Alternative substrates for the production of tomato and eggplant seedlings
Santos, Ana Maria Maciel dos; Silva, Maria Amélia de Oliveira; Sá, Daniele Alves de; Neves, Luis Paulo Ferreira; Gouveia, Fernanda do NascimentoThe objective of the work was to identify different types and proportions of compounds in the formulation of substrates for obtaining tomato and eggplant seedlings. Two experiments were conducted in a completely randomized design, composed of seven treatments consisting of the substrates (Tropstrato®, Solo + cattle manure, Solo + goat manure, Solo + goat manure + beef manure, Solo + beef manure + sand, Soil + g...
Genetic parameters of tomato families F2:3 in resistance to Ralstonia pseudosol...
Costa, Kleyton Danilo da Silva; Oliveira, Tâmara Rebecca Albuquerque de; Santos, Ana Maria Maciel dos; Nascimento, Maxwel RodriguesThe tomato (Solanum lycopersicum) is an important crop in Brazil, however, it is susceptible to different types of bacteria races. The objective was to study the genetic parameters of 43 F2:3 families of tomato in resistance to R. pseudosolanacearum and R. solanacearum. The families were obtained from the cross between the cultivars Yoshimatsu (resistant) and IPA-7 (susceptible). Two experiments were carried ou...
Progeny coriander resistant root-knot nematode
Santos, Ana Maria Maciel dos; Costa, Kleyton Danilo da Silva; Oliveira, Tâmara Rebecca Albuquerque; Silva, José Wilson da; Souza, Ênio Gomes FlôrCoriander is a important vegetable crop in Brazil, being widely consumed as a condiment and cultivated mainly in North and Northeast brasilian regions. Diseases caused by Meloidogyne species are one main causers damages of crop. In the literature there is no reported about identification nematoid resistant coriander genotypes. In this study was carried the reaction evaluation of a heat-tolerant coriander popula...
Identification of families F2:3 of homozygous tomatoes resistant to Ralstonia p...
Costa, Kleyton Danilo da Silva; Santos, Ana Maria Maciel dos; Santos, Paulo Ricardo dos; Silva, Adriano Márcio Freire; Sousa Neto, Eduardo Pereira deThe objective of this work was to identify homozygous F2:3 tomato families resistant to Ralstonia pseudosolanacearum and Ralstonia solanacearum. Two experiments were carried out under greenhouse conditions at the Federal Rural University of Pernambuco, one for each pathogen. We evaluated 45 treatments composed of Yoshimatsu (resistant) and IPA-7 (susceptible) and 43 families F2:3 obtained from generation F2. Ea...
