This study evaluated the diversity of cultivable plant growth-promoting (PGP) bacteria associated with apple trees cultivated under different crop management systems and their antagonistic ability against Colletotrichum gloeosporioides. Samples of roots and rhizospheric soil from apple trees cultivated in organic and conventional orchards in southern Brazil were collected, together with soil samples from an area never used for agriculture (native field). Bacteria were identified at the genus level by PCR-RFLP and partial sequencing of the 16S rRNA, and were evaluated for some PGP abilities. The most abundant bacterial genera identified were Enterobacter (27.7%), Pseudomonas (18.7%), Burkholderia (13.7%), and Rahnella (12.3%). Sixty-nine isolates presented...

Soil composition and nutritional status of apple as affected by long-term application of gypsum
Provedor de dados: 90
Autores: Nava,Gilberto; Ernani,Paulo Roberto; Sá,Alessandra Aparecida de; Pereira,Adilson José.
Gypsum does not affect the soil negative charges and maintains sulfate in the soil solution, making it one of the cheapest products to increase Ca activity in soil solution, especially in the deeper soil layers. Higher Ca levels in the soil solution can increase the uptake of this nutrient by apple trees, reducing the risk of physiological disorders caused by Ca deficiency. This study assessed the effect of long-term gypsum application on some soil properties and on the chemical composition of leaves and fruits of an apple cultivar susceptible to fruit disorders associated with low Ca. The experiment was conducted in São Joaquim, in the South of Brazil, from 2001 to 2009. Gypsum rates of 0, 1.0, 2.0 and 3.0 t ha-1 were annually broadcast over the soil...

Adubação de crescimento de macieira Cv. Catarina sobre porta-enxerto marubakaido em São Joaquim-SC
Provedor de dados: 94
Autores: Nava,Gilberto; Nuernberg,Névio João; Pereira,Adilson José; Dechen,Antonio Roque.
O vigor vegetativo e a capacidade produtiva da macieira são dependentes da adubação de crescimento ou de formação, a qual se baseia no fornecimento de N. A macieira cultivar Catarina, selecionada como resistente à sarna, tem-se mostrado promissora para as regiões de maior altitude do Sul do Brasil, mas, por tratar-se de uma cultivar nova, ainda não existem recomendações de adubação para a formação inicial das plantas. Por essa razão, conduziu-se um experimento com o objetivo de estabelecer a dose de N capaz de equilibrar o vigor vegetativo com a capacidade produtiva da planta. O experimento foi instalado num pomar estabelecido de macieira cultivar Catarina, enxertada sobre o porta-enxerto Marubakaido, implantado em 1998, num solo raso originário de rochas...

Macieiras 'Fuji' crescidas sobre Cambissolo e Neossolo foram tratadas com doses de N e K2O (0; 50; 100 e 200 kg ha-1 de ambos) por nove anos. As alterações da maturação e qualidade das maçãs, na colheita e após a armazenagem, decorrentes das aplicações de N e K2O, não foram iguais para os dois solos. Altas doses de N aumentaram o teor de N e diminuíram a cor vermelha e o teor de amido nos frutos, independentemente do solo e da dose de K2O. A massa dos frutos aumentou, e a firmeza da polpa diminuiu em resposta às altas doses de N aplicadas no Neossolo, independentemente da dose de K2O, o que não ocorreu de forma consistente no Cambissolo. A acidez titulável (AT) reduziu por altas doses de N em ambos os solos, quando se aplicaram baixas doses de K2O. Os...
