Its white flowers (15-25 mm across) have five petals and numerous stamens. 1989. ex DC.) Ocorre naturalmente da Bahia ao Rio Grande do Sul, na Mata Altlântica. [10] Though native to Brazil, it is now distributed throughout many tropical regions. O araçazeiro, cujo fruto é o araçá, é uma árvore ou arvoreta, de copa esparsa, muitas vezes com porte arbustivo, alcançando de 1 a 9 metros de altura.

[7][10], P. cattleyanum does not dominate plant communities in its native range. Suitable pH: acid, neutral and basic (alkaline) soils. Smith, C. W. 1985. Thus, some control efforts involve removal and control of invasive fauna. Huenneke, L.F. and P. M. Vitousek. The leaves are dark green, opposite, elliptic to oblong and up to 8 cm long. US Forest Service. [10] However, results from such efforts are often unsuccessful due to the lack of dependence upon the animals for dispersal, as germination occurs under a wide variety of conditions. [11], The whole fruit can be eaten as both the thin skin and juicy interior are soft and tasty. [9] P. cattleyanum has smooth, grey to reddish-brown bark, with oval to elliptical leaves that grow to 4.5 cm in length. K. McCook-Russella, M. Nairb, P. Faceya, C. Bowen-Forbesa. Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. The whitish flesh is very juicy and has a strawberry flavour which in some varieties can have a spicy taste. Wessels, Frank J., James P. Cuda, M. Tracy Johnson and José Henrique Pedrosa-Macedo. We recognise the support from the National Museums of Kenya, Tropical Pesticides Research Institute (TPRI) - Tanzania and Makerere University, Uganda. A complete guide to declared weeds and invaders in South Africa. Seu tronco é tortuoso e apresenta casca lisa, escamosa, na cor cinza a marrom avermelhada, com ramos pubescentes quando jovens. Se le conoce como guayabo peruano, arazá rojo, guayabita del Petú o güisaro, es natural de América del Sur, especialmente de Perú. Its bark is grey to reddish-brown and peels readily. In tropical climates, P. cattleianum is most often found growing at higher elevations, where the mean temperature is relatively cool. It is considered to be the worst invasive plant species in several islands in the Indian Ocean. [21] Its ability to thrive in a variety of different habitats under many different ecological conditions[16] threatens native flora of many different habitat types. Small plants can be removed by hand. Its fleshy fruit (2-3 cm across) turn purplish-red in colour when mature and are crowned with the some of the old flower parts. Psidium cattleyanum (World Plants : Psidium cattleianum),[2][3] commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. The species is named in honour of English horticulturist William Cattley. [12] This management strategy, known as the “special ecological areas,” is one of the strongest ways of controlling plant species over time. [8], Cattley guava is sporadically naturalised in coastal areas of Queensland and northern New South Wales. Although P. cattleyanum has select economic uses,[2][5][6] it is considered the most invasive plant in Hawaii. [23] However, some insects cannot be used due to the potential for certain species to attack more than P. Guajava cattleyana (Sabine) Kuntze Guajava obovata (Mart. Huenneke, L. (1990). Hawaii, Honolulu. Não confunda com o araçá-boi (Eugenia stipitata), também conhecido como araçá-do-sertão ou araçá-mark. These flowers are borne singly in the leaf upper forks. 12, 300pp. Psidium cattleianum (Guayabo fresa) Ugni molinae 'flambeau' Ugni molinae (Murtilla) FRUTOS DEL BOSQUE. [2][12] However, products made from P. cattleyanum are not commercially available because of a lack of market and the heavy presence of fruit flies. Global Invasive Species Database online data sheet. State of Hawaii. P. cattleianum is naturalized in many tropical and subtropical countries after introduction as an ornamental or a fruit tree. [9], P. cattleyanum reproduces through setting seed and through cloning. [16], P. cattleyanum acts as an invasive by creating dense thickets that crowd out sunlight, limiting the potential for other plant species to coexist. Como ocurre en muchos frutales tropicales y subtropicales las hojas del Psidium cattleianum, para protegerse del frio y de las peligrosas heladas del invierno mediterráneo, sintetizan antocianos y se tiñen de rojo-morado al bajar la temperatura en otoño. This renders the fruits inedible soon after they are picked. Psidium obovatum Mart. [16] Additionally, P. cattleyanum is both very shade-tolerant[14] and able to withstand soils with a moderate to high pH level. However, these uses cannot compensate for this plant's overall negative impacts. Univ. [14] Its invasive quality may be explained by a high amount of genetic variation, as variants of different fruit colors cluster at different elevations. If prevention is no longer possible, it is best to treat the weed infestations when they are small to prevent them from establishing (early detection and rapid response). It is hardy to zone (UK) 10 and is frost tender. These species can be distinguished by the following differences: The fruit of Psidium cattleianum is edible and can be eaten raw or processed into jams and other products. Hawaii's terrestrial ecosystems: preservation and management. Psidium cattleianum may be confused with Psidium guajava (guava) and Psidium guineense (Brazilian guava). Plant Protection Research Institute Handbook No. Common Name: Strawberry Guava. & A.Ludw. Bark Photograph by: Starr, F. & K. Image credit to Australian National Botanic Gardens. Biocontrol of Strawberry Guava by its Natural Control Agent for Preservation of Native Forests in the Hawaiian Islands. The yellow form tends to be a bit less hardy and therefore is found at slightly lower elevations. La planta de guayaba pertenece a la familia de las Myrtaceae, son una agrupación de árboles que crecen en el hemisferio sur, comúnmente son cítricos y con un follaje siempre verde. [11] Despite the great threat that P. cattleyanum poses to many tropical ecosystems, some studies indicate that isolated groups can be totally eradicated after three to four years of proper management applications, such as cutting and burning mature individuals and applying herbicide to stumps. 