| Abstract: The objective of this work was to investigate the effect of liming and phosphorus fertilization on the growth, mineral composition of the leaves, fruit yield, and mycorrhizal colonization of young feijoa (Acca sellowiana) plants. Treatments consisted of four liming levels - 0, 25, 50, and 100% of the dose required to raise the soil pH to 6.5 - and of five levels of P - 0, 60, 120, 180, and 240 kg ha-1 P2O5 -, placed in a randomized complete block design, in a split-plot arrangement, with three replicates. The orchard was established in 2010 with the Helena cultivar. In 2012, 2013, and 2014, plant growth was evaluated by measuring trunk perimeter, plant height, and tree canopy width. Mineral composition of the leaves, regarding P, N, K, Ca, and Mg... |

| O objetivo deste trabalho foi avaliar os níveis de expressão de β-1,3-glucanases e quitinases nos porta-enxertos de videira SO4 e R110, respectivamente suscetível e resistente a Fusarium oxysporum f. sp. herbemontis, bem como avaliar o efeito do fungo micorrízico arbuscular Glomus intraradices no crescimento, na expressão dessas enzimas e na supressão do patógeno no porta-enxerto suscetível. Foram quantificadas as atividades enzimáticas de β-1,3-glucanases e quitinases nas raízes dos porta-enxertos. Mudas do porta-enxerto SO4 receberam inóculos de G. intraradices e F. oxysporum, e foram avaliadas quanto ao crescimento, atividade das duas enzimas e sintomas de doença. As atividades das enzimas nas raízes do porta-enxerto resistente aumentaram entre 0 e 5... |

| Abstract In order to analyze the pathogenicity and antagonism between grapevine rootstocks and soil microorganisms, plant growth-promoting bacteria with antibiotic effect were selected from the phytopathogen Ilyonectria liriodendri, 2T-VSC-101 isolated monosporic, in in vitro antibiosis tests. The bacterial access that produced the largest zone of inhibition was used in the seedling biotization of the grapevine rootstocks P1103, IBBT481 and VR039-16. From the interaction between isolates of plant growth-promoting bacteria and Ilyonectria liriodendri isolate resulted in three bacterial isolates with control of the mycelial growth of the phytopathogen, all of the Burkholderia gender.However, the highest control bacterium, Burkholderia catarinensis sp.nov.... |
