25. DetecÃÃo de variantes somaclonais de bananeira âPrata AnÃâ (AAB) micropropagada / Detection of somaclonal variants of micropropagated banana plants âPrata Anaâ (AAB)
The in vitro culture, also known as micropropagation, is a technique used in the attainment of plants with commercial value. This technique is useful in achievement for free pathogenic plants and to maintain the genetic characteristics of the mother plant. However, the micropropagation can lead to phenotypic changes in the plants, known as somaclonal variati

26. Micropropagation of banana: agronomical, physiological and anatomical traits / MICROPROPAGAÃÃO DA BANANEIRA: CARACTERÃSTICAS FITOTÃCNICAS, FISIOLÃGICAS E ANATÃMICAS.
O cultivo de Ãpices caulinares e meristemas utilizando tÃcnicas in vitro constitui a base da propagaÃÃo clonal massal de bananas e plÃtanos. Este trabalho objetivou estudar o desenvolvimento fitotÃcnico e o comportamento fisiolÃgico e anatÃmico em bananeiras micropropagadas. Quatro experimentos foram realizados, os quais avaliaram: 1) a influÃncia d

27. A cultura da bananeira (musa sp.) Como fonte alternativa de nÃctar para a apicultura em perÃodos de escassez de alimento. / The culture of banana (Musa sp.) As an alternative source of nectar for the bee in times of shortage of food.
O experimento foi conduzido na fazenda Frutacor no distrito de Lagoinha, municÃpio de Quixerà - CE, no perÃodo de setembro de 2004 a janeiro de 2005. Objetivou-se avaliar o cultivo irrigado de banana (Musa paradisiaca.), como fonte substituta de alimento para as colÃnias de abelhas (Apis mellifera) em perÃodo de escassez de florada na caatinga. Foram ut

28. Evaluation of the osmotic concentration process to obtain dried banana sticks. / Avaliação do processo de concentração osmotica para obtenção de banana passa.
Brazil is a country with agricultural characteristics and thus the development of the agro-industrial sector is of great socio-economic importance and should be explored so as to avoid food wastage and increase the value of agricultural products and producer profit. Based on the experience of highly successful regions and countries, in industrial transformat

29. Quality evaluation post-harvest of banana "Prata-Anã"associated to packing / Avaliação da qualidade pos-colheita de banana prata anã associada a embalagens
The transformations, occurring in the constitution of banana during the ripening, are factors of great importance to the fresh fruit market and for the industry. Relating to the quality of the fruit, the major problem of Brazilian culture of bananas is the management of the product since the harvest passing by transport, packing, and refrigeration. The other

30. A bananicultura na Ãrea de proteÃÃo ambiental da Serra de Maranguape - CE e suas implicaÃÃes no ambiente fisico,humano e na biodiversidade. / The banana culture in the area of ambient protection of the Serra of Maranguape-Ce and its implicatons in the physical, human environment and in biodiversity
A serra de Maranguape à um maciÃo residual prÃ-litorÃneo, localizado a 25 km de Fortaleza, com altitude mÃxima de 920 m. O tipo de vegetaÃÃo da serra à denominado Floresta SubperenifÃlia Tropical PlÃvio-Nebular e constitui um remanescente de Mata AtlÃntica. Os poucos trabalhos sobre a diversidade biolÃgica da serra, jà realizados, indicam uma bi

31. Luz e sacarose na micropropagaÃÃo da bananeira prata anà :alteraÃÃes morfoanatÃmicas / Light sucrose on Prata anà banana micropropagation: morph-anatomical altered structure
Micropropagation of bananas results in a great quantity of cloned plantlets, produced in a reduced space and in a short period of time. Nevertheless, the anatomical structure of the leaves of the explants formed under in vitro conditions present a series of deficiencies, which result, most of the time, in great volumes of losses due to desiccation, during ac

32. AnÃlise da diversidade genÃtica e patogÃmica de Mycosphaerella fijiensis e Mycosphaerelle musicola no Brasil
Black and yellow Sigatoka diseases, caused by the fungi Mycosphaerella fijiensis and M. musicola, respectively, are responsible for important losses in banana production all over the world. The former disease is distributed over the whole Brazilian territory, with the exception of the Northeast region and the sates of Rio de Janeiro, EspÃrito Santo, GoiÃs

33. Níveis de Putrescina, Poliaminas e Nutrientes Minerais Relacionados a Diferentes Concentrações de Potássio em Bananeira (Musa sp., AAA e AAB) cvs. Nanica e Prata Anã in Vitro / Levels of putrescine, polyamines and mineral nutrients in relation to different potassium concentrations in banana plant (Musa sp., AAA and AAB) cvs. Nanica and Prata anã in vitro condition
Nas abordagens biotecnológicas de propagação de plantas, os meios de cultura devem ter uma composição química adequada à essa finalidade permitindo a otimização da produção. Como a bananeira (Musa sp.) é exigente em potássio, a busca do nível adequado desse macronutriente envolve não somente o comprometimento com o nível dos outros nutrientes

34. Occurrence of free and conjugated 12,13-epoxytrichothecenes and zearalenone in banana fruits infected with Fusarium moniliforme.
Three recognized 12,13-epoxytrichothecene mycotoxins, trichothecolone, diacetoxyscirpenol, and T-2 toxin, and a hyperestrogenic factor, zearalenone, together with the fatty acid esters of trichothecolone, scirpenetriol, T-2 tetraol, and zearalenone, were isolated from the flask culture extractives of Fusarium moniliforme Sheldon (IMI 225232) as well as from

35. Culture of Five Commonly Used Acid-Producing Bacteria on Banana Pulp
A significant fraction of the bananas and plantains produced in the humid tropics are wasted due to rapid spoilage. The use of acid-producing, anaerobic fermentation may be a safe and economical way to preserve the fruit in both large- and small-scale applications. The abilities of five commonly used, acid-producing bacteria to ferment media containing ripe

36. The Genetic Structure of Natural Populations of DROSOPHILA MELANOGASTER. Xix. Genotype-Environment Interaction in Viability
To investigate whether or not an excess of additive genetic variance for viability detected in southern natural populations of Drosophila melanogaster was created by diversifying selection, genotype-environment interaction was tested as follows. (1) Two karyotype chromosomes were used: 61 second chromosomes with the standard karyotype and 63 second chromoso