180-250. in C. P. Stone and J. M. Scott (eds.). coriaceum O.Berg Psidium cattleianum var. The best form of invasive species management is prevention. Locations within which Psidium cattleianum is naturalised include Australia, tropical and southern Africa, New Zealand, south-eastern USA and many oceanic islands with warm climates. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. Special ecological areas: an approach to alien plant control in Hawaii Volcanoes National Park. [18], A variety of management strategies have been applied to P. cattleyanum management efforts due to its ubiquity and the various ways it spreads. Pacific Southwest Research Station. The wood is useful for poles. The seeds of which are dispersed by birds and mammals. Its genus name Psidium comes from the Latin psidion, or "armlet. Seedling and clonal recruitment of the invasive tree Psidium cattleianum: Implications for management of native Hawaiian forests. It has invaded humid areas such as rainforests on tropical islands especially in the Pacific and Indian Oceans where it displaces native species and threatens their survival. [10], Preliminary research suggests that P. cattleyanum is allelopathic,[14] as its roots have been found to inhibit the growth of at least two other plant species when soil pH was not a factor.[18]. Strawberry Guava: Not All Green Is Good. Psidium cattleianum de 10 años de edad y 1´5 metros de altura cargado de frutos a principios de octubre. La guayaba es una de las frutas más ricas en vitamina C , ya que algunas variedades poseen cinco veces más que la naranja. Not listed as a noxious weed by the state or governments in Kenya, Tanzania and Uganda. littorale … Psidium cattleianum produces a lot of fruit with each seed containing up to though usually less than 70 seeds. It bears fruit when the plants are between 3 and 6 years old. Its leaves may be brewed for tea. Park Resour. littorale is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava,[2] lemon guava and in Hawaii as waiawī. Psidium ferrugineum C.Presl. Psidium littorale Raddi. It is now highly prevalent in tropical rain forest ecosystems due mainly to accidental transportation and its invasive plant properties. (2012). [21] Additionally, its potential allelopathic qualities[14] further complicate the ability of other plant species to coexist. Guayaba fresa (Psidium cattleianum): fotos e información (identificada) (Leer más...) bueno , tengo un frutal precioso , tiene unos pequeños frutos, son raros, el arbol es precioso y tiene hojas todo el año, las hojas son parecidas ala camelia, siempre cargaditos de frutos , en estos momentos el arbol tiene mucha flor tengo suerte y alguien me dice su nombre y asta pronto Some components of an integrated management approach are introduced below. Its genus name Psidium comes from the Latin psidion, or "armlet." Host specificity of Tectococcus ovatus (Hemiptera: Eriococcidae), a potential biological control agent of the invasive strawberry guava, Psidium cattleyanum (Myrtales: Myrtaceae), in Florida. [11] The Brazilian Scale is a potential biological control agent used in Florida,[22] and Hawaii. The editors are not aware of records of the presence of  P. cattleianum in Kenya and Uganda, though this does not necessarily mean that it is absent from these countries. [19] It is able to propagate quickly due to the spread of its seed, which occurs as its seeds fall and as birds and feral pigs transport fruits,[10] as well as through its root sprouts. Psidium cattleyanum (World Plants : Psidium cattleianum), commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. Natl. This fact sheet is adapted from The Environmental Weeds of Australia by Sheldon Navie and Steve Adkins, Centre for Biological Information Technology, University of Queensland. Psidium cattleianum is invasive in parts of Tanzania (Tropical Biology Association 2010). 33. It can also reshoot from stumps and produce suckers from near the base of the trunk. Consistent follow-up work is required for sustainable management. Psidium cattleianum can form dense thickets that exclude native vegetation and reduce native species regeneration. Sus hoja son elípticas, y sus flores blancas. Growth inhibition from guava root exudates. (2010). The red-fruited variety, P. cattleyanum var. pp. The seeds are small and white in colour. Control is generally best applied to the least infested areas before dense infestations are tackled. leaves, flowers and young fruit (Photo: Rosa Say, CC BY-NC-ND), immature fruit (Photo: John Mauremootoo, CC-BY-NC), mature fruit (Photo: Forest & Kim Starr, CC-BY), infestation, Mauritius (Photo: John Mauremootoo, CC-BY-NC), Psidium cattleianum var.

