Origin

Papaya origins are rather uncertain, but there is some agreement among botanists that it originated in the lowlands of Central America, between southern Mexico and Nicaragua. Early distribution over a wide geographical region in Central and South America was aided by the abundance of seeds in the fruit and the seeds long viability8
It is recorded that seeds were taken to Panama and then the Dominican Republic before 1525 and cultivation spread to warm elevations throughout South and Central America, southern Mexico, the West Indies and Bahamas, and to Bermuda in 1616. Spaniards carried seeds to the Philippines about 1550 and the papaya traveled from there to Malacca and India. Seeds were sent from India to Naples in 1626. Now the papaya is familiar in nearly all tropical regions of the Old World and the Pacific Islands and has become naturalized in many areas. Seeds were probably brought to Florida from the Bahamas. 4

Origin of the Papaya, Tropical Fruit News, RFCI

Description
Papaya (Carica papaya L.) is a popular fruit native to tropical America. It is usually grown for its small to large melon-like fruit. It is a herbaceous perennial, bearing fruit continuously at the leaf axils spirally arranged along the single erect trunk. The cultivated papaya belongs to the family Caricaceae and is the only member of the genus Carica. 8
Enormous, simple, lobed leaves combine with a single trunk and delicious fruit to make this a desirable plant for many landscapes. Flowers are produced along the trunk from the leaf axil. Flowers on male plants are more conspicuous and showy; female flowers are borne close to the stem and usually go unnoticed. Fruit are produced in the leaf axil close to the trunk. The trunk becomes thickened, occasionally growing to 12 inches in diameter. Although older plants can reach 20 feet tall or more, most reach only 15 feet before dying. Plants are short lived but grow quickly. 2

Leaves
The leaves emerge directly from the upper part of the stem in a spiral on nearly horizontal petioles 1 to 3-½ feet long. The blade, deeply divided into 5 to 9 main segments, varies from 1 to 2 feet in width, and has prominent yellowish ribs and veins. The life of a leaf is 4 to 6 months. 9

Flowers
There are three primary groups of fl owers, i.e. pistillate, staminate and hermaphrodite, with many variants, especially in the hermaphrodite group. 8
The 5-petalled flowers are fleshy, waxy and slightly fragrant. Some plants bear only short-stalked pistillate (female) flowers, waxy and ivory-white; or hermaprodite (perfect) flowers (having female and male organs), ivory-white with bright-yellow anthers and borne on short stalks; while others may bear only staminate (male) flowers, clustered on panicles to 5 or 6 ft (1.5-1.8 m) long. There may even be monoecious plants having both male and female flowers. 4

Pollination
Papaya is a polygamous species with 3 basic plant types. Male (staminate) plants, in which small, tubular, yellow flowers possessing 10 anthers are held in cymes at the ends of long peduncles (Fig. 7)Female (pistillate) plants with large yellow to whitish flowers which possess a large, superior ovary which is held on a much-reduced cyme in the leaf axils along the trunk (Fig. 17)Bisexual (hermaphroditic) plants possess perfect flowers held on a much-reduced cyme in the leaf axils along the trunk. 1
Papaya plants may be self-pollinating (bisexual plants) or cross pollinated by insects and wind. Pollinators include honey bees, wasps, midges, thrips, surphid flies, and butterflies. 1
Unpollinated female plants occasionally set parthenocarpic fruits, lacking seeds. Hermaphrodite plants tend to produce self-pollinated seeds, which result in relatively uniform progenies. 11

Fruit
There are two types of papayas, Hawaiian and Mexican. The Hawaiian varieties are the papayas commonly found in supermarkets. These pear-shaped fruit generally weigh about 1 pound and have yellow skin when ripe. The flesh is bright orange or pinkish, depending on variety, with small black seeds clustered in the center. Hawaiian papayas are easier to harvest because the plants seldom grow taller than 8 feet. Mexican papayas are much larger the the Hawaiian types and may weigh up to 10 pounds and be more than 15 inches long. The flesh may be yellow, orange or pink. 9
Generally, the fruit is melon-like, oval to nearly round, or elongated, 15-50 cm long and 10-20 cm thick; weighing over 10 kg. The skin is waxy and thin but fairly tough. When the fruit is green and hard it is rich in white latex. As it ripens, it becomes light or deep-yellow externally and the thick wall of succulent flesh becomes aromatic, yellow, orange or various shades of salmon or red. It is then juicy, sweetish and somewhat like a cantaloupe in flavour; in some types quite musky. Attached lightly to the wall by soft, white, fibrous tissue, are usually numerous small, black, peppery seeds about 5 mm long, each coated with a transparent, gelatinous aril. 5
The shape of the cavity at the transverse cut ranges from star-shape with 5-7 furrows, to smooth and circular in shape. 8
Female plants produce medium to large round-shaped fruit of good quality and a large seed cavity. Bisexual plants produce small to large elongated fruit of good quality and a smaller seed cavity. Male plants with bisexual flowers may produce a few, elongated, pear-shaped, poor quality fruit. 1
The papaya fruit skin has a network of lactifers which, in immature fruits contains an abundance of milky, proteolytic latex called papain. The papain is under pressure and spurts out when the skin is pricked. The lactifers collapse as the fruit ripens and there is little or no latex at the fully ripe stage. 5

