Solanum torvum, also known as pendejera, turkey berry, devil's fig, pea eggplant, platebrush or susumber, [2] is a bushy, erect and spiny perennial plant used horticulturally as a rootstock for eggplant. Grafted plants are very vigorous and tolerate diseases affecting the root system, thus allowing the crop to continue for a second year.
The plant is usually 2 or 3 m in height and 2 cm in basal diameter, but may reach 5m in height and 8 cm in basal diameter. The shrub usually has a single stem at ground level, but it may branch on the lower stem. The stem bark is gray and nearly smooth with raised lenticels. The inner bark has a green layer over an ivory color (Little and others 1974). The plants examined by the author [ specify ], growing on firm soil, had weak taproots and well-developed laterals. The roots are white. Foliage is confined to the growing twigs.
The twigs are gray-green and covered with star-shaped hairs. The spines are short and slightly curved and vary from thick throughout the plant, including the leaf midrib, to entirely absent. The leaves are opposite or one per node, broadly ovate with the border entire or deeply lobed. The petioles are 1 to 6 cm long and the blades are 7 to 23 by 5 to 18 cm and covered with short hairs. The flowers are white, tubular with 5 pointed lobes, and grouped in corymbiform cymes. They are shed soon after opening.
The fruits are berries that grow in clusters of tiny green spheres (ca. 1 cm in diameter) that look like green peas. They become yellow when fully ripe. They are thin-fleshed and contain numerous flat, round, brown seeds (Howard 1989, Liogier 1995, Little and others 1974).
Flowering and fruiting is continuous after the shrubs reach about 1 to 1.5 m in height. Ripe fruits collected in Puerto Rico averaged 1.308 + 0.052 g. Air dry seeds from these fruits weighed an average of 0.00935 g or 1,070,000 seeds/kg. These seeds were sown on commercial potting mix and 60 percent germinated between 13 and 106 days following sowing. The seedlings are common in recently disturbed ground. Frugivorous birds eat the fruits and spread the seeds (Pacific Island Ecosystems at Risk 2001). Turkey berry can be propagated vegetatively by placing branch cuttings, with or without leaves, in a mist chamber for one month (Badola and others 1993).
Turkey berry grows about 0.75 to 1.5 m in height per year. The species is not long-lived; most plants live about 2 years. Physical control of the shrub may be done by grubbing out the plants; lopping will not kill them. They can be killed by translocated herbicides applied to the leaves or the cut stumps (Pacific Island Ecosystems at Risk 2001).
Several other Solanum species have at one time been included in S. torvum as subspecies or varieties: [3]
A number of more or less ambiguous and now-invalid names have been used for S. torvum:
Turkey berry apparently is native from Florida and southern Alabama through the West Indies and from Mexico through Central America and South America through Brazil (Little and others 1974). Because of its rapid spread as a weed in disturbed lands, it is difficult to tell which populations are native and which are introduced. Turkey berry has been introduced and naturalized throughout tropical Africa, Asia, Australia, and the Pacific Islands including Hawaii, Guam, and American Samoa (Pacific Island Ecosystems at Risk 2001). In Jamaica this berry is called susumba, or gully beans, and is usually cooked in a dish along with saltfish and ackee. It is believed to be full of iron (it does have a strong iron like taste when eaten) and is consumed when one is low in iron.
In Puerto Rico, turkey berry grows in upland sites that receive from about 1000 to 4000 mm of annual precipitation. It also grows in riparian zones in drier areas. Turkey berry grows on all types of moist, fertile soil at elevations from near sea level to almost 1,000 m in Puerto Rico (Little and others 1974) and 2,000 m in Papua New Guinea (Pacific Island Ecosystems at Risk 2001). Given an equal start after disturbance, turkey berry quickly overtops most herbs, grasses, and other shrubs. It grows best in full sunlight and does well in light shade or shade for part of the day, but cannot survive under a closed forest canopy. Turkey berry single plants, groups, and thickets are most frequently seen on roadsides, vacant lots, brushy pastures, recently abandoned farmland, landslides, and river banks.