Research into biological control agents for P. cattleianum is being carried out in Hawaii. [7][8], Psidium cattleyanum is a small, highly-branched tree that reaches a maximum height of 13 meters, although most individuals are between 2 and 4m. The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species. cattleyanum. [25], The Complete Book of Fruit Growing in Australia, Louis Glowinski, ISBN 0 85091 870 7. [12] It works by focusing wood removal, burning, and other management efforts in the designated efforts. [24] The wood of the tree is hard, compact, durable, and resistant, and is used for lathe work, tool handles, charcoal, and firewood. Psidium cattleianum is an evergreen Shrub growing to 6 m (19ft 8in). Psidium cattleianum is a small erect evergreen bush or tree growing to 7.5 m, although often much smaller.

"Strawberry Guava - Psidium cattleianum - Overview - Encyclopedia of Life". Alien weeds and invasive plants. [10], Another management technique is the introduction of insects that act as parasites on the invasive plants. Bark Photograph by: Starr, F. & K. Image credit to Australian National Botanic Gardens. The species is named in honour of English horticulturist William Cattley. It was introduced to many of the areas it now invades due to human usage as a crop for its edible fruit. [15] P. cattleyanum is prevalent in both undisturbed[10] and highly disturbed roadside habitats in its invasive range. Plantas hospederas: Polifago, guayaba (Psidium guajava), arazá (Psidium cattleianum), camelia (Camellia japonica), caquizeiro (Diospyros kaki), níspero del japón (Eriobotrya japonica), pomarrosa (Eugenia jambos) etc. Its flowers grow either individually or in clusters of three, and each flower has five petals. It is also naturalised on Lord Howe Island, Norfolk Island and Christmas Island (Navie 2004; Queensland Herbarium 2008). [12] However, continued follow-up management is necessary indefinitely after a period of high-intensity restoration. Henderson, L. (2001). Contienen más de 130 géneros, entre ellos las psidium, donde se encuentra: la psidium guajava (guayaba común), la psidium cattleianum (árbol de guayaba fresa) y otras especies como el árbol de guayaba rosa. The skin is often removed for a sweeter flavour. Imagen – Flickr/Candise Sorensen. 1983. Cultivo transitorio de arveja (Pisum sativum) intercalado con guayaba peruana y pino romerón banco de germoplasma ex situ: es una co- lección genética de poblaciones naturales de una especie forestal que se establece en un área geográfica que puede corresponder a la zona de distribución natural de la especie o a una que presente … Studies Unit, University of Hawaii Press. [7] It tends to form dense, monotypic stands which prevent regrowth of native species, and is very difficult to eradicate; it also provides refuge for fruit flies which cause extensive agricultural damage. Additionally, feral pigs may ingest the fruits, whose seeds reach the soil in the scat of the feral pigs. BioNET-EAFRINET Regional Coordinator:, Introduced, naturalised or invasive in East Africa, Existing plants must be prevented from spreading). Univ. Sem, G. S. 1984. [12] Additionally, its seeds have many health benefits, including antioxidant, anti-inflammatory, and antimicrobial properties in addition to a high amount of Vitamin C.[9][13], P. cattleyanum occurs primarily in mesic tropical rainforest environments[10] at an elevation of up to 1300m, but is found primarily below 800m. The plant is indispensable for mixed planting in reforestation of reclaimed and protected areas in Brazil. Most of the proposed insects infect the tree with bud or leaf galls, effectively preventing fruit growth or photosynthesis. "[4] The red-fruited variety, P. cattleyanum var. Some varieties have a yellow skin. Agricultural areas, coastland, natural forests, planted forests, range/grasslands, riparian zones (banks of watercourses), ruderal/disturbed, scrub/shrublands, urban areas, wetlands (Henderson 2001). Araçá-rosa (Psidium cattleianum) — nomes populares: araçá-rosa, araçá-amarelo, araçá-vermelho, araçá-de-comer, araçá-comum, araçá-de-coroa, araçá-da-praia, araçá-do-campo, araçazeiro, araçaeiro ou, simplesmente, araçá. Lowe S., Browne M., Boudjelas S., De Poorter M. (2000). 