Passiflora edulis is a vine species of passion flower that is native to Brazil, Paraguay and northern Argentina. Its common names include passion fruit (US), passionfruit (UK and Commonwealth), and purple granadilla (South Africa).

It is cultivated commercially in tropical and subtropical areas for its sweet, seedy fruit and is widely grown in several countries of South America, Central America, the Caribbean, Africa, Southern Asia, Israel, Australia, Hawaii (Lilikoʻi)[1] and United States.

The passion fruit is round to oval, either yellow or dark purple at maturity, with a soft to firm, juicy interior filled with numerous seeds.[2][3] The fruit is both eaten and juiced; passion fruit juice is often added to other fruit juices to enhance aroma.[4]

Varieties[edit]

Several distinct varieties of passion fruit with clearly differing exterior appearances exist.[2] The bright yellow flavicarpa variety, also known as the Golden Passion Fruit, can grow up to the size of a grapefruit, has a smooth, glossy, light and airy rind, and has been used as a rootstock for the Purple Passion Fruit in Australia.[2] The dark purple edulis variety is smaller than a lemon, though it is less acidic than the yellow passion fruit, and has a richer aroma and flavour.

Several varieties of passion fruit are rich in polyphenol content,[5][6] and yellow [Note 1] varieties of the fruit were found to contain prunasin and other cyanogenic glycosides in the peel and juice.[7]

Uses[edit]

Across the world, passion fruit has a variety of uses related to its appealing taste as a whole fruit and juice.[2]

Passion fruit oil[edit]

Passion fruit oil is composed mainly of linoleic acid (77%) with smaller amounts of oleic acid (15%) and palmitic acid (10%).[citation needed] It has varied applications in cosmetics manufacturing and for uses as a human or animal food.[citation needed]

Fresh passion fruit contains provitamin A beta carotene, vitamin C (36%), dietary fiber (42%) and iron (12%) in significant quantities as percent of the Daily Value; the vitamin A content converted from provitamin A sources is 25%.[10] Passion fruit juice is a good source of potassium, possibly making the fruit relevant as a nutrient source for lowering risk of high blood pressure.[11] Preliminary research indicated that consuming passion fruit peel may relieve asthma symptoms.[12] One report showed that the fruit pericarp contains lycopene.[13]

Culture[edit]

Passion fruit flower - the national flower of Paraguay

The passion fruit is so called because it is one of the many species of passion flower, leading to the English translation of the Latin genus name, Passiflora.[2] The name was given by Spanish missionaries to South America as an expository aid while trying to convert the indigenous inhabitants to Christianity.

The flower of the passion fruit is the national flower of Paraguay.[14]

Diseases[edit]

Viruses[edit]

Passion fruit woodiness virus is one of the most well known viruses to the passion fruit. It belongs to the Potyvirus group and can attack a plant at any age from nursery to mature plants. Some features include yellow leaves that display distortion in the leaf length and shape. As well as affecting the leaf, this virus influences fruit shape and size. Affected fruits become stone-like and under-sized, with many fruits becoming scabbed and cracked. The virus is spread through sap sucking insects such as aphids and mites. Woodiness can also spread through vegetation propagation such as infected scions or contaminated tools. There is no chemical control for this virus once the plant is infected but the use of clean planting material can reduce its dissemination.[15]

One of the most serious viruses pertaining to vegetation is the Cucumber mosaic virus. In the passion fruit, this virus appears with yellow mottling on leaves starting at random points on the vine and diminishing in intensity towards the tip. Expanding leaves typically become twisted, curl downward, and develop a "shoestring" appearance as a result of a restriction of the leaf surface. It is mobile and can spread easily through interactions with other plants such as brushing between leaves. This virus is naturally transmitted through aphids and can also be transmitted mechanically through seedlings. Varietal resistance is the primary management tool, and eliminating weeds and infected perennial ornamentals that may harbor the virus is critical. Once the plant has been infected, there is no possible management of control for the virus.[15]

Phytoplasma[edit]

Overshooting is the term used when Phytoplasma, a specialized bacterium, attacks the phloem of a plant. Phytoplasma infection is characterized by chlorotic small leaves, shortening of internodes, excessive lateral shoots and abnormal flowers. Although there have been reports of this disease within the passion fruit plant,[16] many infected plants are affected without visible signs of disease. Although Phytoplasma can be spread through grafting, it can be inhibited by periodic inspection of plant nurseries and areas that have had past infections.[16] Overshooting responds to treatment with tetracycline, a common broad-spectrum antibiotic.

Bacteria[edit]

Bacterial leaf spot, which causes vein clearing, forms bright yellow colonies causing infection and leaf wilt and, eventually, deterioration of fruit pulp, especially of young fruits. Under favorable conditions for the bacteria, infection occurs through natural openings or wounds from other pathogens that affect leaf inter-cellular spaces. Fertilizers or a copper chloride and mancozeb mixture can control the intensity of the disease, but are not a cure.[17]

The bacterial grease-spot of the passion fruit is caused by Pseudomonas syringae.[18] It appears with olive green to brown greasy looking spots or brown sunken circular lesions. On a later stage, a hard crust can cover the lesions showing a chlorotic halo. Affecting mainly the stomata, the grease-spot thrives in high temperatures and relative humidity. To avoid infection, measures that may be adopted include planting seeds from healthy plants and using existing healthy areas. Fungicide controls can aid in preventing further infection.[18]

Fungal diseases[edit]

Collar rot disease is caused from the fungus Fusarium solani. It is characterized by necrotic lesions at the collar region, browning of the stem at soil level, and dark discoloration of the stem. The rotting stem interferes with food and water transport within the plant, leading to withering of the plant until death. Infection occurs mostly through contaminated soil and infected plants which cause the plants to survive for only a few weeks. There are no chemical controls. Management includes planting seedlings in unaffected areas and using clean tools.[17]

The fungus called fusarium wilt commonly occurs in adult plants and is caused by Fusarium oxysporum. The pathogen has ability to survive for long periods, penetrating roots, invading the xylem and preventing the transport of water and nutrients to other organs of the plant. Once infected, this disease causes leaves to yellow and browning of the vascular system until it wilts and dies. It occurs in any type of soil infecting all plants. Management of crops include planting clean seedlings, uprooting and burning infected plants, and using sterilized tools.[18]

The anthracnose, a canker caused by Colletotrichum gloeosporiodes, is a pathogen of the passion fruit creating dark and sunken lesions of the trunk.[19] By attacking mature passion fruit trees, these lesions cause intense defoliation and fruit rot. Many leaves die due to the foliar lesions and the skin of fruits becomes papery. Under warm and humid conditions, this disease can worsen, causing red and orange spores eventually killing the plant. Infection is carried out through the residues of the passion flower, infected seeds, seedlings, and cuttings. Managing this disease involves a combination of using pathogen-free seedlings, eliminating infected areas, and improving ventilation and light conditions. Copper-based fungicides on injured areas can prevent the spread of disease.[19]