It is considered invasive in New Caledonia, where it was likely introduced in 1900. [4]
Turkey berry contains a number of potentially pharmacologically active chemicals including the sapogenin steroid chlorogenin. [5]
Aqueous extracts of turkey berry are lethal to mice by depressing the number of erythrocytes, leukocytes and platelets in their blood (Tapia and others 1996).
Extracts of the plant are reported to be useful in the treatment of hyperactivity, [6] colds and cough, [7] pimples, skin diseases, and leprosy. [8]
Methyl caffeate, extracted from the fruit of S. torvum, shows an antidiabetic effect in streptozotocin-induced diabetic rats. [9]
Cholinergic poisoning has been reported as a result of the consumption of Solanum torvum berries prepared in Jamaican dishes. [10] [11]
The green fresh fruits are edible and used in Thai cuisine, as an ingredient in certain Thai curries or raw in certain Thai chili pastes ( nam phrik ). [12] [13] They are also used in Lao cuisine (Royal Horticultural Society 2001) and Jamaican cuisine. [14] The fruits are incorporated into soups and sauces in the Côte d'Ivoire (Herzog and Gautier-Béguin 2001).
The fruit is also used in Ghanaian cuisine, in stews such as kontomire stew.
In Tamil Nadu, India, the fruit is consumed directly, or as cooked food. In siddha medicine, one of the traditional medicine systems of India, an extract of this berry is used to improve digestion.
This fruit is reportedly used in Haitian voodoo rituals. [15]
Turkey berry has been grafted with eggplant in an attempt to incorporate favorable genes for resistance to Verticillium wilt into the vegetable. [16]
Eggplant, aubergine, brinjal, or baigan is a plant species in the nightshade family Solanaceae. Solanum melongena is grown worldwide for its edible fruit.
Solanum is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant. It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species. It also contains the so-called horse nettles, as well as numerous plants cultivated for their ornamental flowers and fruit.
Solanum mauritianum is a small tree or shrub native to South America, including Northern Argentina, Southern Brazil, Paraguay and Uruguay. Its common names include earleaf nightshade, woolly nightshade, flannel weed, bugweed, tobacco weed, tobacco bush, wild tobacco and kerosene plant.
Solanum aviculare, commonly called poroporo or pōporo, bumurra (Dharug), kangaroo apple, pam plum (Australia), or New Zealand nightshade, is a soft-wooded shrub native to New Zealand and the east coast of Australia.
Solanum pseudocapsicum is a nightshade species with mildly poisonous fruit. It is commonly known as the Jerusalem cherry, Madeira winter cherry, or, ambiguously, "winter cherry". These perennials can be grown decoratively as house plants, but in some areas of South Africa, India, Australia and New Zealand it is regarded as a weed.
Solanum aculeastrum is commonly known as soda apple, sodaapple nightshade, goat apple, poison apple, or more ambiguously as "bitter-apple". It is a poisonous nightshade species from Africa and only distantly related to true apples. The term "soda apple" probably derives from "Sodom apple", modified due to the fruit's detergent properties.
Solanum aethiopicum, the bitter tomato, Ethiopian eggplant, or nakati, is a fruiting plant of the genus Solanum mainly found in Asia and Tropical Africa. It is also known as Ethiopian nightshade, garden eggs, pumpkin-on-a-stick, and mock tomato. It is a popular vegetable in north-east India, and is known as khamen akhaba in Manipuri and samṭawk in Mizo. They are called Titay bii or simply bii in Darjeeling, Sikkim and Nepal, and are relished with meat, particularly pork. These names are a result of its varied morphology, with ripe fruit often looking like a cross between an eggplant and a tomato, which are also from Solanum. In fact, the Ethiopian eggplant was so much confused with the ordinary eggplant that this was considered by some a variety violaceum of S. aethiopicum.