Varieties

There are numerous varieties of papaya. However, very few are available to most urban residents because of the seeds are not commonly for sale in small amounts. Important varieties in the U.S. include 'Red Lady', 'Maradol', and various Solo-types. 1

Harvesting
Well-cared-for plants may begin to produce flowers 4 months after planting and fruit 7 to 11 months after planting. The amount of fruit produced by a papaya plant varies with the general climate, weather conditions during the year, and plant care. Yields vary from 60 to 80 lbs per tree over a 12 month period. 1
Home gardeners should take steps to avoid having only a single papaya plant, in case it turns out to be a female. One way to accomplish this is have several plants in the garden, to ensure the possibility that at least one will be a hermaphrodite with pollen. 3

Propagation
Papaya is mainly propagated by seed. The sarcotesta enveloping the seed is removed (because it inhibits germination) by rubbing the seed together against a fine-meshed screen under running water. Thoroughly dried seeds stored in air-tight containers remain viable for several years. The sex of the plant is determined by its parents. 1,10
Papaya plants can also be grown from cuttings, which should be hardened off for a few days and then propped up with the tip touching moist, fertile soil until roots form. Semihardwood cuttings planted during the summer root rapidly and should fruit the following year. 9

Planting
Papaya plants should be planted in full sun and at least 10 to 20 ft (3.1-6.1 m) away from other plants, buildings, and power lines. In general, planting 2 to 3 papaya plants 7 to 12 ft (2.1-3.7 m) away from each other will insure that at least one will be fruitful, and it will also facilitate fertilizing and watering. 1
Overcrowded fruits should be thinned out when young to provide room for good form development and avoid pressure injury. After the first crop, the terminal growth may be nipped off to induce branching which tends to dwarf the plant and facilitates harvesting. Select the warmest area of the landscape that does not flood (or remain wet) after typical summer rainfall.

Pruning

Papaya plants are not pruned because their main growing point is terminal, and branched trees generally do not produce as well. If the main growing point is damage or killed, side sprouts may grow. Selecting 1 or 2 of the most vigorous shoots and removing the others will facilitate growth and fruiting of the remaining shoots. Tying these side shoots to a stake will reduce the chance they may break off due to a heavy fruit load or high winds. 1

Irrigation

Watering is essential for best papaya plant growth and fruit production. Papaya plants that lack water (drought stress) may drop flowers, leaves, and young fruit and produce small fruit of low sugar content. 1

Food Uses

Ripe papayas are most commonly eaten fresh, merely peeled, seeded, cut in wedges and served with a half or quarter of lime or lemon. Sometimes a few seeds are left attached for those who enjoy their peppery flavor but not many should be eaten. 4
Papayas are also processed into various forms, such as dehydrated slices, chunks and slices for tropical fruit salads and cocktails, or processed into puree for juices and nectar base, usually frozen, and as canned nectar, mixed drinks and jams. Papaya puree is the basis for remanufacturing of many products. 8

Nutrient Content
About 60% of the ripe fruit is edible. The approximate contents per 100 g edible portion are: water 86.6 g, protein 0.5 g, fat 0.3 g, carbohydrates 12.1 g, fibre 0.7 g, ash 0.5 g, potassium 204 mg, calcium 34 mg, phosphorus 11 mg, iron 1 mg, sodium 3 mg, vitamin A 450 mg, vitamin C 74 mg, thiamine 0.03 mg, niacin 0.5 mg, and riboflavin 0.04 mg. The energy value is 200 kJ/100 g. Major sugars are sucrose (48.3%), glucose (29.8%) and fructose (21.9%). 10

Medicinal Properties **
Studies at the University of Nigeria have revealed that extracts of ripe and unripe papaya fruits and of the seeds are active against gram-positive bacteria. Strong doses are effective against gram-negative bacteria. The substance has protein-like properties. The fresh crushed seeds yield the aglycone of glucotropaeolin benzyl isothiocyanate (BITC) which is bacteriostatic, bactericidal and fungicidal. A single effective does is 4-5 g seeds (25-30 mg BITC). 4

Papaya the Medicine Tree, Archives of the Rare Fruit Council of Australia

Other Uses
The latex of the papaya plant and its green fruits contains two proteolytic enzymes, papain and chymopapain. The latter is most abundant but papain is twice as potent. 4
Papain is a proteolytic enzyme that digests proteins and is used as a meat tenderizer, as a digestive medicine in the pharmaceutical industry, in beer brewing, tanning industries and in the manufacture of chewing gum. 8
Commercially, the skin is scarified to induce latex flow, which is allowed to dry then collected to be later processed into papain. 8

General

Caricaceae is a small family of dicotyledonous plants with six genera; four of tropical American origin (Carica, Jarilla, Jacaratia, Vasconcella) and one, Cylicomorpha, from equatorial Africa. Caricaceae species have been variously classified in families such as Cucurbitaceae, Passifloraceae, Bixaceae and Papayaceae. Approximately 71 species have been described, though Badillo (1993, 2000) reduced the number to 32 species, with the following distribution: Carica, 1 species, Cylicomorpha, 2 species, Jacaratia, 5 species, Jarilla, 3 species, Vasconcella, 20 species, and Horovitzia, 1 species. 8
The papaya is regarded as a fair source of iron and calcium; a good source of vitamins A, B and G and an excellent source of vitamin C (ascorbic acid).
