The introduction of rhizobacteria to the soil can be done via treatment of propagating materials. The aim of this work was to evaluate in greenhouse the influence of immersion periods of micropropagated ‘Prata-Anã’ banana seedling roots in suspension of different rhizobacterial isolates on the growth of seedlings and control of Meloidogyne javanica. The experiment was set up in greenhouse in a randomized block design in a 10 x 2 factorial scheme (rhizobacteria isolates) x (immersion periods: 60 and 120 minutes) with 10 replicates. The additional treatment (control) was composed of seedlings without any treatment infected with M. javanica. Treated seedlings were planted in pots containing soil: previously autoclaved sand. After twenty-four hours, suspension containing 3,000 M. javanica eggs was added to the soil. At 60 days, number of galls, egg mass and eggs per root system, number of second-stage juveniles (J2) per 100 cm3 of soil were evaluated and the reproduction factor was calculated. Shoot dry matter mass was also evaluated. Of the four rhizobacteria that reduced the reproductive capacity of the nematode, three were more efficient when seedlings were treated for 120 minutes. The treatment period of banana seedlings did not affect the shoot dry matter yield and all rhizobacteria increased the dry matter weight of seedlings infected with Meloidogyne javanica. It could be concluded that rhizobacteria have different treatment time requirements for seedlings to control the nematode, but do not interfere with the development of seedlings. Resumo A introdução de rizobactérias ao solo pode ser feita via tratamento de materiais propagativos. O objetivo deste trabalho foi avaliar, em casa de vegetação, a influência de períodos de imersão de raízes de mudas de bananeira ‘Prata-Anã’ micropropagadas, em suspensão de diferentes isolados de rizobactérias no crescimento de mudas e no controle de Meloidogyne javanica. O experimento foi montado em casa de vegetação, em delineamento em blocos ao acaso, em esquema fatorial 10 (isolados de rizobactérias) x 2 (períodos de imersão: 60 e 120 minutos), com 10 repetições. O tratamento adicional (testemunha) foi composto por mudas sem nenhum tratamento, infectadas com M. javanica. As mudas tratadas foram plantadas em vasos contendo solo: areia previamente autoclavados. Após vinte e quatro horas, suspensão contendo 3.000 ovos de M. javanica foi adicionada ao solo. Aos 60 dias, avaliaram-se: número de galhas, de massas de ovos e de ovos por sistema radicular, número de juvenis de segundo estádio (J2) por 100 cm³ de solo e calculou-se o fator de reprodução. Avaliou-se também a massa de matéria seca da parte aérea. Das quatro rizobactérias que reduziram a capacidade reprodutiva do nematoide, três foram mais eficientes quando as mudas foram tratadas por 120 minutos. O período de tratamento das mudas de bananeira não afetou a produção de matéria seca da parte aérea e todas rizobactérias aumentaram o peso da matéria seca de mudas infectadas com Meloidogyne javanica. Conclui-se que as rizobactérias têm requerimentos diferentes de tempo de tratamento de mudas para controlarem o nematoide, mas não interferem no desenvolvimento das mudas.

A jabuticabeira (Plinia sp.) pertence à família Myrtaceae e é nativa do Centro/Sul/Sudeste do Brasil. O objetivo deste trabalho foi determinar o pegamento e o crescimento inicial de mudas das jabuticabeiras 'Sabará' e 'Açu' submetidas aos métodos de enxertia de garfagem no topo em fenda cheia e garfagem no topo à inglesa simples. Foram avaliados o pegamento inicial aos 50 dias após a enxertia, o pegamento final aos 262 dias após a enxertia, o diâmetro e o comprimento da haste e o número de folhas emitidas aos 78, 107 136, 167, 199, 228 e 262 dias após a enxertia. A cultivar 'Sabará' apresentou maior pegamento inicial quando submetida ao método inglesa simples. A jabuticabeira 'Açu' obteve maior pegamento final em relação à cultivar 'Sabará'. A cultivar 'Açu' apresentou maior diâmetro, maior comprimento da haste e maior número de folhas emitidas. The jabuticabeira (Plinia sp.) Belongs to the Myrtaceae family and is native to Central / South / Southeast Brazil. The aim of this study was to determining the establishment and growth of grafts of jaboticaba trees 'Sabará' (P. jaboticaba (Vell)) and 'Açu' (P.cauliflora ) submitted to the cleft grafting and whip grafting methods. Were evaluated the initial establishment to 50 days after grafting, the final one at 262 days after grafting, the diameter and lengt of the stem and leaf number appeared to 78, 107 136, 167, 199, 228 e 262 days after grafting. The variety 'Sabará' showed higher initial establishment when subjected to the whip grafting method. The jabuticaba 'Açu' was greater on the final establishment. Cultivar 'Açu' showed larger diameter, longer length of stem and more leaves.