Solanum mammosum, commonly known as nipplefruit, fox head, cow's udder, or apple of Sodom, is an inedible Pan-American tropical fruit. The plant is grown for ornamental purposes, in part because of the distal end of the fruit's resemblance to a human breast, while the proximal end looks like a cow's udder. It is an annual in the family Solanaceae, and part of the genus Solanum, making the plant a relative of the eggplant, tomato, and potato. This poisonous fruit is native to South America, but has been naturalized in Southern Mexico, Greater Antilles, Central America, and the Caribbean. The plant adapts well to most soils, but thrives in moist, loamy soil.
Solanum linnaeanum is a nightshade species known as devil's apple and, in some places where it is introduced, apple of Sodom. The latter name is also used for other nightshades and entirely different plants elsewhere, in particular the poisonous milkweed Calotropis procera.
Solanum elaeagnifolium, the silverleaf nightshade or silver-leaved nightshade, is a species of plant in the nightshade family native to North and South America. It is common in parts of southwestern USA, and sometimes weed of western North America. Other common names include prairie berry, silverleaf nettle, white horsenettle or silver nightshade. In South Africa it is known as silver-leaf bitter-apple or satansbos. More ambiguous names include "bull-nettle", "horsenettle" and the Spanish "trompillo".
Solanum sisymbriifolium is commonly known as vila-vila, sticky nightshade, red buffalo-bur, the fire-and-ice plant, litchi tomato, or Morelle de Balbis.
Solanum capsicoides, the cockroach berry, is a species of flowering plant in the family Solanaceae. It is native to eastern Brazil but naturalized in other tropical regions, where it sometimes becomes an invasive weed.
Solanum paniculatum, commonly known as jurubeba, is a nightshade common in almost all of Brazil. It is used as a medicinal plant and has a bitter taste.
Solanum retroflexum, commonly known as umsobo (isiZulu), wonderberry or sunberry, is a historic heirloom fruiting shrub. Both common names are also used for the European black nightshade in some places, particularly where the latter species has been introduced, so care must be taken to distinguish them. It is sometimes called garden huckleberry, but that properly refers to the species S. scabrum described by Philip Miller.
Solanum lanceolatum, with the common names orangeberry nightshade and lanceleaf nightshade, is a species of nightshade. It is native to regions of South America, including the Cerrado ecoregion of the Tropical and subtropical grasslands, savannas, and shrublands biome, primarily in Brazil.
Solanum candidum is a species of evergreen shrub native to South America and occasionally grown for its edible fruit.
Solanum tampicense, also known as wetland nightshade, aquatic soda apple, and scrambling nightshade, is a perennial in the Solanaceae or Nightshade Family. It can exist as a vine, tree, or shrub and is native to the West Indies and Central America. It is classified as a noxious weed by the United States Department of Agriculture and by several states and is known as an invasive species in the state of Florida.
Solanum macrocarpon otherwise known as the African eggplant : añara), Surinamese eggplant or Vietnamese eggplant is a plant of the family Solanaceae. S. macrocarpon is a tropical perennial plant that is closely related to the eggplant. S. macrocarpon originated from West Africa, but is now widely distributed in Central and East Africa. The plant also grows in the Caribbean, South America, and some parts of Southeast Asia. S. macrocarpon is widely cultivated for its use as a food, its medicinal purposes, and as an ornamental plant.
Solanum pubescens is a wild shrub found in the foot hill areas of southern India. It is very closely related to the Turkey berry. This shrub does not have spines; leaves are smaller in size covered with dense sticky hairs. Flowers are larger, purple to violet, the flowering and fruiting is seasonal in S. pubescens. Flowering will occur from August to December. The fruits are around 1.2 cm diameter and is more bitter. Matured fruits change in color to orange.
Solanum virginianum, also called Surattense nightshade, yellow-fruit nightshade, yellow-berried nightshade, Indian nightshade,Thai green eggplant, or Thai striped eggplant, is a medicinal plant used mostly in India. Some parts of the plant, such as the fruit, are poisonous. Solanum surattense Burm. f. and Solanum xanthocarpum Schrad. and Wendl. are synonyms of Solanum virginianum L..
