This article is about Carica papaya
, the widely cultivated papaya (also called papaw or pawpaw), a tropical fruit plant. For the mountain papaya (Vasconcellea pubescens
) of South America, see Mountain papaya
. For the Eastern North American tree (and fruit) called "pawpaw", see Asimina triloba
. For other uses, see Papaya (disambiguation)
) (from Carib
via Spanish), papaw
The papaya is a small, sparsely branched tree, usually with a single stem
growing from 5 to 10 m (16 to 33 ft) tall, with spirally arranged leaves
confined to the top of the trunk
. The lower trunk is conspicuously scarred
where leaves and fruit were borne. The leaves are large, 50–70 cm (20–28 in) in diameter
, deeply palmately
lobed, with seven lobes. All parts of the plant contain latex
in articulated laticifers.
Papayas are dioecious
. The flowers
are five-parted and highly dimorphic; the male flowers have the stamens fused to the petals. The female flowers have a superior ovary and five contorted petals loosely connected at the base.:235
Male and female flowers are borne in the leaf axils, and the males are multiflowered dichasia
, and the female flowers are in few-flowered dichasia.
The pollen grains are elongated and approximately 35 microns in length.
The flowers are sweet-scented, open at night, and wind- or insect-pollinated.
The fruit is a large berry
that is generally spherical or cylinder in form and about 15–45 cm (5.9–17.7 in) long and 10–30 cm (3.9–11.8 in) in diameter.:88
It is ripe
when it feels soft (as soft as a ripe avocado
or softer), its skin has attained an amber to orange hue and along the walls of the large central cavity are attached numerous black seeds.

Origin and distribution
Papayas with yellow flesh
Papaya plants grow in three sexes: male, female, and hermaphrodite
. The male produces only pollen
, never fruit. The female produces small, inedible fruits unless pollinated. The hermaphrodite can self-pollinate since its flowers contain both male stamens
and female ovaries
. Almost all commercial papaya orchards contain only hermaphrodites.
Originally from southern Mexico (particularly Chiapas
), Central America
, and northern South America
the papaya is now cultivated in most tropical countries. In cultivation, it grows rapidly, fruiting within 3 years. It is, however, highly frost-sensitive, limiting its production to tropical climates
. Temperatures below −2 °C (29 °F) are greatly harmful if not fatal. In Florida, California, and Texas, growth is generally limited to southern parts of those states. It prefers sandy, well-drained soil, as standing water can kill the plant within 24 hours.
Two kinds of papayas are commonly grown. One has sweet, red or orange flesh, and the other has yellow flesh; in Australia
, these are called "red papaya" and "yellow papaw", respectively.
Either kind, picked green, is called a "green papaya".
The large-fruited, red-fleshed 'Maradol', 'Sunrise', and 'Caribbean Red' papayas often sold in U.S. markets are commonly grown in Mexico and Belize.
Genetically engineered cultivars
was the first transgenic fruit tree
to have its genome
In response to the papaya ringspot virus
outbreak in Hawaii, in 1998, genetically altered papaya were approved and brought to market (including 'SunUp' and 'Rainbow' varieties.) Varieties resistant to PRV have some DNA of this virus incorporated into the DNA of the plant.
As of 2010, 80% of Hawaiian papaya plants were genetically modified. The modifications were made by University of Hawaii
scientists, who made the modified seeds available to farmers without charge.
In 2018, global production of papayas was 13.3 million tonnes
, led by India with 45% of the world total (table). Global papaya production grew significantly over the early 21st century, mainly as a result of increased production in India and demand by the United States.
Diseases and pests
Papaya ringspot virus
is a well-known virus within plants in Florida.
The first signs of the virus are yellowing and vein-clearing of younger leaves, as well as mottling yellow leaves. Infected leaves may obtain blisters, roughen, or narrow, with blades sticking upwards from the middle of the leaves. The petioles and stems may develop dark green greasy streaks and in time become shorter. The ringspots are circular, C-shaped markings that are a darker green than the fruit. In the later stages of the virus, the markings may become gray and crusty. Viral infections impact growth and reduce the fruit's quality. One of the biggest effects that viral infections have on papaya is the taste. As of 2010, the only way to protect papaya from this virus is genetic modification
The papaya mosaic virus
destroys the plant until only a small tuft of leaves are left. The virus affects both the leaves of the plant and the fruit. Leaves show thin, irregular, dark-green lines around the borders and clear areas around the veins. The more severely affected leaves are irregular and linear in shape. The virus can infect the fruit at any stage of its maturity. Fruits as young as two weeks old have been spotted with dark-green ringspots about 1 inch (25 mm) in diameter. Rings on the fruit are most likely seen on either the stem end or the blossom end. In the early stages of the ringspots, the rings tend to be many closed circles, but as the disease develops, the rings increase in diameter consisting of one large ring. The difference between the ringspot and the mosaic viruses is the ripe fruit in the ringspot has mottling of colors and mosaic does not.
