Resumo: The objective of this work was to quantify zingiberene contents in a segregating population (F2) of the second backcross generation to Lycopersicon esculentum after the initial cross with the wild species L. hirsutum var. hirsutum, and to analyse the relationship between zingiberene and both glandular trichome density on tomato leaves and levels of repellence to spider mites Tetranychus evansi. A spectrophotometric assay was used to quantify zingiberene in leaf disks. Trichome counting was made in paradermic preparations of leaf and mite repellence was accessed by a quick thumbtack assay. Indirect selection for high zingiberene contents increased both glandular trichome density and the level of mite repellence. Zingiberene in glandular trichomes therefore mediates mite repellence in the tomato population. Glandular trichome densities, especially that of type VI trichomes, were highly and positively correlated with zingiberene contents. High zingiberene levels and their relationship with both glandular trichome densities and resistance (repellence) to spider mites remained significant after two backcross generations, indicating an indirect selection for high zingiberene as an effective way of selecting mite resistant tomato genotypes.

Na quantificação do zingibereno, utilizou-se um método espectrofotométrico; os tricomas foram contados a partir de cortes paradérmicos e a resistência a ácaros foi avaliada por um bioteste de repelência. A seleção indireta quanto ao teor de zingibereno promoveu aumentos correlacionados no número de tricomas glandulares e na repelência ao ácaro, e o zingibereno nos tricomas glandulares participou efetivamente na resistência aos ácaros. A densidade de tricomas glandulares influencia de maneira determinante os teores de zingibereno, sendo que o tricoma tipo VI destacou-se por apresentar alta correlação com este aleloquímico. Os teores de zingibereno e a sua relação com tricomas glandulares e com a resistência a artrópodos-pragas se mantiveram ao longo dos retrocruzamentos, evidenciando a possibilidade de obtenção de plantas resistentes via seleção indireta para alto teor de zingibereno nos folíolos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonçalves, Luciano DonizeteMaluf, Wilson RobertoCardoso, Maria das GraçasResende, Juliano Tadeu Vilela deCastro, Evaristo Mauro deSantos, Nicolau MacedoNascimento, Ildon Rodrigues doFaria, Marcos Ventura2006-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7133Pesquisa Agropecuaria Brasileira; v.41, n.2, fev. 2006; 267-273Pesquisa Agropecuária Brasileira; v.41, n.2, fev. 2006; 267-2731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7133/4178info:eu-repo/semantics/openAccess2014-09-26T17:33:36Zoai:ojs.seer.sct.embrapa.br:article/7133Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T17:33:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
