Banana (Musa spp.) is one of the most cultivated and consumed fruits in the tropics. The low productivity and low quality of the Brazilian bananas are largely due to disease problems, among which are nematodes. In Alagoas, there is a lack of information on the nematodes species affecting the banana crop. The objectives of this study were to update the information on the occurrence of plant-parasitic nematodes in some of the banana producing areas in Alagoas state, to provide quantitative information on the frequencies and population densities of these parasites, and to identify the nematode species associated with the banana crop. The study was carried out from April 2011 to January 2012. Fortytwo soil and roots samples were collected from banana orchards planted with cultivars Prata, Pacovan, and Terra in 13 municipalities of Alagoas state. Nematodes were extracted from roots and soil samples using the maceration-centrifugal flotation and the centrifugal-flotation methods, respectively. The frequencies of the nematodes species extracted from the roots and soil samples were as follows: Helicotylenchus spp., 95% and 98%; Meloidogyne spp., 79% and 81%; Pratylenchus spp., 36% and 26%; and Radopholus similis, 38% and 21%; respectively. On average, Helicotylenchus spp. was most abundant with 2,359/ 50 g root, followed by R. similis: 1,359, Meloidogyne spp.: 810, and Pratylenchus spp.: 682. These high population densities show the need for research aimed at the management of plant-parasitic nematodes of banana in Alagoas state.

RESUMO: O objetivo deste trabalho foi avaliar a miniestaquia como técnica de propagação vegetativa e o efeito da aplicação de diferentes doses de ácido indolbutírico (AIB) no enraizamento de miniestacas de Lecythis lanceolata. Os tratamentos constituíram-se em duas coletas de brotações, nas doses de 0, 2.000, 4.000 e 8.000 mg L-1 de AIB, (fatorial 2 x 4), com quatro repetições, em delineamento inteiramente casualizado. O minijardim seminal de Lecythis lanceolata apresenta potencial para fornecimento de miniestacas. Não houve influência da aplicação de auxina no enraizamento das miniestacas, sugerindo que a espécie apresenta baixa capacidade de emitir raízes. TITLE: Productivity of mini-stumps and rooting of mini-cuttings of sapucaia (Lecythis lanceolata) ABSTRACT: The objective of this work was to evaluate the minicutting as a vegetative propagation technique and the effect of the application of different doses of indolebutyric acid (AIB) on the rooting of minicuttings of Lecythis lanceolata. The treatments consisted of two collections of shoots, at doses of 0, 2,000, 4,000 and 8,000 mg L-1 of IBA, (factorial 2 x 4), with four replications, in a completely randomized design. The seminal mini garden of Lecythis lanceolata has the potential for the supply of minicuttings. However, adventitious rooting is low, regardless of the application of auxin. |