The fungus anthracnose
is known to specifically attack papaya, especially the mature fruits. The disease starts out small with very few signs, such as water-soaked spots on ripening fruits. The spots become sunken, turn brown or black, and may get bigger. In some of the older spots, the fungus may produce pink spores. The fruit ends up being soft and having an off flavor because the fungus grows into the fruit.
The fungus powdery mildew
occurs as a superficial white presence on the surface of the leaf in which it is easily recognized. Tiny, light yellow spots begin on the lower surfaces of the leaf as the disease starts to make its way. The spots enlarge and white powdery growth appears on the leaves. The infection usually appears at the upper leaf surface as white fungal growth. Powdery mildew is not as severe as other diseases.
The fungus phytophthora blight
causes damping-off, root rot
, stem rot, stem girdling, and fruit rot. Damping-off happens in young plants by wilting and death. The spots on established plants start out as white, water-soaked lesions at the fruit and branch scars. These spots enlarge and eventually cause death. The most dangerous feature of the disease is the infection of the fruit, which may be toxic to consumers.
The roots can also be severely and rapidly infected, causing the plant to brown and wilt away, collapsing within days.
The papaya fruit fly
lays its eggs inside of the fruit, possibly up to 100 or more eggs.
The eggs usually hatch within 12 days when they begin to feed on seeds and interior parts of the fruit. When the larvae
mature usually 16 days after being hatched, they eat their way out of the fruit, drop to the ground, and pupate
in the soil to emerge within one to two weeks later as mature flies. The infected papaya turns yellow and drops to the ground after infestation by the papaya fruit fly.
The two-spotted spider mite
is a 0.5-mm-long brown or orange-red or a green, greenish-yellow translucent oval pest. They all have needle-like piercing-sucking mouthparts and feed by piercing the plant tissue with their mouthparts, usually on the underside of the plant. The spider mites spin fine threads of webbing on the host plant, and when they remove the sap, the mesophyll tissue collapses and a small chlorotic spot forms at the feeding sites. The leaves of the papaya fruit turn yellow, gray, or bronze. If the spider mites are not controlled, they can cause the death of the fruit.
The papaya whitefly lays yellow, oval eggs that appear dusted on the undersides of the leaves. They eat papaya leaves, therefore damaging the fruit. There, the eggs developed into flies in three stages called instars. The first instar has well-developed legs and is the only mobile immature life stage. The crawlers insert their mouthparts in the lower surfaces of the leaf when they find it suitable and usually do not move again in this stage. The next instars are flattened, oval, and scale-like. In the final stage, the pupal whiteflies are more convex, with large, conspicuously red eyes.
Papayas are one of the most common hosts for fruit flies like A. suspensa
, which lay their eggs in overripe or spoiled papayas. The larvae of these flies then consume the fruit to gain nutrients until they can proceed into the pupal stage. This parasitism has led to extensive economic costs for nations in Central America.
Male papaya flowers
The unripe green fruit can be eaten cooked
, but not raw due to its poisonous latex
content. The ripe fruit of the papaya is usually eaten raw, without skin or seeds
The black seeds of the papaya are edible and have a sharp, spicy taste.
Green papaya is used in Southeast Asian
cooking, both raw and cooked. In some parts of Asia, the young leaves of the papaya are steamed
and eaten like spinach
Papayas became a part of Filipino cuisine
after being introduced to the islands via the Manila galleons
Unripe or nearly ripe papayas (with orange flesh but still hard and green) are julienned
and are commonly pickled into atchara
, which is ubiquitous as a side dish
to salty dishes.
Nearly ripe papayas can also be eaten fresh as ensaladang papaya
(papaya salad) or cubed, and eaten dipped in vinegar or salt. Green papaya is also a common ingredient or filling in various savory dishes such as okoy
, and empanada
, especially in the cuisines of northern Luzon
In Brazil, the unripe fruits are often used to make sweets or preserves
Both green papaya fruit and its latex
are rich in papain
used for tenderizing meat
and other proteins, as practiced currently by indigenous
Americans, people of the Caribbean region, and the Philippines
It is now included as a component in some powdered meat tenderizers.
Papaya is not suitable for gelatin-based desserts because the enzymatic properties of papain prevent gelatin
Allergies and side effects
Papaya releases a latex fluid when not ripe, possibly causing irritation and an allergic reaction in some people. Because the enzyme papain acts as an allergen
in sensitive individuals,
meat that has been tenderized with it may induce an allergic reaction
