Estudo sobre o enraizamento de perfilhos de pupunheira utilizando acido indol 3-butirico por via seca, em quatro tipo de contracoes e tres tamanhos de perfilhos, em Manaus-AM. A coleta aleatoria foi pela realizada pela prte da manha em varias plantas. Apos a aplicacao do acido, os perfilhos foram plantados em sacos de plastico transparentes, com aproximadamente 10cm de sua base introduzida no substrato de terrico de mata mais areia lavada (80% e 20%, respectivamente). Nas condicoes do presente experimento, concluiu-se que: - todas as concentracoes de AIB estudadas tiveram efeito negativo no enraizamento da pupunheira; e - os tamanhos de perfilhos que menos enraizaram foram entre 20cm e 50cm. Devido aos resultados negativos, e' sugerida a continuacao desta pesquisa com tecnicas mais aperfeicoados, tais como utilizacao de outros substratos, reducao foliar para reduzir a transpiracao; corte dos perfilhos, deixando-os no mesmo local, com amontoa ao seu redor ate ao enraizamento, concentracoes menores do acido indol 3-butirico e utilizacao de outros reguladores de crescimento |

Banana production is seriously threatened by Fusarium wilt (FW), a disease caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc). In the mid-twentieth century FW, also known as ?Panama disease?, wiped out the Gros Michel banana industry in Central America. The devastation caused by Foc race 1 was mitigated by a shift to resistant Cavendish cultivars, which are currently the source of 99% of banana exports. However, a new strain of Foc, the tropical race 4 (TR4), attacks Cavendish clones and a diverse range of other banana varieties. Foc TR4 has been restricted to East and parts of Southeast Asia for more than 20 years, but since 2010 the disease has spread westward into five additional countries in Southeast and South Asia (Vietnam, Laos, Myanmar, India, and Pakistan) and at the transcontinental level into the Middle East (Oman, Jordan, Lebanon, and Israel) and Africa (Mozambique). The spread of Foc TR4 is of great concern due to the limited knowledge about key aspects of disease epidemiology and the lack of effective management models, including resistant varieties and soilmanagement approaches. In this reviewwe summarize the current knowledge on the epidemiology of FWof banana, highlighting knowledge gaps in pathogen survival and dispersal, factors driving disease intensity, soil and plant microbiome and the dynamics of the disease. Comparisons with FW in other crops were also made to indicate possible differences and commonalities. Our current understanding of the role of main biotic and abiotic factors on disease intensity is reviewed, highlighting research needs and futures directions. Finally, a set of practices and their impact on disease intensity are discussed and proposed as an integrative management approach that could eventually be used by a range of users, including plant protection organizations, researchers, extension workers and growers.
