| Recientemente, el grupo fitoplásmico 16SrII, Candidatus Phytoplasma aurantifolia fue asociado con la enfermedad similar al cogollo arrepollado, Bunchy Top disease (BTD) en el Este de Cuba. El ADN total de más de 200 muestras de plantas e insectos se muestreó durante el 2005, y las que resultaron infectadas por el fitoplasma BTD, fueron evaluadas mediante un ensayo de hibridación de ácidos nucleicos no radioactiva (nrNAH). Los productos de PCR correspondientes al ARN ribosomal 16S de muestras seleccionadas se purificaron, marcaron con fosfatasa alcalina y se utilizaron como sonda para la detección de este fitoplasma mediante el sistema de marcaje directo con fosfatasa alcalina y detección quimioluminiscente (AlkPhos, Amersham Life Science, UK). El ensayo... |

| Thermal units or degree day systems can both be used to quantify relationships between plants and air temperature. The Northern Fluminense region holds no tradition for irrigated papaya (Carica papaya L.) cropping and, because of the need for irrigation, it is important knowing its growth and development characteristics under these conditions. This study aimed to determine the relationship between growth rate of papaya plants and degree days, and its effect on crop productivity, under different irrigation levels. An experiment was set up with the cultivar "Improved Sunrise Soil 72/12", in a randomized blocks design, with seven irrigation water depths and three repetitions; crop growth and yield parameters were evaluated. There were significant correlations... |

| The study focuses on the papaya production, including its cultivation, marketing, and process in three provinces in Thailand, namely Mahasarakham, Kalasin, and Roi-et. A survey with questionnaires was used in data-gathering. Key informants are 250 farmers who have papaya farms. SPSS program was employed in data analysis.It is found that during June to December 2008, farmers in Roi-et and Mahasarakham grow papaya as a supplement occupation, mainly for household consumption. On the other hand, farmers in Kalasin grow papaya for extra income. The average yield of Roi et, Kalasin and Mahasarakham were 92, 116 and 85 kg/tree/year, respectively. The papaya farm area has low fertile land with coarse textured soils or Loamy Sand which has its pH of 4.9 or higher.... |

| Objetivou-se determinar a viabilidade econômica e o risco do cultivo do mamão na Região Norte do Espírito Santo e comparar os índices econômicos com dados experimentais de irrigação e doses de sulfato de amônio. O experimento foi conduzido na Fazenda Caliman Agrícola S.A., em Linhares, Estado do Espírito Santo. Foram avaliadas, separadamente, duas variedades de mamão, Golden e UENF Caliman 01, em cinco níveis de irrigação (50, 70, 90, 110 e 130% da evapotranspiração de referência), combinados com quatro doses de sulfato de amônio (90, 188, 288 e 377 kg ha-1 mês-1). Na determinação dos riscos e índices da cultura do mamão utilizou-se o cálculo do Valor Presente Líquido, a Taxa Interna de Retorno, a análise de sensibilidade e o método de Monte Carlo. Os... |

| Banana, papaya and pineapple are the most consumed tropical fruits in the world, being Brazil one of the main producers. Fungi Colletotrichum musae, Colletotrichum gloeosporioides and Fusarium subglutinans f.sp. ananas cause severe post harvest diseases and losses in fruits quality. The aim of this work was to evaluate the effectiveness of five monoterpenes to inhibit the mycelial growth and conidia germination of these three phytopathogens. The monoterpenes citral, citronellal, L-carvone, isopullegol and a-pinene were diluted in ethanol to final concentrations from 0.2 to 1%. All monoterpenes were found to inhibit the growth of the three studies fungi in a dose-dependent manner. Citral was the most effective of the oils tested and showed potent fungicidal... |
