characteristic of papaya

It was named 'Solo' in 1919 and by 1936 was the only commercial papaya in the islands. Green papaya is commonly canned in sugar sirup in Puerto Rico for local consumption and for export. It is transmitted by the same vectors. Fruits borne 2 or 3 months after the first symptoms will have a disagreeable, bitter flavor. The Instituto Colombiano Agropecuario, at Palmira, Colombia, began a papaya breeding program in 1963 by bringing together Colombian-grown cultivars–'Campo Grande', 'Tocaimera', 'Zapote', 'Solo',–with some from Brazil–'Betty', 'Bettina' and '43-A-3'–South Africa–'Hortus Gold'–and Puerto Rico, and representatives of related species: C. candamarcensis Hook. The wonder fruit is rich in several nutrients like Vitamin C which can keep you free from stress. Fungicidal sprays and removal of diseased plants and fruits will reduce the incidence. Though the exact area of origin is unknown, the papaya is believed native to tropical America, perhaps in southern Mexico and neighboring Central America. When these reach 8 in to 1 ft (20-30 cm) in height, all are cut off except the most vigorous one which replaces the original top. The first two of these species were not suited to conditions at Palmira. Thereafter, natural enemies seriously reduced the plantings. Arthritis can be a really debilitating disease and people who have it may find their quality of life reduced significantly. In 1955 a 'Dwarf Solo' (a back-cross of Florida's 'Betty' and 'Solo') was introduced to aid harvesting, and this became the leading commercial papaya on the island of Oahu. Anthracnose, which usually attacks the ripe fruits and is caused by the fungus Colletotrichum gloeosporioides, was formerly the most important papaya disease in Hawaii, Mexico and India, but it is controllable by spraying every 10 days, or every week in hot, humid seasons, and hotwater treatment of harvested fruits. Its small black seeds are edible, although rarely used, t. Brief exposure to 32º F (-0.56º C) is damaging; prolonged cold without overhead sprinkling will kill the plants. Semi-wild (naturalized) plants bear miniature fruits 1 to 6 in (2.5-15 cm) long. Spraying or dusting should begin when many adults are noticed. In Florida, virus diseases were recognized as the greatest threat to the papaya industry in the early 1950's. Fruits can be held at 85º F (29.64º C) and high atmospheric humidity for 48 hours to enhance coloring before packing. In today’s times, it is near impossible to avoid eating foods that are bad for your digestive system. This is the lowest temperature at which ripe papayas can be held without chilling injury. Planted 1 ft (30 cm) deep in the rainy season, they began fruiting in a few months very close to the ground. Bunchy top can be distinguished from boron deficiency by the fact that the tops of affected plants do not ooze latex when pricked. The fruits may be immersed in boiling 10% lye solution for 6 minutes, in a 15% solution for 4 minutes, or a 20% solution for 3 minutes. The fresh crushed seeds yield the aglycone of glucotropaeolin benzyl isothiocyanate (BITC) which is bacteriostatic, bactericidal and fungicidal. Mechanical cultivation between rows is apt to disturb the shallow roots. Both forms occur in some northcoast plantations. For the local market, in winter months, papayas may be allowed to color fairly well before picking, but for local market in summer and for shipment, only the first indication of yellow is permissible. The babaco, or chamburo (C. pentagona Heilborn), is commonly cultivated in mountain valleys of Ecuador. Picking starts when the plants are 11 months of age and continues for 48 months when the trees are 25 ft (7.5 m) high, too tall for further usefulness. Those held for 12 days will be saleable thereafter for 5 days. In 1965, a program of papaya improvement was undertaken in Trinidad and Tobago utilizing promising selections from local types, including 'Santa Cruz Grant', a vigorous plant mainly bisexual (having both male and female flowers), very large fruits weighing 10 to 15 lbs (4.5-6.8 kg), with firm, yellow flesh of agreeable flavor. To shorten a papaya tree simply cut the top inch off of your tree. 1' is valued for eating fresh; 'Co. It is used to clarify beer, also to treat wool and silk before dyeing, to de-hair hides before tanning, and it serves as an adjunct in rubber manufacturing. In El Salvador, after the 3rd year of bearing, the main stem is cut off about 3 ft (1 m) from the ground at the beginning of winter and is covered with a plastic bag to protect it from rain and subsequent rotting. The roots usually extend out beyond the leaves and it is advisable to spread fertilizer over the entire root area. Because of its papain content, a piece of green papaya can be rubbed on a portion of tough meat to tenderize it. Carotenoid content of papaya (13.8 mg/100 g dry pulp) is low compared to mango, carrot and tomato. Studies in Hawaii have shown that papaya flavor is at its peak when the skin is 80% colored. White seeds yielded 16.1% and black seeds 26.8% and it was suggested that the oil might have edible and industrial uses. Because of the need to expedite growth and production before the onslaught of diseases, Puerto Rican agronomists recommend treating the predominantly clay soil with a nematicide before planting, giving each plant 4 oz (113 g) of 15-15-15 fertilizer at the end of the first week, and each month thereafter increasing the dose by 1 oz (28 g) until the beginning of flowering, then applying .227 g per plant as a final treatment. Wiki User Answered . Sometimes a chunk of green papaya is cooked with meat for the same purpose. Mature leaves are bitter and must be boiled with a change of water to eliminate much of the bitterness. 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). The latex coagulates quickly and, for best results, is spread on fabric and oven-dried at a low temperature, then ground to powder and packed in tins.

Two forms of mosaic virus are reported in Puerto Rico: the long-known "southern coast papaya mosaic virus", the symptoms of which include extreme leaf deformation, and the relatively recent "Isabela mosaic virus" on the northern coast which is similar but without leaf distortion. Plant refuse from previous plantings should never be incorporated into the soil. The Regional Research Station at Pusa has introduced some promising selections: 'Pusa Delkious' ('Pusa 1-15')–medium size; flesh deep-orange, of excellent flavor; female and hermaphrodite plants; high-yielding. Papaya ringspot virus, prevalent in Florida, the Dominican Republic and Venezuela, is occasionally serious in the Waianae area on the dry leeward side of Oahu. These are layered and removed and the trunk cut off above the originally retained lowest sprout which is then allowed to grow as the main stem. Papaya leaves contain the bitter alkaloids, carpaine and pseudocarpaine, which act on the heart and respiration like digitalis, but are destroyed by heat. In India, papaya breeding and selection work has been carried on for over 30 years beginning with 100 introduced strains and 16 local variations. Australian growers are hopeful that the papaya can be bred for low nitrate uptake. High nitrate content in canned papaya (as with several common vegetables) removes the tin from the can. 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.