584. As an invasive species, P. cattleyanum is sometimes erroneously called Chinese guava. [11] This biological control approach is used because certain insects cause damage to P. cattleyanum in a way that either prevents the tree from reproducing or kills them outright. No suele superar los 3 metros de altura, pero en ocasiones puede crecer hasta convertirse en un árbol de hasta 10 metros. Psidium cattleianum Name Synonyms Episyzygium oahuense Suess. Larger plants can be uprooted but it is labour intensive and the plant can resprout if root fragments are left in the ground. [16], P. cattleyanum is often associated with invasive feral pigs[10][15] The two species are often found near each other, most likely because feral pigs aid in the spread of P. cattleyanum. Various chemicals can be used to control Psidium cattleianum through basal bark (painting herbicide onto the bark) and cut stump applications. (2016). The yellow variety bears even more heavily than the red and generally has larger fruit. [20], P. cattleyanum grows effectively in undisturbed areas,[10] complicating restoration efforts in sensitive habitats. Psidium variabile O.Berg. Brown, R. L., C. S. Tang, and R. K. Nishimoto. (1999). Seedling and clonal recruitment of the invasive tree Psidium cattleianum: implications for management of native Hawaiian forests. [2] The yellow-fruited variety, P. cattleyanum var. Strawberry Guava (Psidium cattleianum) – Prospects for Biological Control. [6][11], P. cattleyanum has modest economic impacts in Hawaii due to its edible fruits and beads that are made by tying individual fruits together. PPR, ARC South Africa. It is in leaf all year, in flower in May. The Psidium cattleianum is now a weed in many parts of the tropics where it has quickly adapted to a variety of climates (Henderson 2001). [6] But, it is invasive due to its robust tolerance to many different environments. Tropical Biology Association (2010). [11] For example, Diasineura gigantea caused bud galls that inhibited shoot growth. When using any herbicide always read the label first and follow all instructions and safety requirements. Hawaii Coop. Its ubiquity in damaged ecosystems further muddles management due to its high dispersal from these less-sensitive habitats to more fragile habitats. Psidium cattleianum (tree, shrub). This fruit has thin skin that ranges from yellow to a dark red or purple, is ovular in shape, and grows to around 4 cm in length. [14] Its native range is restricted to the Amazonian Basin in Brazil, but it has established in many other tropical areas of similar characteristics. [17] It is also capable of withstanding heavy leaf litter and responding to bending or breaking of its branches by generating vigorous shoots. [6][8] It was introduced in Hawaii as early as 1825 to create an agricultural market for its fruits, but it has yet to be a commercially viable product. [11] Once such species, the sawfly (Haplostegus epimelas), attacked commercially produced guava plants in addition to invasive P. lucidum. Department of Land and Natural Resources, 54. Psidium cattleianum. Eugenia ferruginea Sieber Eugenia ferruginea Sieber ex C.Presl Eugenia oxygona Koidz. This activity was undertaken as part of the BioNET-EAFRINET UVIMA Project (Taxonomy for Development in East Africa). It has been nominated as among 100 of the "World's Worst" invaders by the IUCN Invasive Species Specialist Group and it has been listed as an invader in South Africa as a Category 3 invader in South Africa (no further planting is allowed - except with special permission - nor is trade in propagative material. Impact of alien plants on Hawaii's native biota. Locations within which Psidium cattleianum is naturalised include Australia, tropicaland southern Africa, New Zealand, south-eastern USA and many oceanic islands with warm climates. Native to South America (eastern Brazil and north-eastern Uruguay). Controlling the weed before it seeds will reduce future problems. OTROS NOMBRES: Arazá amarillo. Arbusto de Psidium cattleianum Figura 27. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. Nutritional and nutraceutical comparison of Jamaican Psidium cattleianum (strawberry guava) and Psidium guajava (common guava) fruits. GISD (2010). If in doubt consult an expert. The pigs disturb habitats by digging in the soil, making it easier for P. cattleyanum seeds to reach the soil. Clonally produced suckers tend to have a greater leaf area. 2007. 84 pp. Eugenia pseudovenosa H.Perrier Eugenia urceolata Cordem. ex DC. Accessed March 2011.
