is believed that the fruits of this tree are more sweet and juicy when grown in hotter climatic conditions than cooler regions. When grown in cooler climatic conditions, the quince fruits are prone to become extremely sharp-tasting and have a somewhat fibrous surface. Hence, quinces grown in England needs to be boiled, sweetened and, at times, filtering before they become edible. Hence, most of the English quinces are used to prepare jellies and marmalades.
Quince is used as a food plant by the larvae of some Lepidoptera species including brown-tail, Bucculatrix bechsteinella, Bucculatrix pomifoliella, Coleophora cerasivorella, Coleophora malivorella, green pug and winter moth.

+ The names
The botanical name of the tree ‘Cydonia' denotes Cydon located on the island of Crete - where the best variety of quince trees is found. The general name of the tree has been drawn from the term ‘quints' denoting the plural of the old French name for the quince fruit.
The fruit was known to the Akkadians, who called it supurgillu; Arabic سفرجل al safarjal "quinces" (collective plural).
The modern name originated in the 14th century as a plural of quoyn, via Old French cooin from Latin cotoneum malum / cydonium malum, ultimately from Greek κυδώνιον μλον, kydonion melon "Kydonian apple".
The quince has close association with the Japanese quince called ‘japonica' or Chaenomeles japonica. This species is well accepted as a garden decorative tree, but it hardly ever bears fruit when grown in cooler climatic conditions.

2- Characteristics of the Quince tree
2.1- Description
+ The plant
Quince is a deciduous, unarmed, perennial shrub or small tree 5 to 8 meters (16 to 26 ft.) high and 4 to 6 meters (13 to 20 ft.) wide with crowded gnarled branches and branchlets.
Branchlets are normally purplish red when young, turning purplish brown with age, terete, initially densely tomentose becoming glabrous when old.
+ The leaves
The leaves are alternately arranged, simple, 6-11 cm (2-4 in) long, with an entire margin and densely pubescent with fine white hairs.
Lamina is simple, ovate to oblong, 5-10 × 3-5 cm, lower surface pale green with conspicuous veins and densely villous, upper surface dark green glabrous or sparsely pubescent when young, base rounded or sub-cordate, margin entire, apex acute or emarginate.
+ The flowers
Flowers are white or pink, 5 cm (2 in) across on tomentose pedicel with caducous, ovate bracts with campanulate hypanthium which is densely tomentose abaxially; ovate or broadly lanceolate, 5-6 mm, both surfaces tomentose, margin glandular serrate, apex acute; with five petals, white or pinkish, 1.8 cm long; stamens less than 1/2 as long as petals. Styles are nearly as long as stamens, densely villous basally.
+ The fruits
Quince plant offers fragrant, pear-shaped fruit, 7 to 12 centimeters (2.8 to 4.7 in) long and 6 to 9 centimeters (2.4 to 3.5 in) across, densely tomentose with tenacious reflexed sepals and stout, tomentose fruiting pedicel, 5 mm long.
Pulp is firm, fleshy and aromatic. Fruit is normally light green while young turning yellow as soon as they ripe. The fruit is larger than average apple and bumpy; appear somewhat like large guava, avocado, or as short-necked pear fruit. Its fuzzy surface is smooth as in peaches. Quince fruit weighs about 250-750 g or more in some varieties.
The immature fruit is green with dense grey-white pubescence, most of which rubs off before maturity in late autumn when the fruit changes color to yellow with hard, strongly perfumed flesh.
External skin is normally fuzzy and has light yellow, gritty flesh. Fruit has intense fruity aroma and has astringent, acidulous taste. They are too hard, too tart, too acidic, too sour, and too generally unpleasant in taste and texture to eat raw. Sufficient cooking, however, softens them and brings out the floral aroma they hold deep inside along with a lovely sweetness.
+ The seeds
The seeds of the quince fruit possess gentle, but dependable laxative, anti-inflammatory and astringent properties. The seeds puff up when placed in water and forms a sticky substance that has a comforting and softening action when used internally. This sticky mass formed by soaking the seeds in water is used to heal respiratory ailments, particularly in children.
The seeds of the fruit may be used to prepare a pleasant and therapeutic drink. To prepare the drink grind dried seeds and boil them in water for about five minutes.

