Divergence genetic in Physalis species and interspecific hybrids based on morph...
Silva Junior, André Dutra; Zeist, André Ricardo; Leal, Murilo Henrique Souza; Oliveira, Joana Nascimento Merces de; Oliveira, Guilherme José AlmeidaPhysalis L. is one of the most important genera of the Solanaceae family, containing 120 species identified botanically. Physalis species have a great genetic, variety due to the high number of botanically identified species, which guarantees peculiar characteristics of economic interest. Despite the knowledge of these characteristics, little has been done for the genetic improvement of this small fruit. To sta...
Plastochron and yield of Physalis peruviana L. grown in different environments ...
Zeist, André Ricardo; Resende, Juliano Tadeu Vilela de; Zanin, Daniel Suek; Silva, Israel Felipe Lustosa da; Silva, Daniel Fernandes daThis study aimed to estimate plastochron, leaf area, and yield of Physalis peruviana seedlings grown in different environments and transplanted on different dates. The experiment was carried out in a completely randomized design, arranged in a 2 x 3 factorial scheme, namely: two cultivation environments (protected and field) and three transplanting dates (10/27/2013, 12/15/2013, and 02/11/2014). Four replicates...
Glandular trichomes that mediate resistance to green peach aphid in tomato geno...
da Silva, Alex Antonio; de Castro Carvalho, Regis; Carvalho Andrade, Marcela; Zeist, André Ricardo; Vilela Resende, Juliano Tadeu; Maluf, Wilson Roberto The aim of this study was to verify the resistance of tomato genotypes (crossed with Solanum galapagense) to the green peach aphid, Myzus persicae, and the association of this resistance with glandular trichomes. Leaf trichomes were quantified for seven F2 genotypes of the BPX-486 population derived from crossing S. lycopersicum ‘TOM-684’ and S. galapagense accession ‘LA-1401’, for the commercial controls...
Biomass association in specimens and interspecific hybrids of tomatoes
Zeist, André Ricardo; Faria, Marcos Ventura; Resende, Juliano Tadeu Vilela; Gabriel, André; Nonato, Julio José; Santos, Matheus Hermann dosThe objective of this study is to analyze the growth of wild species of tomato, of the cultivar Redenção and of the respective F1 hybrids of interspecific crossings. We evaluated six wild-type accessions (Solanum pimpinellifolium ‘AF 26970’, S. galapagense ‘LA-1401’, S. peruvianum ‘AF 19684’, S. habrochaites var. hirsutum ‘PI-127826’, S. habrochaites var. glabratum ‘PI-134417’, and S. pennellii ‘LA-716’) and th...
Cutting of Physalis peruviana on different polystyrene traysand substrates
Zeist, André Ricardo; Silva, Israel Felipe Lustosa; Lima Filho, Renato Barros; Neumann, Édina Regina; Giacobbo, Clevison LuizPhysalis peruviana in Brazil has its agricultural production limited by the lack of technical information about cultivation. The aim of this work was to evaluate the rooting of P. peruviana using different polystyrene trays and substrates. To run the experiment, in a 3x4 factorial design (trays x substrates), polystyrene trays (BPE) (Styrofoam®) were tested, with number of cells: [1- BPE1 (72); 2- BPE2 (128); a...
Tomato seedlings production by cutting according to the substrate and indolbuti...
Zeist, André Ricardo; Neto, Gentil Felix da Silva; Giacobbo, Clevison Luiz; Alberto, Cleber Maus; Shimitdke, FernandoThe tomato seedlings obtained by vegetative propagation have the same genetic characteristics of the plant. Internal factors such as hormonal balance and genetic potential, in addition to external factors, influence on rooting. The aim of this study was to determine the best type of substrate and IBA concentration effect on rooting of tomato cultivar Santa Cruz Kada®. For the seedlings production IBA concentrat...