2.2- Origin and Distribution
+ Origin
The Quince tree (Cydonia oblonga) is native to rocky slopes and woodland margins in South-West Asia, Turkey and Iran although it can be grown successfully at latitudes as far north as Scotland.
+ Distribution
Quince was introduced to the New World, Australia and New Zealand, where in some locations it has grown wild. It has become rare in North America due to its susceptibility to fireblight disease caused by the bacterium Erwinia amylovora. Quinces are widely grown in Argentina, Chile and Uruguay. Almost all of the quinces in North American specialty markets come from Argentina.
It should not be confused with its relatives, the Chinese quince, Pseudocydonia sinensis, or the flowering quinces of genus Chaenomeles, either of which are sometimes used as culinary substitutes.
Top 10 of Quince producers in 2012 are:
1- Turkey, 2- China, 3- Uzbekistan, 4- Morocco, 5- Iran, 6- Argentina, 7- Azerbaijan, 8- Spain, 9- Serbia and 10- Algeria.

2.4- Nutrition of the Quince fruit
+ Overview
Quince is low calorie fruit. 100 g fresh raw fruit provides 57 calories. In addition, it composes several vital poly-phenolic antioxidants than apples and pears. The fruit is a storehouse of phyto-nutrients such as dietary fiber, minerals, and vitamins.
Quince flesh along with its peel contains good amounts of fiber. Further, its gritty granules in the pulp composed of astringent compounds known as tannins namely, catechin and epicatechin. They bind to cancer-causing toxins and chemicals in the colon, and thereby protecting its mucous membrane from inflammatory bowel disease (IBD), cancers, and diverticulitis. In addition, it helps reduce body weight and blood LDL cholesterol levels.
It has several phenolic compounds such as caffeoylquinic acid, procyanidin-B2, oligomeric procyanidin, polymeric procyanidin etc., and essential oils like furfural, limonene, linalol, vomifoliol, toluene, ß-ionone, a-terpineol, etc. Together; these compounds give quince its unique fragrance.
Ripe quince fruit has good concentration of vitamin C. 100 g fruit provides 15 mg or 25% of RDA of vitamin-C. Fruits rich in this vitamin help remove harmful oxygen-free radicals from the body. Vitamin C helps boost immunity, reduce viral episodes and inflammatory conditions.
It is a good source of minerals such as copper (130 µg or 14% of RDA), iron, potassium, and magnesium as well as B-complex vitamins such as thiamin, riboflavin and pyridoxine (vitamin B-6).
Although not well documented, quince fruit, like pears, has anti-allergenic and anti-inflammatory properties. The fruit as well its seed's extraction suggested in the treatment of cystitis, atopic dermatitis, recommended by health practitioners as a safe alternative in the preparation of food products for allergic people.

3- The Uses of Quince
3.1- Food Uses
The quince fruit may be consumed raw or in a cooked form. When the trees are cultivated in warm temperate or tropical climatic conditions, the quince fruits may be soft and juicy, appropriate for being consumed raw. In addition, the fruit may also be used to prepare jams, jellies, marmalades and other preserves. When the fruit is cooked with apples it adds to the latter's flavor. The quince fruits have a strong fragrance, but are tough and have a somewhat coarse flesh. The fruits are approximately 10 cm long and 9 cm wide getting thinner at the base.
Some varieties of quince, such as 'Aromatnaya' and 'Kuganskaya' do not require cooking and can be eaten raw. However, most varieties of quince are too hard, astringent and sour to eat raw unless "bletted" (softened by frost and subsequent decay). High in pectin, they are used to make jam, jelly and quince pudding, or they may be peeled, then roasted, baked or stewed; pectin levels diminish as the fruit ripens. The flesh of the fruit turns red after a long cooking time. The very strong perfume means they can be added in small quantities to apple pies and jam to enhance the flavor. Adding a diced quince to apple sauce will enhance the taste of the apple sauce with the chunks of relatively firm, tart quince. The term "marmalade", originally meaning a quince jam, derives from marmelo, the Portuguese word for this fruit.
The fruit can be used to make a type of wine. Because of its often high acidity, which is mainly due to its malic acid content, these wines are usually sweet dessert wines that are high in alcohol. In the Balkans and elsewhere, quince brandy and quince liqueur are made.
